PlaSSo shows his ongoing project of converting an Academy Airsoft M416 (HK416) AEG into an AR-57 AEG. This conversion allows him to use the P90 AEG magazine on this AEG. It is just a project, but if you are interested in one, there are already AR57 AEGs in the market. Where? Just ask your friendly airsoft retailer near you.
eHobby Asia announce that they have in stock the S&T ST-57 AEG which is their take of the AR-57 for the airsoft market... "The AR-57, also known as the AR Five-seven, is an upper receiver for the AR-15/M16 rifle lower receiver, firing FN 5.7×28mm rounds from standard FN P90 magazines.
Something to look forward to from Echo1 USA and this AR-57 might just make it on time fo the Summer Season when the airsoft season will be in full swing... "Echo1 is soon coming out with the new AR-57. History on the AR-57 or AR Five-Seven is that it’s based on a real steal caliber conversion that changes the standard M4/AR15 from 5.56mm NATO to intermediate 5.7x28mm round and magazines.
