History[edit | edit source]
Design[edit | edit source]
The AR-57 uses the straight blowback, rather than a gas-tube system. It also has an extractor disposed of in a lower and an ejector disposed of in an upper, this was made for the upper work well with the 5.7 cartridges.
Trivia[edit | edit source]
Wikipedia cites that the rifle is used by Canada, however, this could be a confusion of a Canadian forum. No real info or reliable sources have proved that Canada used this.
