PPS 43 build advice

Posted by heat_it_and_beat_it@reddit | GunnitRust | View on Reddit | 22 comments

I picked up a PPS 43 parts kit recently. (From Centerfire Systems. Comes with 3 mags, mag pouch and a sling for $100.) I've ordered a receiver blank from Stenparts. I plan to buy the drop in semi auto trigger assembly. My only issue thus far is finding the barrel shroud section. (Anyone know where to find one?) I know a good gunsmith near me that should be able to convert the bolt to fire from the closed position. I also plan to convert it 9 mm and SBR it.

Anyone here built one? Any pitfalls I need to look out for?

You can make a die for the barrel shroud to press your own from some black pipe and angle iron. You'll need a press and welder anyways to form and build the flat.

I've come across mentions and pictures of the barrel shroud templates, but I haven't come across any for sale. I'd be willing to try that if I could find one.

I bent my own shroud for a centerfire kit so I can give you dimensions for the die. Keep in mind they're ROUGH and you'll likely have some heating and beating (username checks out) to get it looking proper. Going from a round to square profile while shrinking in diameter is super fun.

6 years late to the party, but would you be able to provide dimensions for the shroud die?

I'm in the process of building one. Its been slow going.

922r is a trick. Not sure how you plan to deal with it, but on an SBR, I wouldn't chance it personally.

Did your kit not include the barrel shroud? Most of them include the entire front end and are missing the rear portion of the receiver.

Its a very welding intensive project. Fitting the sight on, welding the receiver straight, welding a denial bar in place. I machined my own bolt and it was a bit of a PITA.

I ended up buying one of the IO pistols and plan to SBR that eventually. I'll hopefully get around to finishing my home build at some point.
