PM-01 “Bolter” 9mm Luger Carbine
Disgned by Petr Malik
For Educational Purposes Only! I’m not responsible, in any shape or form, for the acts of others.
For those who do not know, the PM-01 (Petr Malik-gun #01) “Bolter” is the creation
of Petr Malik (a.k.a. Halik). The “Bolter” in PM-01 signifies the 35 plus screws used in its
design instead of permanent welds. It is chamber in 9mm Luger (9X19 for our European
friends) and utilizes modified Sten MKIII SMG bolt, magazine well and 32 round magazines.
1. Take the 1.5” Square Tube and cut it to 17.25 inches. Then marked off 8 inches from one
end of the tube, this is you action part of the upper receiver, the rest is the barrel
sleeve/shroud.
2. Ejection Port: Cut 1.25LX0.75W rectangular ejection port approx 7/8” behind the 8” mark
on the action part of the receiver. (See Pics)
3. Magazine Well Port: Get hold of Sten SMG template and cut out the magazine well cut-out.
Tape it on approx. ½” from the 8” mark on the action side and cut out.
4. Grind the semi-circular top of Sten magazine well down to flat so it can be fitted to the
upper receiver. Temporarily secure the mag well to the upper receiver with a silver solder.
5. FCG Port: Cut 2.5LX0.50-.75W rectangle FCG port approx. 3.5” from the 8” mark. Then
action part part of the Upper Receiver is now 90% finished. (See Pics)
6. Barrel Sleeve SlotsBarrel Sleeve SlotsBarrel Sleeve SlotsBarrel Sleeve Slots:::: The number of slots and their relative size is really up to you. Just
don’t forget that the trunion block is milled on the Mini UZI barrel 6” from the breech, so if
you have a gap 6” from the 8” mark on the barrel side of the receiver you will have to add a
spacer made from the ½ dia. black pipe. In my case, I went for 3 equally spaced, equally long
slots all the way around the tube, 5/8” in width. I also had to add ½” spacer between the
trunion and barrel block.(See Pics)
7. Bolt Handle Slot: You going to have to hold off on this one until you have the bolt fitted
inside the action to get the right distance from the top, but the slot should be 4LX0.25W and
5/8” from the 8” mark. (See Pics)
8. Rear Receiver Slant: Cut right triangles on left and right side of the receiver .75” vertical
and 1” horizontal. Cut it so that the horizontal cut is flat with the inner top side of the receiver;
DO NOT cut the top side of the receiver yet. Now make a relief cut on the inside of the top side
to make it bend easier. Heat it up with propane torch and bend to match the slant. Now cut the
top side 1-2mm after the bend. (See Pics)
9. Barrel Trunion Holes: Again, no rocket science here. There are two holes per side for 10-32
screws. Each is 3/8” from the edge. I played it safe and put 2 on each side but you could have
easily put one on each side or combination 1&2.
10. Rear Action Trunion Holes: Two holes on the bottom side 3/8” from the edge for 8-32
screws. One hole on each sides approx. 3/8” from the bottom
11. Rear Slant Cover: Cut 2”long flat piece from the remaining 1.5” square tube as described
in step #8. Make a relief cut and bent it to fit the slang as best as possible. Cut the excess. Drill
two for 6-32 screws to attach to the rear action trunion. (See Pics)
