Strike Industries AR Mega Fins Key-Mod Handguard Rail

    Strike Industries have done it again with another ridiculously low priced accessory. The new AR Mega Fins handguard costs $99 for 7″ / 9″ / 10″ lengths and $130 for the 11″ / 12″ / 12.5″ / 15″ lengths. It has a slim design and is described by the company as feather weight (7”: 5 oz 9”:5.8 oz 10”6.4 oz 11”: 7 oz 12”: 7.6 oz 12.5”: 8oz 15”: 9oz).



    The name “Mega Fins” is derived from its design which has internal fins to draw heat away from the barrel/chamber and into the handguard. This has the significant advantage of keeping the action cooler and reducing the chance of cook-offs or other thermal failures, but the tradeoff is that the handguard will heat up quicker. Like with other lightweight slim metal handguard, sustained fire will require the use of gloves. We still have not figured out how to circumvent the first law of thermodynamics 😉



    The Mega Fin has a top picatinny rail and seven keymod rails at 45-degree angles. Ridges run the length of the rail for better grip. A barrel nut tool is included with each rail.
