EMG Troy Industries 250rd Mid-Cap Battlemag w/ T-Grip Magazine Assist for M4/M16 Series Airsoft AEG Rifles (Color: Black / Pack of 2)

"Great Mags, I own a Cybergun M4 and a Novritsch SSR4 and feed great.

feels heavy on hand great feelling on my opinion

"Very good mags....fit very snug with hardly any movement. Some rifs you might have to slightly enlarge the mag catch hole in the mag (raise the top of the cutout 1-2mm) for them to fully lock in.(I don't mind this cause I can get a very snug mag this way. )
They take the full 250rds and feed .25g bbs (indoor build) perfectly at 41rps & 330fps on my 18:1 DSG build.

"These magazines are solid. This fits perfectly in the following setups I own.: CYMA Platinum Umbrella Corp carbine (AEG-EMG-UC-CAR-D400-BK-GASP); Cybergun FN Herstal-Licensed SCAR-L by ARES (AEG-CG-200836-US); and the A&K M249 (AEG-AK-M249MK2MW). It fits very tight in the KWA T6 Ronin (AEG-KWA-104-01406) though, but no issues feeding. Just a very tight fit that I am not comfortable running in the long run personally. Not an issue, just a preference.

The mag holds all its BB's as advertised and I haven't had any issues with it feeding. The bottom "T" plug is removable as an option.

Overall, a great magazine that is a very high capacity for a "mid" cap mag. Look at the forums, talk to the community, to verify how this mag fits in your platform. Like I mentioned, it fits perfect in three out of the four platforms I have compatible with m4 mags. I highly recommend it.

As always, if unsure, buy only one magazine to confirm if you are comfortable with the fit, not only with this brand but with others if you are unsure if your setup is compatible.

"They don't fit in any of my 3 krytacs, but they are nice mags and feel great. Just can't test the feeding, do hold the 250 tho.
