RA-Tech CNC Aluminum I-Key for TM / WE Airsoft GBB Pistols

"Fit my KJW G26 hop-arm without issue, just what it needed.

"One of the best upgrades for the Hi-capa!

I use a Maple Leaf 50 degree bucking and in combination with the I- key and it provides a lot back spin on the bb. I bought this in order to use heavier bbs and I was able to over hop 0.45g bbs!

Assembly can be a bit tricky but you can find some videos online to help you. Fits right under the hop up arm.

"Put this in my SSP1 with a ML Decepticon 50 and it shoots way farther and is way more accurate.
