If you are running a pistol caliber AR you might want to get on the notification list for the new Side Charging Upper coming soon from Quarter Circle 10. Pics and details are below. These are not in-stock yet but you can enter your email in the “Get Notified” box at www.QuarterCircle10.com.
Our upper features a non-reciprocating charging handle. This allows the operator to remain in the firing position while charging the firearm. You can easily pull the charging handle to the rear and active the bolt catch with one hand in one motion. This upper was designed around mil-spec standard and will accept any of our blow back bolt assemblies. This upper has an enlarged ejection port and will fire pistol calibers from 9mm to .45 ACP. Our upper has a trap door in the rear to keep dirt out of the upper and allow easy removal of the bolt from the receiver.
