5 Installed dozens

As a Gunsmith I see all the problems, These SS's are top shelf. Once installed I never see them again I stopped installing "gun show specials" Etc. as they are riddled with problems. If my customer wants to provide his own SS he gets it from GMR.

I had some problems at the beginning with 2-5 rounds being fired then a light strike connected the seller and he responded same day and helped me figure out the problem was not the safety and it was prior user from buying a used pew .

5 No Mods Necessary

My build is an 11.5" BCM Carbine chambered in 5.56/.223 with a H2 buffer. I needed no modifications to the parts or my carbine. This GMR kit was easy to install and performed flawlessly at the range. I'll be looking to pick up a few more, thank you!

Have never had an issue with any of the 15 triggers I’ve bought. If anyone has issues, there are plenty of guides and how to make them work. Sometimes you need to remove a little metal bases on your rifle. I have them successfully running with an AR9, AR22, and a bunch of 5.56 and .300blk.
