AIM / Guarder Reinforced Steel Airsoft M4 / M16 Series Magazine Catch

"Great buy. I had to sand down a small part for fit, but took like 5 mins and it functions perfectly.

"I have a VFC M27 and as VFC owners know the M27 and 416 are picky with mags. I had a set of battleaxe mags that fit, but needed to be pushed in like 0.1mm to feed reliably. When I would let go of the mag I could hear the BB stopper on the mag close back up. I tried velcro but it didnt help. I took a gample and tried this mag catch, since its Guarder brand you can expect it to be near perfect dimensions. Now the mags fit with _0.1mm of vertical travel and the M27 feeds beautifully. Also it has a phillips head which is nice versus the annoying oem catch that needs to pushed in then rotated out AFTER you remove the bolt catch. This problem solver item gets 100/10 for me

"Did not fit my Matrix “Calico Jack” M4. The release button could be pressed into and get caught on the receiver. The long part of the release that holds the mag did not sit flush on the receiver so it did not hold my mags.

Going to try to make it fit because overall it’s a good part just be ready in case it doesn’t fit perfect.

"Worked Great in my Lancer Tactical LT19T! Thanks a lot, I was struggling with the default mag catch for the longest time and stripped the screw head and this saved me from going through a lot of pain!

Pros:
-Fixed the issue of a stripped screw and the mag catch always falling out.
-Not too expensive.

Cons:
-I am using with the Command Arms 140 round Mid Cap mags by King Arms and every time I reload, I need to give the mag an extra bump, to make sure its seated right, kinda like in video games and movies. Honestly not a huge deal breaker for me.

Overall, if you need another mag catch just to get the job done, I recommend this as a relatively affordable option! :D
