Precision it says it in the name! Review by Devrin
Wanted to go with AP nitrate bcg for my M5E1 to match and I'm sure glad I did! The treatment was flawless and I love that fact that the firing pin retainer is the solid type not like standard cotter pins. Keep up the great products Aero Precision (Posted on 2/4/2018)
A no nonsense Nitride BCG; what more could you ask? Review by JARRAD
You pay the no nonsense price while at the same time still looking like a work of art. Bonus points for the stylized A normally I don't like Logos; but I like Aero Precision enough and their design is cool and simple enough for me to accept it and even like it. 10/10 purchase. (Posted on 4/1/2017)
