J&G M4 M16 HI CAP MAG 300RD M4 AIRSOFT AEG MAGAZINE

Cycled several 1000 rounds now and no hitches, works with both my CM-16 raider-L and my SRL. Slight loss of paint to the top of the mag where it seats in the magwell however looking used isnt a bad thing. This thing takes a beating and carries on and that scores highly in my book.Only drawbacks are the "Hi-cap rattle" which is unavoidable for the price it's a bargain back up.

Seemed a decent build quality, full metal, good weight to it, unfortunately it wouldn't even seat in my G&G CM16 Raider, full refund was offered straight away, can't complain, although will be picking my mags up a shop so I can test them before buying.

Bought these by mistake but they come with a key which inserts into a small hole on the side of the Mag, as a secondary way to wind on the mag! Brilliant! Stops you getting blisters on your index finger. Will use with my support rifle.

Recently brought a g&g cm16 r8-L Had heard about issues where certain m4 mags dont fit the magwell tightly enough causing feed issues. These were recommended by a fellow airsofter. Fit perfectly with no feed issues, cracking product for the price

This hi cap is great I found this works better than one that came with I airsoft rifle.

I bought two these for our cm16 raiders. They are well built and fitted into the magwell nicely. We put about 3000 rounds through them and they worked flawlessly. Obviously still early days reliability wise but so far so good. Recommended.

This is a great mag a bit awkward with blackviper m4 I own but still works with it

been used with madbull bbs and it feeds fine.I have three of them and they each have had around 5500 bbs thru them with no prob
