Two products released by Magpul USA last September starting with the MOE Midlength Hanguard and the Angled Fore Grip Version 2. Please do take note that this items are released by Magpul USA and not by Magpul PTS, their Hong Kong based airsoft and training division. This may fit some existing M4 gas blowback rifles and rails made for them without modifications but check first or wait until Magpul PTS releases the airsoft version.

Available in dark earth which you can get at RedWolf Airsoft... "Rugged ABS plastic G27 grip is contoured and comfortable for use on your M4 Gas blowback rifle. This is a replica of the TDi Arms G27 grip. Comes with mounting screw. Compartment in grip can be accessed by opening bottom cover, allowing you to store batteries and other emergency tools in there."

Not to be really excited about it, but the X-Player Transformable Metal Foregrip at Airsoft Panda is configurable to different lengths to suit your preferences. If can just unscrew or screw on some of its modular parts until you get the most comfortable length you want. Besides, surprise your mates which would wonder if how many X-Player foregrips you have, not knowing it's only a single item.

Check this one out at UK Tactical... "Flashlight Grip Adapter combines a 1"-1.08" adjustable light mount and vertical grip in one. Thumb activated push button on grip operates lights on/off switch. Removable side plates utilize a rubber surface to enable installation of a pressure switch underneath side plate. Lightweight and very robust, this is a high quality product, fits most standard picatinny rails, can be fitted to SA80 rail system.

Whistler Peng of Star Rainbow Company (SRC) just sent in news of their newly released tactical foregrip and according to Buckshot, it seems pretty standard besides the fact that it got a small rail on the side that looks suitable for a Laser or a Flashlight. The front grip also uses the fiber reinforced nylon material that SRC now makes all the plastic parts to AEG's of. It is a VERY durable and strong material. Real Steel manufacturers use the same material.

Evolution Tactical, a Canadian Airsoft and Paintball equipment retailer has posted online their RIS Foregrip Xenon Tactical Light with QD Mount. It is a high quality tactical RIS mounted weapon light with Quick-Detach mounting. Powered by 3x CR123A lithium batteries, this tactical light produces 250 lumens of blinding light power and weighs only 505g with batteries.  The light weight does not interfere with the manuevarability of your weapon, reducing the weight on the front end.
