DPMS 308 A3 RECEIVER HEIGHT

As mentioned elsewhere the current  DPMS  LR-308 receiver picatinny rail height is not compatible with most aftermarket handguards. Most attempt tso replace the factory forearm will result in rail heights that are not on the same plane.

Fortunately there are some new product’s on the way to change this situation.

I have created a new page devoted to help you determine which reciever you have as well as keep you up to date with the current aftermarket options. That page is here.

JP LOW MASS BOLT CARRIER GROUP for 308 AR – JPBC-4BA

As mentioned in a a previous post Brownells has been lstening to what shooters want and they have been adding 308 AR parts almost if not weekly. The latest edition is the JP LOW MASS BOLT CARRIER GROUP JPBC-4BA for 308 AR

JP defies current heavy is better logic of both the AR-15 and AR-308 platforms with the Low Mass Bolt Carriers and in the case of the AR-15 Low Mass Buffer.

I have not seen any analytical data on what system is best in the 308 AR and therefor have no opinion other than JP RIFLES knows the 308 and they have been doing it longer than most. Their rifles constantly win competitions.

I plan on contacting JP for a better explanation.

 

JP LOW MASS BOLT CARRIER GROUP for 308 AR - JPBC-4BA

JP LOW MASS BOLT CARRIER GROUP for 308 AR - JPBC-4BA

Here’s what JP says about the LOW MASS system:

We have our own purpose designed operating systems. For the no-compromise competition rifle, the LMOS™ offers the most significant improvement in the felt impulse of the rifle as compared to any modification other than the addition of a compensator. The complete system consists of our low mass bolt carrier and lightweight buffer conversion kit. By reducing the reciprocating mass, the overall impulse as felt by the shooter is further reduced, and bolt velocity is increased without significantly affecting reliability. JP LMOS™ equipped rifles have virtually no reciprocating mass feel.

Reliability with these parts is excellent for competition use. We’ve been using this system for three years without a malfunction at a match. Most shooters that use and maintain this operating system feel that it is a great performance improvement. Some shooters have even reported fewer unexplained flyers in their groups with the JP LMOS™ system.

The JP Low Mass Carrier works out nicely in the new type of civilian machined receivers like ours and the DPMS High and Low Rider series that don’t have a forward assist. Although it doesn’t have the forward assist serrations, it functions in military type receivers. It just won’t allow the use of forward assist on the receiver. Dust cover functions normally.

You may be wondering why our stainless carriers appear black. This is due to a new state of the art surface finish for stainless called QPQ (Quench, Polish, Quench). This is a five-step process resulting in a rock hard surface with natural lubricity. Some want the bright polished look and that is available on the JPBC-3 Low Mass carrier, but not the JPBC-2 tactical carrier.

The JP LRP-07 has our large format AR-10 type Low Mass carrier. The JPBC-4 AR-10 low mass stainless bolt carrier is also finished in black QPQ hard coat for superior wear and natural lubricity. The JPBC-4 will also improve the sight recovery on the DPMS LR-308 or the Armalite AR10. However, it must be used with a DPMS LR-308 bolt assembly, firing pin, cam pin and firing pin retainer.

Do not attempt to use the JPBC-4 with the Armalite bolt assembly, firing pin or cam pin. Unlike the AR-15/M16 platform on which just about everything is cross compatible, each AR-10 type rifle such as the JP LRP-07, DPMS LR-308, Armalite AR-10, Knights SR-25 or Rock River AR-10 is inherently different with only limited cross compatibility of components. Always check compatibility anytime you order aftermarket accessories for AR-10 type rifles.

CHEAP 308 AMMUNITION – GETTING WHAT YOU PAY FOR

This is one of my pet peeves. Guys go out and spend a $1000-$3500 of their hard earned cash getting their 308 AR just the way they like it. Then proceed to buy the cheapest possible ammunition they can find. Then they are surprised when the rifle wont function correctly.

Below is a scenario that plays out constantly in my inbox and forum.


Guy heads out to the range and is surprised when his shiny new rifle fails to function properly. He then bring the rifle home fiddle to with it, maybe get some opinions from friends or the internet and heads back to the range for more of the same. Inevitably either on his own or from gathering opinions the need to try an alternate ammunition become apparent. once again off to the range for more of the same. Now the shooter is angry that he spent all this money on a rifle that wont run. In anger he will call the weapon manufacturer tech support hotline. In most cases tech support will steer him to try a different magazine and maybe even another brand of ammunition. Back to the range and maybe the new magazine helped a little, small encouraging signs but the gun is basically a single shot. Back home and the shooter is livid back on the phone with the manufacturer for an RMA number. Two months later the gun will return with a note stating the chamber  was polished. Our excited shooter heads back to the range and the rifle still doesn’t function properly.


