I've had the Flash in .22 on loan for a couple of weeks now. IMO its an ok gun. I shot it first out 30 yards when I got the gun and it shot great. The trigger was not good but not bad either. I shot the gun over the chronograph and got some great numbers for the first mag but with gun shooting too fast, the velocity fell quick. The gun would start at a plateau for the first 12 shots but then would drop off quick. The gun didn't have the traditional bell curve and if you could slow it down, the Flash should shoot great with more shoots. I never tried to slow the gun's velocity down because I thought the wear on what keeps the bolt close was not worth going through the trouble of tuning the gun. Years ago, I had a disco that use to bounce the bolt handle up and down after every shoot and I used a hair tie to keep the bolt handle down. You could do the same thing with this if you want but the gun would look getto. For this reason of the bolt jumping out of the barrel and effecting accuracy, I wouldn't recommend this gun. If the gun costed 100.00, I would tune the gun down, tie the bolt handle down with a hair tie, and put up with the getto look because the gun shot pretty good.
