Product DescriptionThe Bravo Company BCM MK2 Recoil Mitigation System Mod 1 T1 is a complete receiver extension and buffer tube kit designed to help reduce felt recoil while maintaining (and improving) overall reliability in AR-pattern rifles. Built around a 4.7 oz T1 buffer with increased internal counterweight travel to reduce bolt bounce, this system also uses an internal spring to minimize counterweight noise and promote consistent weight placement. The kit includes a Mil-Spec M16A4 rifle action spring (with more coils than typical M4 carbine springs) to widen the operating envelope and improve cycling consistency, plus an 8-position MK2 receiver extension for extended adjustability.Product Highlights Complete BCM MK2 recoil mitigation kit for AR-pattern rifle builds and upgrades T1 buffer (approx. 4.7 oz) with increased internal counterweight travel to help reduce bolt bounce Internal buffer spring reduces counterweight rattle and supports consistent weight positioning Mil-Spec M16A4 rifle action spring improves cycling consistency and broadens the operating envelope 8-position MK2 receiver extension provides extended stock adjustabilitySpecs Brand: Bravo Company Manufacturer Part Number: BCM-MK2RMS-M1T1 UPC: 812526023117 Compatibility: AR-15 / AR-pattern rifles (Mil-Spec stock and lower receiver) Buffer Weight: Approx. 4.7 oz (T1) Receiver Extension: MK2, 8-position, Mil-Spec diameter (approx. 3/4" longer than carbine receiver extensions) Material: 7075-T6 aluminum (receiver extension/buffer components as specified) Finish/Color: Hard coat anodized, matte black Kit Includes: T1 buffer, M16A4 rifle action spring, MK2 receiver extension, castle nut, QD end plate Country of Origin: United States of AmericaDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
