Linear moving angled wedge, turns out it’s similar to the savage a17, uses the same concept.

Have any animations of it in action?

No, but there is an animation of the savage a17 on YouTube, which has a very similar delaying system

I'll have to look it up when I get a chance, but how does it compare to lever delay like in a Famas?

The luger we have at home

I am a big fan of late 1800s to early 1900s firearms, wanted the trigger guard to reflect that somewhat lol.

Have you gotten this to the point of test firing yet? I'm very excited to see progress on the DIY delayed blowback front.

Still ironing out details, I will be doing test firing on private land after I move, so it’ll probably be a few more months. Working full time as well, so it’s been tough to dedicate time to this.

I hear that - I'm also in the midst of a move. Life gets busy. Nice work though!

Huge fan of the shape of it, any chance for an FRT/Binary for it? Love that it looks like a space pistol from an old twilight zone episode or sum

Thanks! I think since it has a 2 sear config, someone can def figure out a super safety for it.

Sweet, I can’t wait to see this thing progress I’m def gonna need one

How is this on muzzle climb compared to roller delay?
u/Admirable_Scholar_36 · 2025-06-30 21:27:37 UTC · score 3
I don’t believe a delaying mechanism really has much to do with muzzle climb, as it doesn’t change how gas is ejected/directed from the gun.
