IRREGULAR DEFENSE X NOVESKE CHAINSAW 11.5" SBR 5.56 - FDE

The Noveske Chainsaw Irregular Defense 11.5 SBR is a premium short-barreled rifle built for suppressor-ready performance, precision reliability and hard-use tactical applications. Developed in collaboration with Irregular Defense, this complete rifle combines Noveske’s proven engineering with purpose-built ergonomic upgrades and premium components throughout the entire platform.

At the heart of the rifle is an 11.5-inch 5.56 NATO barrel manufactured from 416R stainless steel with a 1:7 twist rate, hand-polished Noveske Match Chamber and serialized QC tracking. The barrel features straight fluting, extended feed ramps and a pinned low-profile gas block paired with a mid-length gas system for exceptionally smooth cycling and reliable suppressed performance.

The forged 7075-T6 Chainsaw™ upper and lower receivers are finished with Type III hardcoat anodizing and FDE Cerakote® for maximum durability and corrosion resistance. The rifle includes a Noveske FDE Love Handle ambidextrous charging handle, full-auto compatible bolt carrier group and CGS SCI-SIX flash hider/suppressor mount.

A 4th Generation NSR-10.75” free-float M-LOK handguard provides optimized suppressor clearance and extensive accessory compatibility. The rifle is further enhanced with premium B5 Systems and Irregular Defense furniture including a FEER stock riser, Special K grip, MHS hand stop, MRC rail covers and MBS barricade stop.

The lower receiver features a Geissele SSA-E two-stage trigger, H2 buffer system and precision fitment enhancements, creating a highly refined SBR platform designed for demanding shooters and suppressor-focused setups.
