Thermold Master Mold AR15 Magazine, 5.56 (223), 20 Rd

I bought a case of these mags a few years ago. Used 25 mags at a training course where I shot over 500 rounds using a S&W MP AR15. Used Wolf ammo. Never had a jam or misfire. Other people made fun of me because I wasn't using my 30 round pmags. When doing drills on the ground and laying behind barrels you don't have to worry about turning the AR sideways to deal with the long magazine. I pulled 5 mags out of my safe that have been loaded 18 rounds each for 2 years. No issues shooting on same platform. When I bought these they advertised that the Canadian military used the same mags. I gave several out as gifts and haven't had any negative feedback. Still own several magpul pmags but prefer the 20 rounders. Would recommend.

I have four of these and only two of them work most of the time. Same results in three different rifles. The two that don't work cause failures to feed and double-feeds. You can also forget about keeping them loaded, as over time the cartridges will eject themselves. These are low-quality mags for range-use only. I only recommend these to those who wish to practice clearing jams.

This mag works great and is the perfect size for shooting with my bipod and windham AR15. I have 4 and never a problem. Easy maintenance.
