A2 Stock for AR-10, DPMS LR-308 and Similar AR 308 Rifles

Selecting the proper buttstock parts for an AR-15 can be confusing in it’s own right to guys who like to work on their own rifles. Now go and add the AR-15’s add it’s big brother the non milspec  AR 308 such as the ARMALITE AR-10 or DPMS LR-308 and there’s confusion and disinformation at every turn. Frustrating to say the least.  Here at 762ar.com we will slowly plug away at all these little details. Todays subject is the FIXED A2 BUTTSTOCK (or STOCK) and how it applies to the AR 308.

Item 1

Milspec or Commercial does not apply to the full length BUFFER TUBE

Item 2

The Buffer Tube is also referred to as Lower Receiver Extension Tube, Stock Extension Tube, Buffer Tube an other names I have probably missed

Item 3

AR-15 and AR 308 Rifles use the same Buffer Tubes

Item 4

AR-15 and AR-308 Rifles DO NOT USE THE SAME BUFFERS AND BUFFER SPRINGS.

Item 5

308 AR Collapsible Buttstocks and Rifle (Full Length  Buttstocks) DO NOT USE THE SAME BUFFERS AND SPRINGS. Just like their AR-15 counterparts.

 

When selecting a full length fixed A2 stock for an AR-10, DPMS LR-308 or other AR 308 you must select the appropriate Buffer Tube, Buffer and Buffer Spring .

PWS AR-10 AR-15/M16 ENHANCED BUFFER TUBE

PWS AR-10 AR-15/M16 ENHANCED BUFFER TUBE

The PWS Enhanced Buffer Tube is the first major upgrade and improvement to the buffer tube in years!
This one piece billet buffer tube is CNC machined out of solid 7075 aluminum in order to gain lightweight strength and reliability.  This unit is specifically designed to work fit the HK416, but will also fit all mil-spec lower receivers.
The Enhanced Buffer Tube will resolve any carrier tilt symptoms exhibited by a short stroke piston AR and will reduce felt recoil.
The most notable features on this buffer tube include:
  1. One piece construction eliminating the castle nut and ensuring that when installed, the buffer tube cannot become loose.
  2. Attachment system automatically indexes the buffer tube perfectly straight.
  3. The bottom of the interior buffer tube extends a lip into the receiver, supporting the bottom rear of the bolt carrier, reducing the carrier tilt present in some piston systems.
  4. A dead blow buffer is securely installed in the rear of the buffer tube to reduce carrier speed by an average of 10%, and dramatically reduce felt recoil.
  5. Two QD sling swivel attachments are machined into the front of the buffer tube allowing ambidextrous connection of your QD slings.
  6. The buffer tube is fluted to allow debris to be pushed out of the way, and a drain hole has been placed in the bottom of the tube, allowing for draining of water when the rifle is parallel to the ground.
