I've been thinking about getting a start on gathering parts for an AK 105 build, only thing is that I will have to buy the parts, piece by piece (due to current money and time situations, no problems if it cost a little extra, nice things cost money), what are my options? I know if I buy the Bulgarian 12.5" barrel and trunnion block, I will need a compensator that will make the overall length 16 inches when permently mounted, will the compensator AK-USA sells in the picture below, make this a legal 16 inch barrel when permently mounted to BATF specs? Note in the item description below, the parts length is 4-3/4" so the overall barrel length should be 16 inchs if the ATF still approves of permently mounted compensators and flash suppressors making barrel lengths a legal 16 inches, as they do on AR's? I'm basically going after that AK 105 look, more then anthing else, I don't mind the extra length on the permently attached muzzle device. Of course, for the rest of the parts, I can get those from an Bulgarian AK74 parts kit.
