"Works on the WE-Tech Bulldog / PX4

I bought the 97mm for the full-sized WE-Tech Bulldog / PX4, even though I can't put on a tracer with the included threads (it won't properly cycle otherwise due to it being longer than the stock inner barrel), it allows for the gun to beam with the proper hop-up setting. If anything if you happen to fancy that gun, buy this automatically, while its difficult to change out the inner and bucking, it's worth it once you get it in.

Now imagine that with the other gas consistency mods available for the gun...

"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.
