Thanks for the feed back...

Picked up a RRA flat top upper w/bcg has railed front block w/removable A2 front sight and has removable rear A2 sight, 9mm buffer, cproducts mag block, and 4 cproducts 32rd mags.
I don't have a 9mm hammer but read that you can modify the hammer so it runs and I read a bunch on ramped bolts....so I might look into that as weel.
I should get it all next week so hopefully the weather is good so I can take it out......then I'll know if anything needs tweaking or not.

Thanks again....
