The Product is mostly reliable, being able to interchange with the original clip. But sometimes the bullets stick in it. It was also a diifferent material than the original clip, or at least the one I got was different. But overall this is a good product, also giving you the advantage of having two clips ready. 4 stars

They work fine, they load into my spring m14 which isn't by TSD so they work on other m14s as well. Sometimes they shoot all the bbs out while load by hand but a speed loader stops that problem. If you have a spring m14 as a sniper they are a must. i bought 3 of them and i cant complain. 4 stars
