I'm planning to get a Pdi Hop Up Chamber and I was curious if all the Prometheus AEG 6.03 Tightbore Barrels were drop-ins. Do they require any modifications at all?

Also for anyone who does have a UTG Type 96 or similar model, what should be the desired length of the inner barrel?
--I hear too short does not use enough of the potential energy (lower fps), while too long actually has no use.

The only one that is not a drop in is the m14 length barrels (499mm). The m14 specific AEG barrels are cut differently.

A 509mm barrel is the closest you can get unless you can find a 495mm barrel. The 509 is too long and will need to have end cap removed in order to fit correctly. Replacing end cap with flash hider and adapter is ideal or you can cut the barrel down 10mm like I did. Ideal length is 499mm but again the m14 length barrels do not work without modding.

I'm assuming you cut down the crowned side of the barrel. How did you re-crown it? Any performance issues?

Just get a silencer adapter. I wouldn`t cut the barrel. Unless you can cut it perfectly with out leaving like burrs on it.

I can do that.

I'll keep that in mind once I buy my remaining upgrades for my type96.

Could you please explain the er-hop and r-hop that you offer?

I tried searching, but failed O_O I could have sworn I saw it somewhere, but I can't find it anymore.

It is a patch that covers the barrel window, that offers superior hop due to the fact that it stabilizes the round better, applying hop over a distance. The r-hop is shorter, while the er-hop requires cutting of the hop window. The ER-hop is better for heavy rounds, and just in general, while the r-hop is better for people running short on cash.

Last question. So do these patches still provide an easy to achieve straight shot or does the hop curve much faster?
