    When You Carried One For 8 Months

    Posted by James Hornsey on Mar 27th 2024

    I was a U.S.Marine Rifleman/Radio Operator in Vietnam I 1970. After 3 months we were brought in to a 3 day stand down and the armory people went over our riles. They determined mine to be bad and gave me a brand new Hydra-Matic in a plastic bag. It never had one malfunction my last 9 months there. I got a bug a few years ago to see if it could be recreated. The first time I pulled the trigger a tear ran down my cheek. I'm some of the purists out there would think its ugly. Maybe so it looks like it has been in combat not hanging on a wall. I want to thank Chris for listening to me during a stressful period and helping a dream come true for a 72 year old man. Semper Fi

    Impeccable quality and attention to detail

    Simply the best reproduction retro lowers available. IntMilCo’s attention to detail and quality are the pinnacle of retro items. Totally worth it when only the best will do.

    Awesome receiver

    The receiver is awesome! The MK18 MOD0 engraving is very nice. Like all of their receivers, I recommend this for your next clone build. Thanks Chris!

    Hydramatic M16A1 receiver

    Posted by Jay Phelps on Jan 31st 2024

    This is the second Hydramatic receiver (and I believe, fifth overall) that I have purchased from Intl Mil Co. This one may be my favorite. The grey anodizing looks great. I opted for the Mk 18 Mod 0 "Crane" laser engraving on the RHS of the receiver and that is sharp a precise. IMO, this is the perfect receiver for Mk 18 Mod 0 or Mk 12 builds.

    Nothing but the best. From quality to customer service. Can’t go wrong with an IntMilCo build. The wait is well worth it.
