I could not be more pleased with my CDI Bottom Metal kit... I shot my second match with it this past Sunday and the more I shoot it the better I like it. It just right for 10 round mags, I need to order a couple 5 rounders and some more 10 rounders but they have not been back in stock. I think its a good choice. Id buy again.
If you find 10's in stock and think about it give me a heads up. I have a few 5's but need to grab a 10.
