I'll bite.
I have done the trigger springs with a mcarbo spring kit, !cons the kits expensive I included a new detent and spring as well, while it lightens the trigger pull! it leaves slack in the take up, to get round that MCARBO sell a trigger with a adjustment screw added to it. I got around this by having the trigger drilled and a adjustment screw added! this takes up the slack, great improvement. I would like an after market trigger kit which is all alloy and gets rid of the weak plastic setup.
My barrel is cut to 12'' and still shoots and subs are all I shoot and they work at 100+, but prefer 50-60yards not as steady as I once was. This one shoots better than the Brno auto I had.
They can be temperamental at times!! but have only experienced a few jam ups in the last 1500 rounds and that could have been ammo and on another occasion just ready for a clean.
Here it is! rigged for night shift.
