Saltworks Recoilless Battle Rifle And UBSG Kit

We at Saltworks have Noticed a seeming lack of Practical Recoilless Rifles.
So we did our best to Solve that Issue. Though what with us just being a small Collection Gunsmith's.
We didn't go too Crazy with the whole design.........well thats a lie we always go crazy....why should we not.

Operated in the same style and Manner as a Normal Rifle.
It's Large bulk is made up for by the fact that it has almost no Recoil.....or at least it has the equivalent of a Airsoft-Gun.
The Action itself goes far back into the Stock reducing most of the Recoil.
Having Built in Sights in such a way allowing for the Use of most any optic the user wants.
The External Barrel Slides back and forth on the inner barrel taking in most of the Barrel Shock and Muzzle Drift.
And the Mag Lock and release mechanism is so Snap tightish that there is no way to yank out the Mag accidentally.
The Round Used is yet to be Disclosed to the Public same as the amount of rounds held by the Mag.

The UBSG or under barrel Shotgun Kit.
Is another idea we had is to remake the Master Key.
Using a Custom Gauge Sizes and Sound Suppressor and a Special round called the Scalpel Shot.
A Removable Sliding Stock and Removable Rail System and sights.
All allow this little Mod to be fitted on the Bottom Rail of most any large gun or to be used as a real quiet Shotgun.

Together This makes a Sweet "Little" package for any Front line Type or any other type of Soldier or Warrior really.
This being a Prototype it does not have the Company Logo or anyone signature.

(As always i'd love some feedback on this on what i could Improve or Should Change)
