"It's a great magazine, the shipping time was way too long. I ordered this product on August 6, 2021. It arrived on August 31, 2021. I almost thought it was lost in the mail. Aside from the long shipping time, this magazine is much lighter than the drum magazine, it makes a world of difference when your Thompson feels 5 lbs. lighter. Overall, a great purchase, would highly recommend for all AEG Thompson users to equip the stick magazine if you want your gun to be lighter.

"3-4 times the size of a normal pistol magazine but costs half the price. Works really nicely too.

"These are great! I upgraded both my M1A1 Thompsons and they shoot at 25 rps and 35 rps and the mags still feed well. Same goes for the midcaps.
