Description

Please Note: Given the current demand for this product and supply shortages, your order may ship with a black hammer and trigger or a stainless steel hammer and trigger.

A mil-spec M4 Gov barrel paired with a lightweight M-Lok free-float.

This M-Lok-equipped, Government-profile AR15 kit is the perfect build choice for a lightweight, compact, accurate shooter. The 4150 CMV barrel’s been finished with a Nitride QPQ finish to improve barrel and rifling life without sacrificing accuracy. 

The skeletonized M-Lok handguard provides a Picatinny rail for a flip-up front sight, ditching the main rail to shave serious weight, coming in at around 7.5 ounces. Everything else is mil-spec: M4 upper with feed ramps, M16 BCG, mil-spec parts kit, and an M4 buttstock.
