Arcturus AR MOD1 Windowed EMM Variable Cap 30/130 Round Mid-Cap Magazine for M4 / M16 Series Airsoft AEG Rifles
(Color: Flat Dark Earth / Single Mag)

"These are great quality and for the quality you get, a very reasonable price.

Love the fact that you can change the capacity which makes it fun for challenging yourself or applying multiple mag changes in airsoft games.

The 135 rounds more or less is accurate, and sure more would be better but look at higher capacity magazines instead.

But if you want that variation in capacity and need quality magazines then just get these they are great!

"I bought three to go with my Arcturus Sword 13.5”.

They all work great, no feeding issues whatsoever, and they have a really nice follower.

10/10 Would recommend.

Only complaint is mag size, 130rd/30rd is cool and all but I’d like a 200+ rd midcap. Maybe in the future they’ll make more.

"Works well, can be a pain to load.
