Well Hello Ya'll.. I'm new to the site and just wanted to share my experience with the SG Bullpup conversion for my Yugo SKS..TOTAL NIGHTMARE.. Maybe if I had a "newer" type SKS, it would have been better but this whole conversion deal was a chore..And now after all is done, my 20rd mags wont load.. I can only shoot FMJ.. and they jam every other round.. I'm using ProMags..pretty reliable mags.. not sure why 1 out of the 4 I bought actually feed into the breech..Any way.. If I had to do it over again I wouldn't go through the hassle..
