Limited run. Ok gamers. You want the ultimate do-it all SBR upper? I couldn't possibly have found a better match for our 12.19" barrels - the Riflespeed RS7524 with the Breek Arms 11.7" handguard and Unrivaled Low-Signature Device pair together at the muzzle like they were meant to be. You get it all: tool-less gas adjustability, built-in HUB compatibility with no adapter required, amazing recoil control without the concussion and flash of a competition brake, and maximum handguard space for keeping the most comfortable grip and attaching whatever accessories you like.
This upper is designed for shooters like me who have severe INDECISION and can't seem to stick with a configuration for more than a couple range sessions. The Unrivaled LSD (Low-Signature Device) is both amazing at taming recoil and has excellent performance as a HUB suppressor adapter, allowing you to change the purpose of your rifle on a whim. The Riflespeed 7524 gas control knob has exactly the right amount of accessibility while maintaining handguard real estate, allowing you to change out BCGs, buffer weights, suppressor types, or go loud, and allows you to dial in your exact gas setting for the situation.
QBKs are nearly-complete upper receiver groups designed to shortcut the effort it takes to get you to your dream build. We handle the more tedious portions of assembly.
This QBK includes the upper receiver with a Method Ordnance Standard 12.1" barrel, Riflespeed adjustable gas block and Riflespeed gas tube, Breek Arms 11.7" rail, and Unrivaled Low-Signature Device (LSD) muzzle device pre-installed and timed. This QBK is built with a mil-spec upper receiver with forward assist and ejection port installed.
Simply add a compatible bolt carrier group and your selected charging handle. A charging handle is not included unless selected above. Bolt carrier group is not included.
The 12.1" mid-length is the compact workhorse. It eclipses the 11.5" industry standard because it's a practical SBR length that preserves useful handguard real estate, runs smoothly when suppressed with minimal gas blowback, and retains just enough velocity to make heavy match loads useful at distance. In other words, it's more flexible, comfortable, and practical than an 11.5", while filling exactly the same role with zero downside.
All QBKs come with the accessories and manuals included from the individual parts used during assembly.
