Serial Number 1911 SBR

Inventory: Out of Stock
Price: $3500.00

We don't often present complete rifles for sale to the public, and when we have it's only been for charity. However, for 2020 we thought we might offer a one-off rifle every quarter or so, starting with this sweet little SBR. The plan is to create something unique, either due to a T&E or prototype component, a desirable serial number, or an interesting combination of rare parts. For this short barrel, we started with a Gen 4 forged lower, serial 1911, mated to a Gen 3 forged upper. A second generation Umbrella BCG rides in the upper, and a short, V7 300 BLK barrel is surrounded by a Daniel Defense MFR XL rail. It ships with a Gemtech inert 300BLK suppressor that's included strictly for display purposes only; Gemtech strongly advises against shooting these mock cans! Please note; the V7 barrel is extremely short at 6.5". We chose this length so that a suppressor would fit inside the DD handguard with minimal protrusion. No muzzle device was installed leaving the buyer free to select his own attachment type, or stay with bare threads. However, before shooting with a suppressor, especially subsonic ammunition, you must consult with a qualified gunsmith or armorer to ensure concentricity between barrel bore and suppressor. Umbrella will not be responsible for any potential baffle strikes as we are neither the manufacturer of the barrel, nor the supplier of the suppressor. We intended to offer this short barrel in Q1 but the current madness delayed that a bit. The result is that we have two SBRs available in Q2; the more the merrier we say.

Umbrella Corporation only ships firearms and firearm receivers to FFL/NFA dealers.

When you create your account or check-out, please enter your contact information/shipping address and not your dealer's. There are specific fields now for FFL transfer information and we will only ship your lower or firearm to the address of your chosen FFL.
