Overview

The Colt SP64028 is the complete bolt carrier group Colt sells into the commercial channel, and it matters for one reason: issued MK18, SOPMOD Block I and II, and URGI rifles run Colt-supplied carriers. If you are photo-matching a specific reference rifle rather than building in the general style of one, this is the carrier that belongs in it.

Mechanically it is a mil-spec M16-profile carrier group with a chrome-lined carrier bore and gas key, a properly staked gas key, a black parkerized finish, and HPT and MPI testing. It ships complete rather than stripped, and drops into any standard AR-15 or M16-pattern upper chambered in 5.56 NATO, .223 Remington, or .300 Blackout.

One thing to know before ordering: Colt markings vary between production runs. Some carriers show the Colt "C" roll mark with MPC or MPC-2 bolt stamps, others ship with a white dot on the bolt and no external carrier marking. If a specific marking is the point of the purchase, buy from somewhere that will show you the actual unit.

Key Features

  • M16 full-auto profile carrier
  • Chrome-lined carrier bore and gas key
  • Properly staked gas key
  • High pressure tested and magnetic particle inspected
  • Black parkerized finish
  • Complete assembly, not a stripped carrier

Pros

  • +Colt-made, which is the whole point for a photo-matched clone build
  • +Mil-spec M16 profile, chrome-lined carrier and gas key, HPT/MPI tested
  • +Ships complete rather than as a stripped carrier
  • +Correct carrier for MK18, SOPMOD Block I and II, and URGI references

Cons

  • Markings vary by production run, so the C roll mark and MPC bolt stamps are not guaranteed
  • Hard to find
  • Costs more than an equivalent BCM, Daniel Defense, or Toolcraft carrier
