We have heard about the AGM M4A1 Gas Blowback rifle as being in stock at Gunner Airsoft. Now, we have another version of this low-cost GBB rifle alternative coming with RAS rails at eBaybanned. So those who are turned off by the classic M4A1 look as lacking in rails to attach further accessories such as foregrip, tactical torches and laser, can go for the RAS version. It has rail covers and is priced at US$178.00 inclusive of shipping costs.
