I was looking at buying a complete 9mm upper to go on a Glock lower SBR. I ran across some David Defense 7.5 inch keymod handguard, and a 4.2 inch ultra slim keymod handguard. This SBR will be primarily running suppressed with an Octane 45, but I want to have the availability to shoot unsupressed as well. Does anyone have any experience with David Defense? I don't know anything about them so wanted to hear some feedback about them before just jumping in. I like the 4.2 because of the shorter OAL but worry that the ultra slim handguard will be too small for the Octane to fit under. Thoughts?

Never heard of them.

Interested in replies.

Go look up Macon armory. Lots of 45 uppers and kits listed, but supposedly he has some 9mm rigs as well. Super super nice stuff, built like a tank

No one has had any experience with these uppers? I'm assuming that they are compatiable with a PSA Glock lower as well?

Maybe I'm dumb but I didn't see any uppers on there. Only a barrel, bolt, and a buffer.

Macon just does .45, right?

OP wanted 9mm.

I'm looking for a .45 myself, so good post.

I also like CMG, but I don't want to derail OPs thread.

I just checked and they do have 9mm stuff now.

I saw some parts, but I was looking to buy a complete upper and didn't see any on there...unless I'm blind.
