The Action Army AAC 21 is based off the M700 Remington with a metallic CNC Aluminium body. It's a gas sniper rifle with a very smooth bolt action and doesn't even require you to pull the bolt back all the way to pull the BB forward.
On the top is a monolithic upper rail sitting along a rail system allowing for a lot of additional rails for all your accessory needs. Unfortunately, you'll need to buy them separately. At the back is a M4 collapsible crane stock and an ergonomic pistol grip with space inside for spare parts.
It is based off the Tanaka M700 series so you can expect it to be very accurate and very powerful as it clocks in at a consistent 440 feet per second. There is a gap to reach the safety but it is still pretty difficult to reach especially if you're wearing gloves, but if you are wearing fingerless gloves, it shouldn't be much of an issue.
As a gas sniper rifle clocking in at 440 fps with consistent accuracy at only 375$ which is an amazing deal!
