We have been reading about the COLT SP901 MODULAR 308 AR for some time with its unique MODULAR LOWER RECEIVER and it’s ability  to use MIl Spec 5.56 NATO/.223 Remington uppers on a 308 AR sized platform (DPMS LR-308, ARMALITE AR-10).  Today I noticed the COLT SP901 has made it to the COLT MFG website.




Here is what COLT has to say about the SP901.

Be it prairie dog hunting in Texas, whitetail hunting in Maine or elk hunting in Colorado, the Colt SP901™ is the rifle for the hunt. Chambered in the classic .308 Winchester (7.62×51 NATO) cartridge, the SP901 is the perfect choice for medium to large sized game animals. Exceptional accuracy is assured by its full floated, 16″ chrome lined barrel and one-piece monolithic upper receiver, suitable for mounting your optic of choice. Keeping the varmint hunter in mind, the .308 Winchester upper receiver group can be easily swapped out for any Mil-Spec Colt upper receiver chambered in .223 Rem (5.56×45 NATO). The fact that all operating controls are ambidextrous, including the magazine release, bolt catch and safety, makes for versatility and ease of use. You can depend on the new Colt SP901 to take the shot of your lifetime!

After only a few short weeks my of waiting the MEGA ARMS MA-TEN 308 AR RECEIVER SET arrived exactly as scheduled. My first impressions out of the box is very good. The units have been manufactured and finished flawlessly.  The MEGA ARMS MA-TEN 308 AR RECEIVER SET will be used in the #3 308 AR build project at 308AR.com.






Sun Devil Mfg Entering 308 AR Market

Sun Devil MFG has begun production of DPMS pattern 308 AR  receivers.

Here is a quote directly from Sun Devil MFG

We are machining the .308 lowers now.  We should have the uppers ready to machine in 60 to 90 days.  The MSRP is $249.95 for the lower.  They look very similar to our AR15 receivers. They are DPMS compatible and they also have the tension screw.



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.

.308 DPMS SASS Barrel – Muzzle Threads Removed and Barrel Crowned

I recently came upon a good deal on a DPMS 7.62 SASS Teflon Coated, Fluted Barrel. The problem is I cant have a threaded muzzle in my home state so the threads needed to go.

Rather than send the barrel out to a gunsmith I decided to machine it myself in the lathe at my day job. It was pretty easy and I think it turned out well.

Here’s what I did.

  1. I wrapped the barrel with a precision shim stock perfectly for nearly 360 degrees. This was done to protect the teflon finish from the lathe jaws.
  2. Then I placed the barrel in a 4 jaw chuck. I used the 4 jaw because its the easiest way to get the bore centered.
  3. I indicated the bore and adjusted the chuck until the bore was rotating perfectly centered.
  4. Next step was to remove the threads from the muzzle
  5. After removing the threads I adjusted the tool holder to give me the 11 degree crown.
  6. Cut the crown to a mirror finish

I have read that a brass ball with lapping compound  is typically used to fine hone where the crown meets the bore. I decided to skip this step for now just to see if it matters.

AR 308 AR-10 Triggers



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

Yankee Hill Machine .308 Phantom 5C2 Comp/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.

Thread protector


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



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.
