High Tower Armory 90/22 is a compact, maneuverable stock kit for the Ruger® 10/22® which utilizes a bullpup design for superior balance and ergonomics. This incredibly durable, polymer stock will reduce the overall length of most 10/22®’s to about 26 1/2 inches, just over the federally required minimum length for rifles. The HTA 90/22 also features a CNC machined monolithic aluminum Picatinny optics rail and aluminum bedding block, as well as an ambidextrous steel charging handle which cycles the factory 10/22® bolt from forward positions. The HTA 90/22 trigger linkage is made of Melonite treated steel for the most consistent and efficient transfer of energy, having a resistance to flex three times greater than aluminum by weight. A safety extension is included to allow the original factory safety to be activated, in addition to a safety selector located near the trigger. Also included is both an extended magazine and automatic bolt release which replace the factory releases and allow for much faster manipulation of your rifle's controls. This kit comes complete with a removable dummy suppressor, two side mounted Picatinny rails, and a detachable ammunition storage box for holding spare rounds in the field. Accepts factory 10 round magazines as well as most aftermarket high capacity magazines. Fits factory 18 1/2" and .920" bull barrels at least 18 inches in length (17 1/4 inches from receiver face to muzzle). Made in the USA.
