My "Lil Dragon" gives me a case of perma-grin too >=)
Only had a few FTFs - bad ammo (primer showed strike mark)
And a bunch of FTE - usually magazine not seated properly or doing ALOT of rapid fire (~150rds in under 3 minutes). She gets hot and I think the spent round casings start to get a little stickie.
Other than that, I use a single point sling and it's dead-on at 50+ yards. Usually setup clay discs on the range burm.
hMy only complaint is a minor one... it rarily locks the bolt back and open after the last round. Makes you have to charge the weapon almost everytime.
