GL/SSC Block 2

I got the Colt 40mm marked receiver from ArmsUnlimited back when they were in stock for about 1400 and did a regular firearm transfer. I bought the 40mm barrel somewhere else and did a form 1 E-file. I haven’t seen any DD shells anywhere. I’ve only shot shotguns shells through it so far.

I see. If anyone knows a legal way to get WP rounds I need to know.

… for duck hunting

Is it possible to roll your own?

Not for duck hunting …

I missed this previously, somehow.

This. This build is the best I’ve ever seen. Came up while I was trying to research the 12.5” GL/SSC via Google. Beautiful.

My God!

I have always wanted a m203 on a rifle… but it has to come with a crate of HE 40mm

Looking sweet OP but do us a favor… post a video once you get that fun switch!

Update: LMT gen 1 FDE and enhanced carrier, tano G33, NAVSEA SU-231A, SSF trigger, VLTOR A5 H2 w/ green Sprinco, NT4QDSS, KAC 300m rear, Tango stubby.

I’ll try to get some vids soon. 203 is on my block 1 but it’s easy to switch it back and forth.

Block 1? You scored TWO unicorns? Jelly… trying to decide between looking for a “fake it” rail or just buying the Midwest ASDW upper for my “in-between” when I don’t need the compactness of a Mk 18 but want something handier than an M4.

Here’s the block 1, nothing super rare. I really like the 12.5 barrel length. I’d like to maybe put the Elcan back on the glssc one day and see how far I can push it on the long range.

That just a regular M4 RAS under there? I’m assuming the thing behind the FSB is a grenade sight of some kind… these little beasts are almost impossible to find tech data and part lists for.

Just a regular RAS. I’m gonna test how bad the POI shift/accuracy is on that non free float upper is compared to a free float 14.5 and see how the mounted accessories affect it.

I’m not a clone person. I started down that road and realized it seemed silly to me.

But dang, the uniqueness of the GL/SSC concept makes me want to do an “inspired by” copy.

I’m toying with a few ideas myself, all using pistol braces…
>5.56 “rumored variant” with 10.75" URX II and lo-pro block
>5.56 “inspired” FSP with Centurion C4 cutout rail
>5.56 “inspired” FSP with Midwest 20XG2 cutout rail
>.300BLK “Big Brother” version of any of the above
>.30-06 AR10-frame “BIGGER Brother” version of any of the above; unsure what rails would fit, but designed around the Garand’s AP Ball M2 round

How did I not see this thread yet? Incredible carbines there OP, you’ve amassed a nice and well thought out collection.

Thanks for the kind words! I’ll be posting more builds in this forum section. Here’s a better pic.

“Real” explosive, wp, etc, projectiles are vapor ware. Ive been looking for years and have never seen one for sale… which is stupid. Id be all over a 40mm if the ammo could be had.

Awesome build OP… one of the coolest guns out there… please post a video once the auto lower clears… Id love to see it in action.

HE is available but you have to have a legitimate need and duck hunting don’t fly. Testing body armor, well guess that’s legitimate.
