Question: Will it work on a m4 airsoft mag
Document: My son bought 3 if these for Airsoft. He loves them because it makes them easy to get to from his vest during a match.
Get the real thing - same price or better than airsoft prices. I use them for both. Its a buy.
These work great with my HK mags. They fit snug and assist in mag changes which is what they are made for.
I have twenty 30 round aluminum Bravo Company Mags and these mag assist work great with them, it does not have to be a polymer mag to work.
Great mag assists from the pros at Magpul! They work great on my 20rd Ruger 7.62 mags; which I was unsure of when purchasing.
I am very please with my item. It fits great and looks cool. Thanks amazon for your help and thanks airsoft.
I hope you have a good grip. these aren't the easiest to install but the work great. i have reduced my reload times with these. it is much easier to yank a mag from a belt or vest. they also fit my metal mags as well.
The Magpul "mag pull" assists provide more gripping area (especially for USGI magazines) and a loop for easier retrieval from a vest pouch. They also shield your magazines from bottom impact. All in all, a good product.They may require some work to get on your magazines but are flexible enough for most. I have them on my PMAGs.
They are VERY difficult to put on and take off! I don't see the use for them - especially in Konnifornia where we have mag locks. You can't rest the rifle (I am using them on my AR-15 mags) on the mags any longer with these as they slide all over the rubber handle. The 3 I bought are tossed somewhere in the closet, never to be used again.You may have a different use for them as they didn't work for me...
Amazing allows you to operate your mags with ease. Works for both real guns an Airsoft . For Airsoft make sure you use midcaps no high caps evasive of the wheel
