5 This thing is awesome.
Posted by Jayson DeNoble on Mar 23rd 2026
First off, I can’t believe how fast it arrived. Ordered on a Friday morning and arrived Tuesday afternoon. For context everything I’ve ordered from everywhere else, even local, has taken at minimum seven days to arrive. For those of you having fitment issues, the customer service at gmr is top notch. Got it installed and function checked on bench. Ready to try it at my range. Thanks again and look forward to ordering the next one for another build soon.

5 Kit R
Posted by Matt on Mar 13th 2026
The product is great, especially for the price. I own an original drop in FRT from another brand and this works just as good at less than 1/3 of the price. Installation is easy with simple tools that any AR owner SHOULD already have. I'm very happy with my purchase. ** Side note: the stickers that I received with my kit are A+ 100!!!

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.

5 Good communication

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.
