We are working on 20 receivers to list in June/July - Sign up for our news letter @ enter email to be notified, this gives us a running list of people waiting

PRICE Stays Same - We are charging for UPS 2nd Day Air now - USPS is too unreliable - We are looking at ways to reduce cost FYI

I DO NOT OWN COLT MARKINGS - Colt offers beautiful Retro M16s - The XM16E1 and GAU-5/A/A will be out soon!

I DO NOT SELL HR MARKED LOWERS ANYMORE - Nodak/PSA has teamed up to offer real HR lowers/rifles... I will not change existing orders to HR, stamp 80%s w/HR, however I will sell correct style uppers for these for a short period

Each lower is guaranteed form major defects however we do not have warranties on lower receivers. Any issues that come up will be approached on case by case basis.

    M16A1 GM receiver

    Posted by Ari T. on Jan 31st 2022

    The fit and finish is excellent! The detail that has been put into these is outstanding. The roll stamping add visual and tactile elements lacking from the engraved receivers out there. The anodizing is the perfect early grey shade. There is even forging flash in the right places. If you're building clone correct rifles, or in need of a receiver to go with a surplus parts kit, this is the only way to go!
