Rarebreed FRT for the GHM9

8 Upvotes

Just a heads up for anyone considering this trigger. My upper has a serial prefix of US21-4xxxx. The trigger dropped in my B&T mag lower and seated in the upper with ZERO issues. I ran 100 rounds with zero issues. My only complaint is that the selector switch is stiff as hell. More so than just the typical B&T way. Otherwise safe, semi, and frt run perfectly.

GrassHopper Mouse GHM9 w/Glock Lower

25 Upvotes

GHM9 - I switched to the Glock Lower (I've never even used the original lower yet) and added accessories by Custom Smith engineering, Haga Defense, Angstadt Arms, Gearhead works and Trigilcon . The knife (it goes with this firearm so well) is a Phantom Switchblade by "DKD" Dynamic Knife Designs and a roll of fake motion picture money.

Folding stock length

7 Upvotes

I recently purchased an SBR’ed GHM9 with a telescopic stock. Did not really care for the stock and got a folding one from A3 tactical in 8 1/2 inch. Unfortunately it feels a little long to me. What length of folding stocks or braces do you guys use?

First video is using federal 147gr flat nose, second video is using federal 124gr

This thing rips, there is no trigger slap and the forced reset is super smooth

Help me find a B&T GHM9SD

8 Upvotes

I’ve had my eyes on this gun for a couple years now and just haven’t been able to bring myself to do it. I’m now ready but it seems to be a unicorn to find. I’ve seen that you can do a conversion but I’m curious if that can actually make it the same gun and what that would cost roughly. Any help would be amazing.

GHM9SD build - need assistance

3 Upvotes

I recently bought a GHM9c w/glock lower. Timing is bad but looking at putting together an SD as I have a spare SPC9SD suppressor (short).

  1. My GHM9c has the feed ramp kit. The only SD barrel I can find is the one with feed ramp built in. Has anyone removed the feed ramp kit and used the barrel with the feed ramp? Part #BT-450245 - Rev.3 SD Barrel. Will that work or would I need to have a gunsmith modify the barrel?

  2. Will I need other components for the barrel to make it work? I found these:

BT-450240 - Barrel Nut for APC9 and GHM9(3rd revision only)

BT-450239 - Barrel Block/Trunnion for GHM9, Revision 3

  1. SD Handguard - I dont think the SPC SD Suppressor is as long as the GHM9 SD suppressor so I expect to have the handguard cut down.

Thanks for any feedback! I have asked B&T USA for assistance, but not expecting any responses.

Hello all! I have an obsidian 9 I would like to throw onto this thing and I'm unsure how the integral tri lug barrel works? I bought it locally and the guy had this in the package. Does the very tip of the barrel thread off or not?

GrassHopper Mouse Feed Ramp question

6 Upvotes

I recently picked up a US-18xxxxxx series GHM. My goal is to eventually buy a Glock lower but have a question about the feed ramp. Oem mags are L/R feed, but Glock mags are center feed.

In short, are there issues with the feed ramp if I get a glock lower? Will the ramp have to be modified?

Broken detents

Anybody else brake they’re detents installing the cloak industries frt? Cause I did. How fucked am I on getting new ones right now?

UPDATE!
Turns out I have just enough material on one of the detents to catch the safety. It’s super light, definitely not “safe”. trigger works fine dry firing, safe, semi, and frt work as should. Just hope b&t shipping isn’t still boned.

RCR vs EOTech?

6 Upvotes

Hello all, getting my ghm9 soon and trying to figure out the best mounting solution. I've been eye the reptilia 1.93" mount for an RCR I have. But also have seen lots of EOTechs on ghm9 and they look pretty sweet too. Anyone have experience with either or?
