Great BCG October 17, 2018
Reviewer: M60hog from Idaho Falls, ID United States  
Ok, Just to start with I just got done testing this in two different AR type fire arms. The first was a BRN-16A1 "retro" AR15. Ten rounds, no misfeeds or any other type of malfunction. Absolutely flawless. I then removed it an placed it in a SIG M400 11 1/2in barreled "pistol". Same result. I have great confidence in this having tested it. Worth every penny an then some.

Nice BCG and even better customer service! March 23, 2018
Reviewer: Steve Johnson from Prestonsburg, KY United States  
Thanks for talking with me and doing up and above what most companies would do. I should've approached this differently but you guys have been great and please accept my apologies! This is the second on of these I've ordered. The first one has been great and I've put about 150 rounds through it without issue. Thanks Rob!

Cant go wrong March 22, 2018
Reviewer: POG from MI United States  
Installed on a 10.5in pistol build. Fit and finish were as expected with  MIL-SPEC. The carriers edges were perfectly smooth unlike the PSA one that came with my upper. Unlike the two BCM tried sending me the bolt didnt have any corners missing from the lugs. Case in point: $70-80 Toolcraft impresses me much more than the $170 BCM all day.

Replaced a PSA bcg since that one has over 1200 rounds on it and at this point I trust that if its going to break it will be after thousands more. So far I have put 100-150 rounds through the Toolcraft including two mag dumps. Conclusion...solid BCG that I will recommend to any friend or family. If you are more concerned with durability/reliability than shiny crap this is the one for you.

Semper Fidelis
