Aegis Custom FMG9 Conversion Kit for Elite Force GLOCK 17 Gas Blowback Airsoft Pistols (Color: White / Kit Only)

"Great gift from my brother. Works like a charm and gets lots of longing looks. Do make sure you match the mags to the model as the Glock licensed mags don't work with the KWA version. Make sure to store unfolded over long periods of time to avoid losing spring tension (learned that the hard way).

"solid kit, works great with the glock 18C from elite force as it's internals for a great SMG. To top things off with the build I used an AW custom drum magazine to have insane sustained fire capability with it on full auto. only issue is that the kit does NOT come with instructions for how to assemble

"I really like it was a little bit fiddly but I got it together. Put a vfc g18c in, no issues what's s ever.

"So small and compact and lightweight I love it, the stock is super sturdy zero wobble, and the polymer feels great almost as nice feeling as the poly used in eliteforce guns such as mp7 and mp5. I will note though as I do own a real glock 19 gen 5 and the real mags fit and with a tiny bit of modification, not that I will because it would be illiegal, but it could easily house a real glock.

"Overall, this is really neat kit and It's just as satisfying as you'd expect to flip this thing open! The build quality is better than expected: it's sturdy, feels solid, and doesn't rattle or wiggle at the hinges. It's pretty comfortable to hold even with large hands, and it's very lightweight.

This doesn't come with instructions, but if you can disassemble the pistol, you can 100% put this together.

Can confirm that you can put an Elite Force G18c gen 3 into this. HOWEVER, the rear sight will be a clearance issue. You will have to take the rear sight off, no big deal, but the metal piece provided to replace it is not flat enough to be flush with the slide (best I can explain is that the rear sight replacement bar needs to be flat instead of a "T" shape).
You can probably just remove some metal from this piece and be good to go, but I grabbed an Elite Force Glock repair kit since it comes with something that'll work and I don't want to be SOL if I ever decide to put a WE Glock into it.
Overall, it is a mild inconvenience when something is advertised on this site as compatible with your pistol, but then it is not that way right out of the box just because of one little part. Get your hands on a WE Tech Glock Gen 3 to make your life easier.

tl;dr: Great kit. Compatible with Elite Force G18c gen 3, but not without modification or getting your hands on the right part!

3/5 stars to Evike for the product description.
10/10 stars to Aegis for bringing such a solid kit back onto the market.
