Strike Industries have been expanding their tactical gear and accessories line-up with the release of the MITCH Handguard for the AR-15 platform that can be used for real steel AR and soon can be used also for AEGs (but you may be able to install this on gas blowback airsoft rifles with minimum modifications). This handguard uses their patented polymer formulation which can be installed in a plug and play way without additional tools eliminating the need to replace a barrel nut, front sight post, or buy a low profile gas block.
Costing US$32.00, which is not bad at all for the price and will give other competitors a run for their money, the S.I. MITCH Handguard has optional rails for those who want it, preferring it sold without rails as there are shooters who prefer it that way. What's unique about this product is that it comes with a fin-like multifunctional grip that can act as a foregrip, a finger stop, a vertical grip, or as a magwell extension grip.
