M4 ISR Integrally Suppressed Rifle Built around a 9 inch, Cold Hammer Forged S2W profile barrel with a pistol-length gas system calibrated for its integral suppressor. High-performance rifle delivers both subsonic and supersonic projectiles with greatly reduced muzzle blast and flash helping to conceal a shooter s location and keep the user on target with faster follow-up shots and less degradation of vision, particularly in low-light situations. Integral suppressor extends the barrel to the NFA-required 16 inches in length so this platform is not classified as a Short Barreled Rifle (SBR) and only requires one tax stamp (for the suppressor). Suppressor s durable tube is finished with high-temp Cerakote-C, capable of withstanding extreme temperatures under harsh conditions and the user-serviceable baffle core is easily removable for maintenance. Equipped with MFR XL 15.0 handguard which features a continuous 1913 Picatinny top rail and also has Magpul M-LOK attachment points at the 3, 6 and 9 o clock positions. Daniel Defense Buttstock and Pistol Grip. Mil Spec + Cerakote finish. All NFA Rules Apply.
