Description
The Dirty Bird 20″ .22-250 Complete Upper is a great building block for your next tack driver build! .22-250 is a high-velocity round that is not only incredibly accurate but also has very low recoil. The lightweight Dirty Bird .22-250 complete upper is great for medium-long target shooting and for hunting those pesky varmints!
Built on a top-tier Forged Upper Receiver and finished with Dirty Bird’s 17.5″ AR-10 High-Profile SMRS M-LOK Handguard. No corners are cut when manufacturing these complete uppers. All barrels are dimpled and cold blued, use a black nitride 4140 steel gas block and a stainless steel gas tube. The gas block set screws feature knurled cone tops and are installed using blue locktite ensuring that no amount of firing will cause the set screws to come loose but they will still able to be removed for servicing if needed.