First off DPMS has gone so far as publish a list of AMMUNITION NOT TO USE IN ANY DPMS RIFLE INCLUDING THE LR-308.

Here is that list

Ammunition Warning

After extensive testing, we have found that only ammunition manufactured to SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications is reliable in DPMS rifles. DPMS recommends the use of high quality, domestically produced ammunition for best results and highest accuracy. For plinking and practice, we recommend only domestic, commercially manufactured ammunition. Please note: the use of hand-loaded ammunition voids the factory warranty. The use of all ammunition listed below also voids the warranty.

We have incurred feeding problems with the following:

    • Israeli ammunition
    • Korean ammunition
    • Chilean ammunition
    • Portugese ammunition
    • PMP
    • South African produced surplus
    • Lacquer Coated Ammunition or Steel-cased, lacquer coated ammunition
    • Wolf
    • Norinco
    • Silver Bear
    • Any steel-cased (coated or non-coated) ammunition
  1. We have reviewed several reports, from several manufacturers’, regarding problems using this ammunition. The problem appears to be the bullet contour and the overall length of the cartridge, which is contacting the rifling before firing. This is creating a gas port pressure and chamber pressure higher than recommended, therefore causing feeding and extraction problems due to the increased bolt carrier velocity. In addition, there is accelerated fatigue on internal parts. There are also indications that brass may be out of spec, which could create an unsafe condition.

    We have used this ammunition in the past for testing purposes and found the brass is extremely soft and can “flow” into microscopic pores and grooves in the chamber creating “sticky” extraction. This has been reported in many types of rifles, but is more prevalent in semi-automatic weapons.

    The problem with this ammunition is that the lacquer coating on the case. As the barrel heats up, the lacquer turns to a soft, varnish substance and upon cool down, becomes very solid and difficult to remove. This effectively creates an undersized chamber and creates understandable problems.

Your rifle is an investment and it only makes sense to choose quality ammunition for a quality rifle!


My Opinion

First off should you really be surprised when an ammunition that costs 1/4 to 1/2 the price of domestic ammunition fails to function properly in a weapon? I think not. Secondly you can swap one inferior brand for another and expect the same result.

What’s the point of shooting this ammunition other than cost? It’s not accurate despite most internet reports to the contrary. It’s not consistent from one lot to the next. So even if you manage to get a good batch it’s no guarantee the next lot will be any good. The ammunition is dirty as hell and possibly corrosive unless you believe the print on the box. You cant stake your life on it in a SHTF situation.

 

I’m not saying you  need to run out and buy Federal Gold Medal Match but you need to use some common sense. For cheap 308 ammunition look to one of the generic domestics such as Federal American Eagle or Winchester USA. If that’s still to pricey the PRVI PARTIZAN brand offers excellent value and accuracy. Avoid anything that has an animal in it’s name.

I think DPMS sums it up in one sentence. Your rifle is an investment and it only makes sense to choose quality ammunition for a quality rifle!


Advice for a 308 AR that wont cycle properly

If your 308 AR is DPMS compatible the simplest way to verify your 308 AR functions properly is to buy a MAGPUL 308 PMAG and few boxes of premium ammunition. The PMAG eliminates the possibility of a magazine issue as they are nearly perfect and the premium ammunition will be clean burning and accurate which will help you get that new 308 AR broken in and functioning like a champ. If you have an Armalite omit the magazine as there are no alternatives.

Note: A new 308 AR needs a lot more lubrication then an AR-15. Put some Mobil 1 on the bolt carrier and bolt ot maybe even your favorite gun grease on the bolt lugs. The BCG should be almost dripping wet with oil for the first few hundred rounds.

SI DEFENSE DPMS LR-308 15.5 JP VTAC Build

This 308 AR rifle build is an intermediate stage of another project. The plan is to use a matching SI Defense Generation II Upper and Lower Receiver, but at this time the lower is not in my possession. So for curiosity sake I took the SI Defense Upper and installed it on my DPMS LR-308 Lower from my DPMS LR-308 Precision Rifle Project on this site.

The upper consists of the following hardware:

  • SI DEFENSE GENERATION II STRIPPED UPPER RECEIVER

Eliminating Receiver Play in Your 308 AR – Accu-Wedge

So you gut your shiny brand new DPMS LR-308 home from the gun shop. You love everything about it except one thing. The upper and lower receiver have slop just like all of your AR-15’s.  So you think to yourself “on my AR-15’s I usually by those fancy adjustable pins or I cheap out and get an Accu-Wedge” but this is a BIG AR in .308 this must require something much more sophisticated or something bigger. Well guess what? The Accu-Wedge works in the DPMS LR-308. In fact the factory suggests it and sells it as. Fulton Armory also sells a device called the Accu-Wedge on their 308 Titan pages. See a pattern here?

