QB78D .22 after being subjected to some elbow grease and home tune. 3/4 in. 5 shot groups at 25yd. and chronied at @670 with JSB 18.1's. Put an Umarex "Compensator" (Pyramyd Air) wrapped with some carbon sticker to cover the holes and all I get is a short little "poop"! Typical QB trigger,did some judicious polishing an adjustments and it performs wonderfully.What a Bargain!! Bring on the QB Chief. Mike.
Thank You,Sir! I have approx. 100.00 into it (Excluding the old Simmons Pro Air I had sitting around.) Mostly just my time,as I really enjoy tinkering. It looks (to me) just as nice as my much higher end outfits. Mike.
