The rail was lose on mine as well,found out after shooting it for a few days.
Decided to do a sound comparison on the donny tanto ,with and without, stock 98.9 with tanto 87.1,this is with four holes drilled at the base of shrould and the magic eraser diffuser mod ,later today after mail arrives I'll install the Haji stripper and baffles and measure again, over 10 db is alot of sound change. But at 150 dollars it ain't cheap , the haji is 40 plus shipping so that might be the best bang (or lack of ) for the buck.
Is the avenger shroud support like the liberty? Does it have that solid plastic slug about 2 inches from the end of the barrel to keep shroud, barrel alignment?
Well, fedex screwed me over. After 4 days of the tracking report saying it would be in today and sitting home waiting since its a signature required item it did not show up. After getting no satisfaction with the customer service rep I spoke to the supervisor who did nothing for me either. Looks like my wife or I have to sit home all day again tomorrow waiting for fedex to do their job.
