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 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


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 .
