We know your curious, so lets answer those essential questions.

WHAT?

• Built In Recoil Unit
• Adjustable FPS 
• Adjustable RPS
• Only 1 moving part

The Atomic-Engine is a new, HPA/Green Gas compatable firing system designed, and built fully In-House. Capable of 50+ RPS and tunable FPS, its a forced to be reckoned with at its production cost of only $20.

HOW?

Reduced down to just 1 moving part, the atomic engine cuts out all the possible failure points in any other replica, no gears, no cut-off lever, no extras. During all of our reductions, we kept every drop of performance inside. With tunable FPS and RPS (Via the included firing blocks), This engine can be made to work on any type of field or firing range. 

Oh, and did we mention the recoil? The only moving part in our firing engine is to provide the shooter with further realism, The AtomicEngine comes equipped with a blowback piston built inside, This includes an automatic firing cut-off when out of rounds (At the expense of no further moving parts), no firing without a magazine, and a small size, allowing for almost any replica built with it to be 1:1.

WHY?

Us here at AllenAirsoft are collectors ourselves, and we wanted to keep realism in the picture for those who appreciate it. The AtomicEngine is what we always wished we had. Field-ability in a compact, reliable engine. The AtomicEngine is affordable and allows us to produce our own, collector grade replicas cheaper than importing them form Japan.

WHERE?

The AtomicEngine is not V2 compatible, or compatible with any other company for that matter. It was designed by us, for use in our own custom guns. It can be found in our newly launched MPK
