Angel Custom


The Angel Custom 9mm magazine adapter allows you to convert your standard M4 M16 Airsoft AEG from a 5.56x45 style magazine to a pistol caliber slim style magazine. The unique adapter does not require any tools and installation is as simple as inserting a mag into your gun. Once installed, the adapter uses its own paddle style magazine release to allow for ambidextrous magazine controls.

Compatible with all M4 AEG Receivers: By design, the Angel Custom pistol caliber conversion has an innovative nub where user can trim to fit tighter AR receivers like the KWA. For the most part, it will fit 99% of the M4 AEG receivers without modification.

*Disclaimer: (Will not fit Systema PTW, GBB, or other different platforms)


  • High quality 100 Nylon Fiber Polycarbonate construction

"Fit great in my G&G Femme Fatal m4, some slight modification needed tho in standard m4 mag-wells (slight sanding nothing extreme.)
Love the look, feel and functionality of the adapter, GET ONE TODAY!

"So I just got this. I use the cyma straight mp5 mags in it because it looks amazing and beautiful. I use a Lancer Tactical full metal M4 PDW, the adapter itself fit just perfect in the gun, tight enough that if you accidentally press the m4 mag release it won’t fall out. But the mag that I put in the mag well (the CYMA mp5 mags) would barely stick in and would fall out for sure in any game. So to solve this I got some duct tape and wrapped half the adapter in it. Then I put a piece of tape to cover the sticky part. This solved the whole problem. It stuck in there nice and tight. I run this with an extreme torque motor and a 11.1 lipo battery shooting around 22-23 ROF and it still feed flawlessly. The quality of this is very very very strong. It is plastic but I wouldn’t let that sway you from getting this.

"Looks fantastic in a stubby M4 (put mine in an A&K NS15 Charlie)
Gives it a unique PDW styling and just looks better on a compact gun than a normal M4 mag in my opinion.
Been using the CYMA 110rd midcaps and they've functioned flawlessly so far.
Highly recommend if you're tired of having a boring ol' M4 or want to roleplay a SMG user.
-Installation is as simple as popping it in the magwell
-Feeds without a hitch
-Looks slick on a PDW platform
-Fits VERY tight in some models (Particularly my buddy's Ares CCR, his might as well be glued in there)
-Reduced ammo capacity (but if thats a problem why are you switching?)
