All parts are standard quality and function as expected

Anderson Manufacturing Mil-Spec Buffer Kit


An excellent but reasonably priced 7075 buffer kit. IHMO, better than the buffer kits that I had previously sourced at higher price points from other manufacturers. Nice fit and finish. Assembles and functions as it should, no surprises.

AR Build


Basic and practical.

Great Price, great service


Bought this and as always, have never been disappointed by any purchases made from primary arms. I recommend PA to all my friends

Works great!


Bought this for my first AR-15 build. Fit and finish were excellent. Spring is tight and functions well. My rifle is semi-auto and it double taps very well! functions flawlessly! Great product! works well with the MFT Battlelink minimalist stock! I bought that as well. Fit was very tight with the stock mentioned above!

Quality stuff


Bought this for my first build and all the parts seem like they are of quality build. They operate well on my build. Not much more to say.

Good product


Bought this to complete my Anderson lower I bought a while back. Fits great. No problems installing it at all. The only thing I didn't like was that the end plate I received was different than the pictured one. The one pictured was a standard one. The one I received was a dual loop sling mount style.
