Incorrect, the spacer is for the full size not the K.  I’m not sure why you are trying to tell me how to make something that I have had running for about 6 months now.

I probably wouldn’t use this thing in an expensive lower. I suspect the rotating cam will eventually wear out the selector hole anodizing.

Don’t the visits come much later by pulling customer records and shipping records? Curious why so many folks seem comfortable with that after the RBT experience yielded letters and visits… what am I missing?

Yeah, the ATF has taken a beating lately. I'd say until something is officially passed by Congress they'd be smart to not bring another case before a judge. They were told to return all RBTs that were confiscated (and ATF gave some BS about it being too hard). I think they'd be stupid to confiscate anything similar without a firm law to back the case.

I contacted GMR about this exact thing, inquiring about a replaceable bushing or insert.  He stated they have units with 16k+ rounds through them and no appreciable wear to the lower.  Not as big a deal in my $50 Anderson lowers, but a bigger deal in my $300 Lee's Sporting lower for the MP4.

I'd imagine that a range day should include a drop of SLIP2000 EWL on each side before firing.

Though, this IS something to consider for guys in the SBR NFA game. I wonder if a Teflon coating can be applied to a stripped lower after engraving to prevent wear in that area. Or if solid lubing would eliminate any appreciable wear.

I gave mine a really light oiling of Mobil 1 before assembly.
The edges of the groove don't appear to be sharp, and the imparted force is low.
Not worried about it on my SBR lower.
Biggest problems are cost of ammo and suppressor cool down time.
Now, I want an IAR that I can't afford to build or feed...

I'd add to that idea that even if Congress DID change the language of the definition of "machine gun" to include FRT style triggers, they would have to open up the MG registry for all units made prior to their reclassification. Ex Post Facto would absolutely apply here.

I could also see the expanded legal definition of machine gun as a possible way to strike down the NFA altogether.

The industry needs to pump out hundreds of millions of these things, drop in FRTs and Bump stocks to meet the classification of "common use" to have a chance I think.

The best thing Hoffman Tactical did with the SS was to release it to the masses.   I know of 3 outfits already that are selling metal SS's and at a price the typical recreational shooter can afford...well the safety anyway.  Not everyone wants to drop $350 on a patented RBT trigger pack just to dump a mag occasionally in a "full auto" type cyclic rate.  Then there are people just 3d printing em....  The genie is definitely out of the bottle on this one.

The SS spawned a 2-pack AP5 purchase and my first suppressor purchase.  I've ordered from 2 outfits that are making metal SS and now metal MP5 safety trips.  I don't like the push button aspect of the SS, but other than that...man...it appears to be a deal changer.

You also need a "safety trip" - you can 3d print one or GMR sells a metal one for $90. This resets the trigger in the AP5 since the bolt mechanism/geometry is different than the carrier in a regular AR-15.

Do you have the SS and a trimmed trigger or just the SS?

I would be curious to see how that works out if you dont mind sharing your results.  I think that interests me the most...a SS set up in a 308 with some Magpul D50s.   I started a thread in the AR Variants section to see if anyone had seen much success with the various 308 platforms but the thread didnt really go far.

The GMR site has some info on what specific measurements the lower and BCG need to be.  Hopefully the PSA rifle I have coming in meets the parameters needed.  I’ll post some updates here next week.

I need to try this with my 9mm upper


The 9mm BCG needs a lot of machining work.  Info also available at the GMR site.

The .22 kit sear trip bar will not work with the super safety.  You’ll need a dedicated sear trip bar (like the Bore Buddy version) to properly activate the cam lever.

The kits the GMR is selling work well with the SS's, well worth the money you'd hypothetically spend in Minecraft. I didn't see the original quote, so I can only assume someone was asking about the m16 trip bar or something and not the kit that GMR is selling?
Bore Buddy makes an SS specific trip, it's machined and a lot more money than the GMR version. And then you need the anti bounce weight also. It all adds up, but if you can get it run it's well worth it I'm sure.

ETA: If you watch GMR's youtube channel , they have a video on how their 22 kit installs on the CMMG bolt and a couple others dumping mags

The standard CMMG sear trip does not work. The SS will not reset the trigger.

However, it appears GMR has just released a “GMR sear trip” to work with the SS.  I believe this is a new addition to their website:

My CMMG dedicated 22 upper w/ CMMG auto sear trip kit (https://cmmg.com/auto-sear-trip-kit-22lr-ar-conversion ) does not work with my SS.  The printed .22 kit stuff from GMR works just fine though.  I'm used the printed bolt components, but using the metal lever from a "regular" SS kit.

You guys are wayy overthinking this. IF they have 16,000 rounds thru a test gun with no appreciable wear, you’re worrying about a few thousandths of an inch of wear on a “valuable” lower that you just burned $8,000 worth of 5.56 ammo thru….

If you’re going to lose sleep over it, send the selector and arm off for Nickle boron coating. That might even be a functional improvement.

There are three reasons to still buy the RBT….

1) the same manual of arms as with a standard AR15/M16
2) you’re a lefty and the semi position isn’t ideal for you



3) you want to reward reward Lawrence Delmonico for putting his freedom and fortune on the line so that you can play with forced reset triggers. As time goes on, we’ll see improved versions of these with match triggers and the like and there will be every reason in the world to buy those.

Correct.  You'll use the AR trigger parts in the Lee lower.  I bought 2 of them to go with my AP-5s, but I haven't installed them yet.  As soon as I finish my current motorcycle project I plan on having some "gun time".

Yes. If you plan to use a super safety in it, the mp5 style guns require a dedicated trip (slip trip?) that allows the carrier to activate the SS cam lever (as seen here): https://greymarketresearch.net/safety-products/hk-mp5-hk94-clones/

I believe the full size mp5 guns  might require a  buffer / spacer for the slip trip to work (as seen here):  https://skoprints.com/product/buffer-for-mp5/

It appears K models do not require this additional buffer / spacer…

I know this thread is about GMR and I've had great results with them over a couple of orders.

I've also had good results with Steven from https://skoprints.com   He has an active Telegram channel as well where he assists with questions, requests, installs, etc.  Just FYI.  I also like his little spacers things that serve to keep the trip lever centered in the AR style receiver.  I was concerned about that "wobble" when I played with a SS at first.

Just watched an acquaintance use the super safety in a suppressed AR pistol.

It worked really good (almost too good). He was burning through ammo at a furious rate.
