Dynamic Precision Enhanced Hop-Up Chamber Set for TM Hi-Capa Airsoft GBB Pistols

"So I originally got this for my SSP1 and it fit well...but had one minor detail, the stubby part that goes in the recoil pin was way too long. But I removed it and I put it in and it fits great!! It doesn't move, budge, or come apart!! I really suggest this if you are going to get one for your SSP1!!

"This is a very nice hop-up seems to be durable I do like the fact that there is a grub screw on the Hop of wheel to really make sure that your hop isn't turning off when firing the only problem I had was when I removed my inner barrel from my outer barrel I bent the pin that the recoil rod sits on other than that perfectly fine very very universal will definitely fit in any kjw TM or we tech hi-capa or 1911's not a bad idea for an upgrade but would definitely keep in mind that the threads could possibly strip easily

"Terrible quality control. I ordered one, came defective. Replaced it. Exact same defect.
