    • Manganese Phosphated steel parts have been the standard since the 601 
    • They are oiled to prevent rust while stored so they will look dark when you receive them - Acetone will make them grey again. I just wipe off the face of pins/bolt catch/mag catch etc.
    • All the pins/bolt catch are just like the ones found in M16A1
  • Schmid Tool USA - the same parts Colt uses - USGI Grade 
    • Most LPK include imported parts, usually nitride or black oxide coated. They work fine, they dont "look" correct and are not the same quality

    The LPK looks fantastic. I'm excited to install it into a Intl. Mil. Co. lower soon enough here.

    Recommended Business!

    Posted by Jon on Jul 4th 2023

    Ordered this for my H&R retro build. After wiping the pieces down with acetone, they turned a nice grey color. Extremely satisfied with the quality of the LPK. After the initial confirmation email upon purchase, didn’t receive any communication. I inquired about the status of the order around 2 weeks after purchase, and I was promptly given an update - seller was very responsive and I received the shipment not long after. Highly recommend doing business with INTL MIL CO.

    10/10 Would Buy Again

    Posted by Hunter on May 10th 2023

    I read many great reviews about INTL MIL CO online and decided to go with the A1 LPK from them. Great customer service all around and all the parts were just what I needed to finish up my retro build. And I got cool stickers so thats a bonus.

    Highest Quality Retro Lower Parts Kit

    Posted by Charles S. on May 28th 2022

    I purchased two sets of these kits, and the quality is amazing. Installation of kit was easy, roll pins are high quality and did not mushroom like I have seen other kits do. Springs are strong and secure, phosphate parkerization matches receiver very well. Trigger pull is crisp. Very happy with this kit, all correct retro style to complement these M16A1 receivers.
