Good choice brother. You can't go wrong with BCM. My midlength has served me well. I've got a lot of misc AR parts laying around if you need anything to complete the build. Let me know.

You guys need to get to an IDPA match down at TAC2 sometime. They had a good match set-up yesterday.

USPSA- first Saturday of every month
IDPA- second Saturday
3-gun- third Saturday
