I used the generic filament picture.

A few descriptions, most started that materials will be acquired and manufacturing will occur after approval of form 1

You’ll need to specify the barrel length and overall length. Don’t end up shorter that what is on the form. There is some variation on the process between building a SBR from scratch and manufacturing a SBR from an already existing serialized firearm.

It’ll ask for photos.

Any existing SN should be clear, the eform will tell you what it needs to show.

That didn’t apply to me, so I used the same generic filament picture for cans on a few. Still waiting, but I was late to the party.

I tried this for a can, a SBR and a AOW. Now it’s hurry up and wait.

I agree, the metal feed lips work 👍

I believe the early versions of both the SD and SW frames had issues but the unseenkiller versions fixed that. I know his SWG frame works.

If you’re wanting an optic up front of the rear sight the ultimak will probably be your best bet. Any standard railed handguard will not hold zero. AKM pattern is the most common and a lot of the handguards out there will fit it. Anything Yugo, Serbian, krink, etc won’t fit.

Another red dot option is the Attero mount that replaces the rear sight leaf. I have five of these and all have held up for years.

Shit, sorry…I misread your post and thought you had it resolved and was just taking shit about Reddit.

A lot of folks were having issues and I know there was chatter last night… Thought it was all fixed

Stay away from reddit. Probably not what you want to hear but it’s a cesspool and you’ll always be walking on eggshells there

I’m assuming like the other poster your changing the receiver.

Look for the updated V4 with the additional material in front of the rejection port.

It will be some work to do it right but as long as your other hard parts are okay it’s doable.

Your other alternative is a metal receiver. Also doable, but more work for the rivets for an arguably better result.

Looks like a hammer follow device… Nothing to hold the trigger, no trip.

It’s been a available for 4 years and no one is talking about it, which says a lot.

Fusion has a free version.

I do it with STEP files in Fusion, I’m not familiar with other programs. What frame are you working with?

I like using a pocket for a m5 nut that’s under the trigger. The m5 is smaller than the factory grip screw but if you’re breaking m5 grip screws you’re doing something very wrong 😅

I really avoid using bolts in plastic threads if possible.

I’m using the Qidi software because there wasn’t an orca update for it yet. The Qidi is orca based, seems to be 99% the same

BLC has a couple betas using the Bersa barrels as well. I haven’t seen a complete build for one though.

How did you check/ set release timing?

I’m not sure about compatibility but overall there isn’t much out there for .45 magazines, I think partially due to lack of interest and platforms that need it.

Glad to hear you got it sorted. If be interested in checking out that mag when it’s released.

Yeah, I just grabbed my thinned mag and it definitely won’t fit in the Glock slide enough, by quite a bit. Factory Sten mags must be quite a bit thinner than the printed version

On hold. Printed trip bar version works but I had issues with the first metal bars, so that needs to be revisited. The metal is thinner than the plastic which affected release a bit.

It’s a fairly involved project and testing/development is slow going on my own, plus mag dump testing 308 gets expensive fast.
