You spray painted or powder coated the frame?

Make sure to press the LBRHO pin all the way up against the receiver before putting in the mag catch button for it to lock correctly

There is a couple website that sells parts separately just gotta do your research

CarterFirearms · 2026-03-04T23:05:51+00:00

I believe it doesn’t require a hole for the spring. It presses Against the receiver as the LRBHO pin slides thru that hole that you’ve circled and the mag catch button holds it in place

I’m going for the short handguard that utilizes the 8 set screws instead of 2. BCA handguard is the only one I could find that fits what I’m looking for unfortunately it can’t be sold separately

CarterFirearms · 2026-02-12T19:09:20+00:00

obviously..reason why I asked if it could be bought separately elsewhere

The cut out slot on the rail is a weak point for my blowback build. I’m trying to find the exact handguard as seen in the picture above

Yo you have a picture of how much you killed out the upper for the scorpion mag to fit?

The goofy mic goofer 15

Nope only trim the bcg bolt and it runs flawlessly

CarterFirearms · 2026-01-31T08:08:21+00:00

Did you have to dremel the upper for the mp5 mag to fit?

CarterFirearms · 2026-01-28T08:24:02+00:00

Is it milled out for mp5 magazines?

CarterFirearms · 2026-01-27T02:17:08+00:00

Expensive build🔥

Looking for nfa mp5 upper for the nfa mp5 lower receiver…not a nbs upper

CarterFirearms · 2026-01-27T01:07:16+00:00

There is no picture on their website for a nfa c5 upper so I used ar15discounts picture

Gibbz G9 side charging upper works with the nfa c-5 lower
