Brutuz62's Industry Brand QB78 Part I Nov 5, 2009

My new QB78 Deluxe, allready fitted a new breech seal and trigger spring.

Part II Nov 8, 2009

QB 78 Deluxe Take II, fitted a home made bipod rail, mounted an Airforce bipod, did some be-burring, polished the hammer spring unit, preloaded the hammerspring with washers, resealed the barrel and did some shooting afterwards. EDIT: REMOVED THE WASHERS. Inserted a piece of a Crosman hammerspring instead, work like a charm!!!

Part III Nov 10, 2009

QB78 Deluxe Take III. Replaced the hammerunit shims with a piece of Crosman hammer spring. Enlarged the probe porthole earlier but forgot to take a pic so that's in the vid as well. This one is about shooting indoor, 10 meter, 50 pellets and the results. Got about 47 good shots from two powerlets I kept in my pocket 15 minutes before starting this shoot. Check the other vids I made about this QB78 to see what else has been tweaked.Got a lot of usefull tips from Charlie da Tuna and the guys at the UK Chinese Airgun forum. Thanks !!
