RRA LAR-8 TRO-MID Free Float Rail, Mid-Length

TRO - Top Rail Octagonal. Extended mid-length, requires the use of a low profile gas block. Hard coat anodized 6061 aluminum. Complete with all necessary mounting hardware. Installation requires some gunsmithing. Length: 11.5 inches. Weight: 15.4 ounces. Includes one MID and two Short Accessory Rails. NOTE: RRA LAR-8 handguards are for use only on the RRA LAR-8. The RRA LAR-8 uses a unique receiver thread length and barrel nut. No barrel nut (either separate or as part of a tubular handguard or quad rail handguard) except those made specifically for the RRA LAR-8 should ever be used on an RRA LAR-8 rifle or upper half. While some other barrel nuts may thread onto the RRA LAR-8 upper receiver, the depth of thread is incorrect. The use of a barrel nut not specifically made for use with the RRA LAR-8 (and identified as such by RRA) may expose the shooter to risk of injury or death.
