This website was born in 2006 as an attempt to bring some clarity to the confusion that surrounded the Armalite AR-10, DPMS LR-308 and Rock River Arms LAR-308 rifle platforms. These three brands were not the only 308 AR/AR-10’s at the time but they did dominate the market and the majority of the questions here and on the forum.
Today the AR-10, 308 AR landscape has changed tremendously. Armalite now offers the AR-10 in it’s preban configuration compatible with DPMS LR pattern magazines or more importantly Magpul LR magazines aka “308 PMAGS”. DPMS has modified the LR-308 several times. DPMS recently released the innovative DPMS GII which downsizes the LR-308 and brings it closer to the AR-15 in size and compatibility. Not to be outdone Mega Arms also has their own version of the G2.
The big change though as we predicted in 2006 shooters would seek out a rifle more powerful than the .223/5.56 AR-15 and what better choice than the father of the AR-15, the AR-10 (308 AR, AR308). Today nearly every AR-15 manufacturers now offers a .308 Winchester offering with many also including other short action calibers such as the 6.5 Creedmoor in their product mix. We had hoped that by now 308 AR/AR 308 designs would have standardized. That is simply not the case. Unfortunately the opposite is true. The AR-10/.308 AR market is now saturated with hardware. In an effort to differentiate themselves rifle manufacturers are taking substantial creative and artistic liberties in their designs.
