Re: Best piston driven AR
The BEST piston driven AR on the market? Man, that is purely subjective because everyone is going to have their favorite based on X, Y, or Z.
I really enjoy my POF and would love to have a POF P415 but as with anything, you will find both good and bad reviews where one guy claims it's the best rifle in the world and others won't piss on the factory if it's on fire.
The "best" thing you can do, if you can find the time and opportunity, is try to get behind a few and see for yourself. If you don't have that option, do lots of research and base your decision off of that. Take a look at not only Barrett but also POF, LWRC, LMT, PWS, and HK.
Best of luck in your research and decision!
