The clamp-on style of handguard attachment, utilized by many manufacturers is both secure and convenient but one problem has always been that clamping the handguard it tends to lift the front end of the handguard. The longer the handguard, the more drastic the effect. If you've ever had to bottom-out the front-sight post of a rail mounted BUIS in order to get the correct elevation, the issue is probably due to this ""lift"" phenomena.BarrelChambered in 5.56 (will also function with .223)16a ^2" Government Profile w/ 1:7 TwistMid-Length Gas SystemQPQ Nitride FinishHigh Pressure Tested and Magnetic Particle InspectedSub-MOA GuaranteeDirty Bird Enhanced Bolt Carrier GroupStrategically relocated load bearing surfaces reduce carrier tilt/can't during recoil, thus increasing reliability and longevity.Additional wall thickness in the gas exhaust port area for added strength and rigidity.HandguardPatented ASAL (Anti-Slip, Anti-Lift) mounting system6061-T6 AluminiumType 3 Hard Coat Anodizing1018 Steel Barrel NutASAL Attachment SystemQD Attachment PointsUpper ReceiverPrecision Machined from Top Tier 7075-T6 Aluminum Forgings (forge marks may vary)Not all forged uppers are created equal and we only use the best for our uppers meaning they will be free from excessive pitting, machined to spec and finished with quality (not purple or chalky) hard coat anodizingM4 FeedrampsForge Markings may varyMay or may not have T-Marks*Includes mil-spec charging handle Made in the USA - Backed by Dirty Bird Industries' Limited Lifetime Warranty
