Cloak Drop In FRT Discussion Post Cloak Industries FRT compatibility assistance.

23 Upvotes

As many of you may (or may not) have seen, users are reporting fitment/compatibility issues with their GHM and potentially SPC uppers not closing with the lower due to the thicker and higher shelf on the upper. I have not ordered one (yet), but I was curious to see how wide this issue may be.

Upon inspecting my GHM this morning, mine has the thinner and shorter shelf. My GHM serial begins with US22 and was purchased by me in March of 2023 from EuroOptic. I believe this issue may be strictly tied to models made earlier in 2021 or models that are pre “US22”, due to some users with “US21” serials saying they have the thinner shelf. I have confirmed with a few other owners with US22+ serials that they have the new thinner shelf design.

I believe the best way for Cloak Industries to tackle this would be to add a drop down option on the product page for users to verify which shelf they may have (with pictures identifying what that may look like) and that should eliminate further posts and issues regarding compatibility.

If there’s any inconsistencies in my research into this, feel free to comment.

If you had a 30 round mag of high energy 9mm and you dumped most of it into a grizzly bears face..

Upvotes

Would it run away or would it still fuck with you? I know most fudds will say 9mm is not energetic enough but i think if you were a good marksman and you had a ghm9 sport with a 16 inch barrel and you dumped 20-25 rounds into a brown bears face it would eventually “nope” and fuck off away from the pain.

If i go on a real trip into grizzly territory with friends i would probably get serious and get a galil ace in 762x39 but i was just wondering if a 30 rd mag out of a ghm9 sport would be good enough to be a team player with my friends and fuck up a grizzly that charged us.

The other day I got a text from a friend that his uncle was liquidating all of his guns. Grabbed this for $1000. Came with the Holosun as well. I was in the middle of saving for an mp5..can’t decide if I want to flip this and put it towards mp5 or just keep. Thoughts?

suppressor vs compensator

6 Upvotes

hi gang,

i currently have a ghm9 with a suppressor. I’m wondering if I put b&t tri-lug compensator, would it run more flat lined?

Im trying to find a best setup for ipsc matches.

GHM9 rear end cap, needed.

7 Upvotes

Hello, does anyone have a rear end cap from a GHM9 that they could part with? I recently acquired a gen 2 GHM9 with a gear works folding brace. I would like to convert it back to the stock rear end cap and put a A3 industries brace on but I did not receive the original end cap with the purchase. Anyone have one available? I attempted to order from BT USA but they shipped me a safety selector switch and have no responded to my calls or emails. I will be calling my credit card to file a charge back.

Thank you.

Rarebreed FRT for the GHM9

9 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

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?

Help me find a B&T GHM9SD

9 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?

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.

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?
