My buddy wants to build an AR pistol using an Aero M4E1 lower. I know it’s just a roll mark, but it has the nice built in trigger guard (looks better than Anderson’s curved guard) and the bolt catch release pin is an allen screw for a punchless LPG install. Yes I recommended that specific lower.  I’ll be helping them install the LPK this weekend up at their place in Iowa, but just need to help them find the lower.  They live about half way between Council Bluffs and Des Moines. If someone knows a dealer who might have that SPECIFIC lower in stock in either of those cities please let me know.

Brownells in Grinnnel, IA has the AERO PRECISION - AR-15 M4E1 STRIPPED LOWER RECEIVERS 5.56MM in stock.  It's right off the interstate 80, about an hour east of Des Moines.

You can order it online today for pickup so they are ready when you get there.

Yep. One stop shop and generally the best price locally.

Found one.  Thanks for the info.  Will be helping them install the LPK tomorrow.

Hit me up if you need one in the future. I'm in Nevada.
