INTL.MIL.CO - M4/M4A1/M16A4 LPK - Lower Parts Kit 

New USGI M16A2/A4 Selector

  • Black Colt Anodized mag button & Trigger Guard
  • NEW M16A2 USGI Selectors (M16A1 & A2 Grey/Blk LPK avail in Rarities)
    • Schmid M16A2 Selectors just like what Colt used/uses still
  • Triggers (NEW) - We supply two different triggers 
    • Schmid Semi Auto USGI GI trigger
      • Same MFR trigger the Pony company has used since 1980
    • Schmid two stage trigger with a 2 lb pull and 2.5lb break, more info soon
  • 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 - 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
  • UPS Ground

    M4 LPK - Black Phosphate

    Another great lower parts kit from IntlMilCo. Everything is what I expect and want from a GI-type LPK, especially the safety selector and magazine release button. Plus, the XM177E2 sticker thrown in was something that I was going to purchase anyway, but forgot to add to my cart. I’ll try one with the 2 stage trigger next time!

    Great parts kit, all components are exactly as described. Had a shipping issue during the holiday rush, however communication was prompt and courteous and problem was solved immediately.
