"There isn't much to say about this inner barrel. It's a simple brass inner barrel.
I ordered a 509mm one and received a 509mm one. It has a nice surface finish on the inside and the outside, the hopup window is cleanly cutout and the muzzle end is nicely crowned.

I can't say much about the effect it had on the velocity of the G36C I installed it in as it also received the JG MG36 Reinforced Handguard kit ID: 48890 and comparing the velocity of a G36C to an MG36 isn't really fair.

I can say that it looks quite a bit nicer than the original JG inner barrel the G36C had, although I am unsure how old and how heavily used the original inner barrel is.

"Works well, saw fps increase, only downside is it has no packaging whatsoever when you buy in it store. It was relatively clean and very straight

"You can�t go wrong with this barrel. Amazing price, great quality and great performance. No issues what so ever. I run it with a maple leaf 70 degree, prowin hop up and mad bull nub.
