Echo1 USA is soon to come out with the new AR-57. History on the AR-57 or AR Five-Seven is that it’s based on a real steel caliber conversion that changes the standard M4/AR15 from 5.56mm NATO to intermediate 5.7x28mm round and magazines. The AR-57 has the same great feel as an M4 but due to the smaller cartridge, it also offers extremely low recoil and high ammo capacity over the standard M4. The 5.7mm round has high lethality and armor defeating capability even up to 200 yards, making it a great personnel defense weapon.

The airsoft version faithfully recreates this gun in every detail, and will come fully licensed and engraved with AR Five Seven Trademarks. At its heart is the metal monolithic upper receiver which holds the 5.7mm style magazine.

The upper receiver has long continuous rails running along the sides and under the barrel. Its short overall length and collapsible stock make this a great CQB weapon. The AR-57 is a completely unique design that should stand out from the crowd of other M4s that are out on the market today.

  1. Its not just for show… actually if you grab an m4 mag or ar mag and hallow it out, thats where the 5.7 rounds eject and the mag acts as a catch can to make clean up alot easier.

  2. I'm very doubtful about this. The P90 already has problems with gravity feeding, did E-1 find a way around this, or will AR-57 owners still have the same frustrating problems as with their P90s?

  3. tbh, the guys putting the mag in the ar-57's magwell are pretty dumb. the magwell was there as a shell ejecting port which (if you haven't noticed) doesn't exist on the side of the receiver. blocking the magwell (which is the shell ejecting port) is useless in airsoft but in the real rifle, the mag will overheat and probably be… wait for it… ~too hot to handle~ "badum tss" ;).

  4. Dear echo1:
    I like this project a lot, and I love seeing company's being very creative. True it will be awkward at first but I can see this being a deadly field rifle bwahaha. But I have a questing, has echo1 company considered making an AEP (airsoft electric pistol)? I have a cyma p226 as a side arm, but Id much prefer sticking with echo1 like I have with all my main rifles. Don't get me wrong, the timberwolf is beautiful, however gas is not readily available in my area. So any thoughts?
