Colt AR-15 Comp Rifle Kit — Good Option for DIY Gas Gun Build

The Colt Kit does NOT include barrel, bolt carrier group, charging handle, or magazine.

Thinking of building an AR-platform rifle for varmint hunts or PRS Gas Gun Matches? Here is an interesting option from Colt — a value-priced kit with upper, complete lower, handguard, and Magpul stock. To this, add your choice of barrel and optic. We like this option because the barrel is so important to accuracy and overall performance. This Colt package costs $599.99. Add a match-grade, finish-chambered barrel from Criterion or Krieger, plus bolt carrier group, and you’re in business.

There are some very nice features on this Colt Comp Kit. The Magpul PRS stock features a quick-adjustable cheek-piece and butt-plate — allowing you to easily adapt head position and LOP for your discipline of the day. (You may want a different LOP for prone shooting vs. bench shooting). The Magpul stock works well in a rear bag. In addition the handguard comes complete with Picatinny rails on top and on both sides, affording lots of options. We might move one of the rails to the bottom, however, so it could be used for a bipod mount. The upper receiver has an integral Picatinny rail for optics.

We like the Blackhawk grip which is more comfortable than the typical grips supplied by most black rifle makers. The lower includes a trigger group, but you can later upgrade to a Timney, Geissele, or other aftermarket trigger system.

NOTE: This Colt Kit features a Sadlak Low Profile .750 Gas Block and carbine-length gas tube. With longer barrels you may need to adapt a longer tube, but that is an easy change.
