Prototype for QUICK RELEASE buttstock for the Lockhart Tactical UBS-12 under barrel 12ga shotgun.
When not needed under your primary firearm, quick detach the under barrel shotgun and quick attach the light weight aluminum buttstock.
We'll also have a quick attach optic mount that will HOLD zero! Making our unit an incredible dual purpose firearm.
Points to note:
1) not shown in picture, but a limb saver buttstock pad will come installed to help reduce felt recoil
2) clamp on breaching muzzle break tips will be avail
3) buttock features our own system for quick release and fast attach
4) not shown yet, but an optics mount will quick attach and detach which will hold optical zero
5) all of our parts are made here in Canada
6) will be available in BLACK anodized or colored cerekote
7) pistol grip will be moved forward to mate as close to trigger guard as possible
We're open to suggestions on how to make our final buttstock look.

We're thinking of either making the buttstock look more minimalist by removing the 30 degree bracing arm, and also adding an optics rail clamp in a safe place.
This clamp would be used to attach the optics rail for storage when your UBS is under barrel mounted.
To clarify, the attachment clamps on the TOP of the UBS (where it attaches to the primary rifle), is where our special optics rail will seat when the UBS has the buttstock attach in its Micro Combat Shotgun Configuration.
The optics mount will be designed and made in a way that it sits in the locking lugs of the UBS-12 QR clamps to ensure the optic holds zero time after time when removing and replacing your optic. Storing the optic on the buttstock, ensures you can't lose your optic and it's ready for immediate attachment.
