Hey obywon. you allready have a little bueaty of a gun with the 99, it would be well worth getting it tuned and barrel shortened/screw cut. My 99 barrel is 10.5 inches and still compact with a mod fitted. If you go for the shorten/screw cut route I'll send you an as new Edgar brothers moderator as fitted to an imp. Pm me your address if you want it and I'll get it posted off to you FOC.
