I need some help on building a ar-15 in 40 S&W. Not interested in hearing from 40 haters. I have several pistols in 40 S@W and am sitting on a shit load of bullets, Brass, powder and primers. I have built several ar-15 rifles in 5.56. Now I want to build one in .40 S&W. Any pointers, suppliers, parts. Anybody here built one or have one that could give me pointers, pro vs cons. Thank in advance. MDSHOOTERS is the best!
