Brownells USA Fantastic Kit! 12/02/2012

So there is no confusion what you are getting, here are the part numbers. It coems with the nice MetalForm magazine (part # 620-000-021) and the mag block is part # 100-000-920. I used these in a Post 86 full-auto and they are going great! Not a single hickup. The only other part you will need for your lower is a 9mm bolt catch (part# 160-308-101). This will allow you to retain the bolt hold open feature.

For the money, this is a fantactic kit. If it runs flawlessly in my full-auto, it will be just fine in semi-auto only configurations.

The reason this gets 4 stars, rather than 5, is the bolt catch should just be included in the kit.
