Ok basically I have a p90 and I'm not the original owner - the guy that first owned it did something with the piston or pistonhead and I'm having trouble finding out exactly what's going on. With the stock barrel the gun fires at a rather slow 280ish. I also have a lengthened madbull 6.03 TB that I use. With the tightbore the gun hits a steady 375-380. The TB is for an ak47 so it's significantly longer and basically I was wandering how the he'll the barrel makes almost 100fps difference.

Worth notin that the stock inner barrel also makes a hell of a noise compared to the TB but I'm assuming that's just the barrel not fitting as tightly round the BB and allowing noise and air to be expelled. Also sure he said something bout an unported cyllinder. I've never touched a V6 mechbox before and I'd rather not go digging to see what the he'll is going on LOL
