    Spike's Tactical .22LR Upper Lightweight Pencil Barrel [STU2100-M4S]  $699.95 
     
    box_bg_l.gif.

    Spike's Tactical .22LR Upper Lightweight Pencil Barrel -

     

    It's Finally Here, The Lightweight ST-22!

    Upper Specs-

    - Forged Mil-Spec M4 flat top upper receiver w/Mil-Spec Type III hardcoat finish

    - 16" GM 1x16 Twist Chromoly Barrel, Lightweight profile under the handguard w/Carbine length sight radius

    - M4 handguards w/Round handguard cap

    - F-Marked A2 front sight post

    - A2 birdcage flash hider

    - Spike's Tactical Dedicated .22lr bolt

    - Forged Mil-Spec charging handle

     

    **FYI: The legal 16" barrel goes inside the receiver approximately 1.5" so the barrel looks like a true military 14.5" length. The barrel also comes with the end threaded 1/2 x 28.

    This upper utilizes the correct 1:16 twist rate for the .22lr bullet and eliminates the problem of fouling AR15 gas tubes with dirty rimfire ammunition.  All of our uppers come standard with Match Quality Green Mountain barrels.

     

     

    Regarding the Spike's Tactical .22lr bolt. Our bolt is based on the Atchison design with improvements including the following: an electroless nickel finish gives it a much slicker, smoother finish so you do not have to run it as wet which means the bolt stays cleaner longer. We have changed some tolerances, beefed up the firing pin and pre-drilled for a ball-detent.
    We test fire and tune all of the dedicated uppers in house with Federal bulk red-pack but some of the dedicated uppers may require tuning for your setup or ammo, un-notched hammers (aka Sporter) also work best with them. Most all full-auto's will require tuning and hot ammo. We recommend running a suppressor on a barrel length shorter than 10".

     **Uppers do NOT come with a Magazine** CMMG mags may be added as an option below.
