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.


Pros
improves all performance
is really inexpensive

Cons
hard to install
literally nothing else

"Outstanding little upgrade.

They I-key's triangular top profile corrects the typical left curve produced by deformed hop arms, while the prolonged contact surface allows you pistol to lift heavy bbs with incredible accuracy and range when coupled with an Autobot / Decepticon bucking.

"I did not get the pink I-Key pictured. I got a silver colored one with a ridge in the middle. It works great with my Maple Leaf Aotubot 50 bucking. I can easily overhop .30s. Range is getting to about 200 feet off my porch with the green aotubot, crazy jet inner barrel, and I Key. Would recommend, it’s just a little tricky to install correctly and takes a little trial and error to get perfect.

"A little tricky to install in my Tm mk23. You have to make sure it stays straight and does not lean to one side (i used a small screw driver to push it in place) It works amazingly in conjuction with a PDI 6.01 inner barrel and a nineball bucking. I am launching .32s across my yard like nothing. This product is basically a flat hop for pistols.

"I used the Maple leaf hop up arm and I key in my TM g17 and got fantastic results, I have a nine ball hop up and 6.03 pdi 115mm and noticed even tighter groupings after I installed the I key, I will test this with the TM hop up arm in the future and if i get problems I will be back to report!

"This I-key works great - kinda. As long as you can get it to fit under the hop up lever arm just right, with out favoring the left or right side more. I think its supposed to nestle under the lever arm, with the straight part fit between the gap of the lever arm. But my WE GP1799 (same as WE glock internally) lever arm gap is not wide enough to fit it. Needless to say, it's not obvious how to best fit it, and might need some fiddling / altering to get the right fit. or even super gluing. But, once you account for the lever arm pushing down more on the left side than the right, and get this fit in just right, with the contour of it matching the contour of the bucking, it will really help your accuracy! I used this with a Maple Leaf Decepticon.
Also, do be careful on those WE pistols not to snap that lever arm. It's fragile.

"Got this for my emg sai 2011 gbb pistol. Would not fit right with the we/aw style of hop up arms. 99% without heavy modifications you can only use this for tm style hop ups. Maybe kjws but I haven't tried that lol

"Doesn’t fit the TM hop up arm correctly. Way to sloppy. Moves around. Had to glue it to the arm. Get a maple leaf I-key instead.

"Do not purchase the i key does not fit TM stock hop up and will move around even when you apply hop. It will move left or right in the hop up arm causing your bbs to curve.
0/10 waste of money.
