WOW. I received the new TECHT L7 bolt kit as a trade for the original ( free of charge, just send it in) and what a difference. I set my bolt up with BOTH firing can sleeves to boost pressure to about 190-200 PSI. It was only about 1/3 of a turn UP on my reg to re-adjust pressure and WOW what a big difference. I went from a hopper and 5 pods to a hopper and 6.5 ish ( still had air left) in a 71/4500 dye tank.
the kick was AMAZING low and super fast. HAD ONLY 1 breach break all day and we were playing in a MONSOON here in vancouver ( bout 55 degrees and POURING rain all day) on NXL ramping.
i only ask that they include a few CRITICAL ( ie inner top hat) o rings with the bolt) cause if they go, you are hooped til you can find some at a shop or elsewhere
This bolt is probobly the best $80 you can spend on a PMR. Not only does it add HUGE amounts of efficiency, but decresses kick and speeds the gun up a lil w a faster cycling rate.
Since you got all the kinks worked out how has the bolt worked? Is there much kick (compare it to stock please)? Have you even played a single (full) day with out having to jack with it? Would you still recommend it after all the problems you have had? If the stock bolt is 30+ bps capable, it really isn't necessary for speed... Kick, lower dwell (making it easier to cycle faster) and possibly accuracy(?) seem to be the main point for changing it right? Does it accomplish these things?