Note:If you decide to install an Accu-Wedge in your 308 AR you might have to trim it a little to fit.

AR 308 AR-10 Triggers

.308 AR AR-10 TRIGGERS:


AR TRIGGERS .308 AR-10 DPMS

For the most part standard AR-15 triggers will work in the large frame .308 AR pattern rifles. There are however a few considerations to think about.

SAFETY: The first and foremost consideration is safety. While you may be inclined to go for the light pull weight your accustomed to in your bolt rifles that type of trigger is not advisable with these heavy recoiling rifles. A pull that is to light can possibly cause the gun to fire in uncontrolled full auto which will be dangerous to you the shooter as well as those around you. Guns designed for full automatic fire have their fire control system timed to fire at a predetermined rate with the gun not firing until the bolt is locked in firing position. Uncontrolled automatic fire can result with the gun firing without the bolt locked in place essentially possibly causing the gun to blow up in the shooters hands. The most common recommendation I read is not to go lower than 4# and if possible use a two stage trigger.

TRIGGER FIT – INSTALLATION: As I mentioned in the first sentence most aftermarket AR15 triggers will work in the .308. There is one caveat though. Some triggers will require modification or interference with the bolt carrier will result. So with that in mind I suggest sticking with triggers that are designed for the .308AR and designated to do so from the trigger manufacturer. If you are unsure call the trigger manufacturer or seek the help of a qualified gunsmith.

Brownells has recently added a dedicated section of triggers specified to work in the 308AR Rifles and AR-10’s


Geissele Automatics, LLC .308 AR AR-10 Trigger

Geiselle triggers are the standard by which all other triggers are judged with regards to AR-15’s as well as the .308 AR’s and AR-10’s

Geissele Automatics, LLC .308Ar,AR-10 Trigger

Fully adjustable trigger gives a smooth, two-stage pull with a precise “icicle sharp” break and ultra-fast lock time to minimize accuracy loss caused by gun movement during trigger pull.

Brownells .308 TACTICAL FLASH SUPPRESSOR

Low-profile, screw-on flash suppressor meets the needs of the most demanding tactical and competition shooters. Developed by Brownells’ in-house engineering team with plenty of input from the many dedicated shooters on our staff to give you a powerful flash suppressor that also helps reduce muzzle rise. Disperses combustion gases through five longitudinal vents to reduce the blinding, football-sized fireball of an unsuppressed rifle to a low-intensity golf ball sized burst. Greatly lowers the chance of muzzle flash giving away the operator’s position day or night, and helps preserve night vision. Vent walls are cut at an angle for maximum surface area to help cool gas and redirect it to counteract muzzle rise for fast follow-up shots. Solid underside prevents dust signature that can obscure the shooter’s view of the target or give away his position when shooting prone. Separate models available for rifles chambered in .223/5.56mm, .308/7.62mm, and 9mm. Unique “posthole digger” muzzle has cuts that form four chisel-points to provide a backup pain compliance weapon for hand-to-hand combat without creating unusually sharp projections that snag on other objects or cause unintentional injury during routine weapon handling. Precision machined from solid 4140 carbon steel bar stock and hardened to Rc 38-42 to resist blast erosion. Long-wearing, matte black oxide finish matches many factory barrel finishes.

SPECS: 4140 steel, black oxide finish, matte black. .223 – 23⁄8″ (6cm) long, .859″ (2.2cm) O.D. 3.3 oz. (94g) weight. ½”-28 tpi RH thread.

PWS CQB COMP 30

The PWS CQB COMP has to be the most expensive MUZZLE BRAKE available in 5.56 or .308. This is popular with SBR’s

PWS CQB COMP 308 MUZZLE BRAKE

PWS CQB COMP 308 MUZZLE BRAKE

From the manufacturer:

The CQB Comp, originally designed as part of the MK107 Rifle, provides as much compensation as possible while suppressing flash and sending all the blast forward of the shooter and those next to the shooter.

The CQB Comp features a 2 part design with a removable end cap for ease of cleaning. The primary function is to send all the blast forward while suppressing as much flash as possible. This product in no way compensates the weapon to the level of the FSC556 or our other comps, but it does serve the needs of those that requested its development.

CQB comps ship with the PWS Shim set, therefore additional mounting devices such as peel washers or crush washers are not required.

Aggressive, scallop-type cuts deliver superior gas dispersion to help stabilize the muzzle during periods of sustained fire. Special internal blast chamber with side-facing ports helps reduce recoil with no adverse effect on gas system function. Also provides enough flash suppression to keep flash out of the shooter’s line of sight.
