I never understood why the A3 stocks are buffered but not the A2 version. I have a several MP5 hosts and prefer the fixed A2 stocks when shooting but didn't like spending the coin on the buffered version offered by one of the HK smiths out there.
Given I have several stocks to try my hand at modifying I set out to see what I could fab up on my own. I robbed a 1/2" thick buffer out of a Blackthorne folding stock and began. The Blackthorne is a US made version of the B&T sidefolder.
The toughest part is removing the back plate from the stock and then putting it back into the stock. These steps require spreading the "ears" of the stock. Welded a 4mm socket head machine screw onto the plate. Next I machined a plastic spacer to fill the recessed area of the plate so the buffer would sit on a level surface. Finished it in black Cerakote (thanks to my B.I.L.) to prevent rust.
Here are a few pic's!
Back plate with spacer, this is not the actual machine screw I used. You can see the 4 dings where the carrier has hit the plate. The spacer disc has not had the notches cut to clear the rails in this photo.
Buffer mocked up and bolted to the back plate, side view to show buffer thickness.
Complete and reassembled. The notch was poorly cut my me to clear the BHO on the .40/10mm guns.
Plan to test fire it later this week but the same buffer ran fine in the Blackthorne stock so I feel pretty confident that it will run in the 9mm gun. The real test will be the 10mm.
