INTL.MIL.CO M16A1 & M16A2 Lower Parts Kit

20 or so 1960's GM Hydra-Matic & Harrigton & Richardson Bolt Catches will be in stock again October 2022 

 We will do a Grey H&R Specific LPK with H&R Selector and Bolt Catch (Works for GM Too)

Last time we had 50 pieces, this time it will be 20 FYI... 

FAQ answered below & Many photos

   If you choose a M16A1 selector they are 60's/70's used/take off parts and parked finish will be slighly worn.    -   John Thomas @ Retro Arms Works can reparkerize if you want them to look new. To keep orders flowing we will be not doing any park work right now.  

  • Black or Grey mag button & triggerguard
    • Grey Mag buttons are new Colt but freshly finished, they wil look correct 
    • Triggerguards are new freshly finished
  • Used takeoff M16A1 Selectors, New M16A2 Selectors w/Tic (Auto Selectors) or Modern Semi Auto Selectors
    • The A1 Selectors are original Vietnam Take off, most are 1964-68 Colt, some are H&R
    • M16A1 Selectors would be correct for MK12 & MK18 mod 0 builds
    • M16A1 Selectors will be used w/wear, John Thomas @ Retro Arms Works can Reparkerize for you!
  • Triggers are optional - These are the finest standard semi auto triggers available
    • ALL LPKs will include parkerized trigger pins - this is often the overlooked part in guns
  • All steel parts are GREY Manganese Phosphated (Look at the last photo) - Not Nitride or Black oxide/Black like most modern lpk's now days 
    • 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's highest grade parts, the same parts Colt uses
    • Most LPK include imported pins/bolt catches, nitride or black oxide coated. They work fine, they dont "look" correct and are not the same quality
    • Schmid offers milspec parts AND commercial/value parts, these are the milspec parts just like the ones used on M4A1
  • Grips are optional
    • Colt A2 "Fat" grips and Schmid USA A4 Grip (Modern A4/Military Colt/FN Style)
    • None
  • Priority Shipping or UPS Ground

    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.
