Sons of Liberty L8910.75 Handguard: This innovative product is an improvement from our bestselling M89 handguard, offering superior performance and functionality. Notably, the L89 handguard features a durable Titanium barrel nut and 7-sided M-LOK attachment slots. Plus, it includes two integrated steel QD (limited rotation) sockets and an array of cooling slots strategically located beneath the 12 o\'clock rail, maximizing every bit of mounting space available. Like its predecessor, the L89 employs the trusted M89/Drivelock lockup system but goes a step further to incorporate valuable feedback from end users to enhance utility within modern combative applications. Combining excellent strength, maximum mounting space, and weight-saving materials, the L89 stands as one of the finest fighting handguards available.
