Description

This TYPE-A SIPR/18L 450 (STANDARD ISSUE PATROL RIFLE) Complete Upper is built on a accurate Long Rifle platform with proven mil-spec components to make it an incredibly versatile rifle. The SIPR/18L 450 Long Rifle Upper is equipped with a 18″ 416R Stainless Steel barrel (for improved accuracy) and a full 17″ M-LOK– GEN3 handguard with a SILENCERCO ASR muzzle brake to mitigate muzzle rise.  This upper is equipped with a 5 round capacity magazine, proprietary spring and H3 buffer kit (for recoil reduction) making it a complete drop-in package.  The TYPE-A SIPR/18L 450 Upper is once again driven by an EXO Nickel Boron coated bolt incased in a Phosphate Carrier . This UTC EXO coated technology is a patented process that deposits a nickel boron casting onto a metal surface giving that surface a permanent dry-lubricious material that is harder than the underlying substrate. This dry-lubricious surface reduces friction, and dissipates heat so well your parts will run cleaner & cooler without wet lubricate. It’s also equipped with a DGI (direct gas impingement) system for reliability.

NOTE:  All of our rifles are Hardcoat Anodized and then Cerakoted to give you a longer lasting more durable finish.  We wanted your rifle to wear to the anodized surface vs. the raw aluminum surface like some of our competitors.  Just another added benefit making our rifles…TYPE-A.
