"I installed the 455mm length Crazy Jet inner barrel Maple Leaf 70 hop into my Well G74B CO2 GBBR.. fits ok. Didn't need to modify anything.

Pro-Tip: I had to slide the CJIB in hop-side first from the muzzle, cuz the threaded portion of the outer barrel has a smaller inner diameter and the outer stainless steel portion of CJIB has an ever-so-slightly larger dia. than remainder of brass barrel. It was definitely a handful to put the hop chamber back together.

Can't wait to test it out!


BTW: This inner barrel is approx. 2mm shorter than stock/oem Well inner barrel.
