Getting Hydra-matic….
Did you know General Motors (GM) made M16 rifles for the US Army during the Vietnam war? Here is your chance to own a replica of those made by Runner Runner of Texas. This fully functioning stripped 100% AR-15 lower (FFL required) has the same design as the originals but with modern day AR-15 specs. You can put this on display or you could build into a M16 clone, which is all the rage these days.
Specs:
Semi-auto AR15 lower receiver
Machined from 7075-T6 forged aluminum
Matte black hard-coat anodized Mil 8625 Type 3 Class 2
Works with standard AR15 components and magazines
Completely Mil-Spec; works will all uppers and LPKs
Upper tension screw (uses 1/16” Allen wrench)
Captured take down pin spring/detent with set screw (uses 1/32″ Allen Wrench)
Safety Selector settings: SAFE, FIRE & AUTO
Runner Runner is selling these for $79 here.

I have bought several of this lower They are great but I can not find who make these and the retailer that sold them is out of business. I was told they were made in Texas. Can anyone give some info about the maker. I really want to get some more. Thanks
Matt, Runner Runner Guns in Texas made these reproduction lowers in 2017. They closed shop earlier this year, sorry. Lots of competition in the AR game right now
Thanks for your reply.
Do you know if they made these or just had them made for them buy another factory. I need to get more if there is any way. Thanks Matt
