Semi Only Beretta 38A Concept Design (click here to download as a PDF file. then select save)

OK...After a lot of feedback from all of the great guys on Weaponeer.Net and also talking to several people who have been involved in this type of semi-auto design, here are is the latest version. 

NOTE: This design has not been reviewed by the BATF and is offered as a "Concept" on a way to approach a semi-auto build. Remember, any build must meet NFA/BATF guidelines.

You would also need to mill the feed lips on the bolt and drill a hole for pinning the firing pin.

Here's my logic as to why this would be a legal design... AND now the logic of many others!!!

1. Even though this is an original  ID receiver, the new ejector/ rail will prevent the installation of a F/A bolt.
2. The lower, with the modifications for the SKS trigger group, would not allow the original F/A fire control group to be installed.

**An AR trigger group could also be used, though you may have to adjust the bolt dimensions and you would still need to widen the lower or cut down (width) of the AR fcg. Also, the stub that this design is using to trip the SKS trip lever would have to remain unless you made a longer bolt slot and installed a fixed bolt handle that would move with the bolt. (the stub keeps the bolt from rotating within the receiver)

Why I think this would be a good working design...

1. No tricky slide hammers
2. No special small diameter springs to compress/ fail
3. Proven reliable SKS trigger group (could also be done with an AR fcg)
4. Solid Sten/AR spring
5. Bolt will be almost the same length as the original for good travel and function with the spring.
6. Modified Bolt will be the tried and true Beretta bolt on the business end.

Slot in bottom of bolt could be done with a dremel and abrasive cutting wheels.

Custom "Lowers" for this design will be available from us.
I recommend fitting your SKS trigger group to the lower Before cutting your bolt to verify your bolt requirements.

Below are some pictures of a Beretta semi-only build that were sent to us by a customer in the Midwest.

Let's see what we have towards complying with 922r.. (counting any of the modified parts as still being "Imported") 

(1) Frames, receivers, receiver castings, forgings or stampings (US MADE)
(2) Barrels (Imported)  ( 1 )
(3) Barrel extensions (US MADE)
(4) Mounting blocks (trunions) (N/A)
(5) Muzzle attachments (N/A)
(6) Bolts (Imported)  ( 2 )
(7) Bolt carriers (N/A)
(8) Operating rods (N/A)
(9) Gas pistons (N/A)
(10) Trigger housings (Imported)  ( 3 )
(11) Triggers (Imported)  ( 4 )
(12) Hammers (Imported)  ( 5 )
(13) Sears (N/A)
(14) Disconnectors (Imported)  ( 6 )
(15) Buttstocks (Imported)  ( 7 )
(16) Pistol grips (N/A)
(17) Forearms, handguards (N/A)
(18) Magazine bodies (Imported)  ( 8 )
(19) Followers (Imported)  ( 9 )
(20) Floorplates(Imported)  ( 10 ) 

a) No person shall assemble a semiautomatic rifle or any shotgun using more than 10 of the imported parts listed in paragraph (c) 

So, based on the above and "Not" counting the "Modified" bolt or SKS trigger assembly as "US" made, you would still be legal, as you are only at the "Max." of 10 imported parts.
