"This is not gonna be a detailed review but I thought I could help people looking at this.

This is amazing however if you plan on getting it and you have a *AW CUSTOM HI CAPA* I'd suggest you also buy some upgraded return springs because the loading nozzle tends to stick in the bucking

"For the price, this is a good deal. As a drop in part, it's a good package - the tightbore is decent quality. Even though it is a 6.01, it's prety well burr free. It barely needed a cleaning on arrival, and the bucking (a 75 degree firefly soft) is actually one of my top choices, short of the pdi ones. Just throwing this in and tweaking it a bit consistently brought 80 foot shots from a stock hi-capa on a stock magazine. The flow valve is a bonus, too; the same effect can be had by turboing your own valves, but the drop-in replacement is a nice bonus. Essentially, the pack sells for a little under what you'd pay for a similar tightbore and a lesser bucking, with a flow valve on top as a bonus. It's no twist barrel with a w-hold bucking, but for the price it's totally worth it to drop into a stock hi-capa.
