Forged Lower HUUCR

Inventory: Out of Stock
Price: $150.00
 

Hard Use Umbrella Corp Receiver. It's how we designate a receiver that might not be the prettiest thing to look at, but it gets the job done like a pro. You don't take these home to momma, you spend a few bucks and use them like the HUUCRs that they are. As Umbrella blems, they may very well look better than other manufacturers' standard parts. These lowers could have some dents, dings, and anodizing issues but it's all cosmetic. Our standard lower receiver specs apply including our patent pending grip chamfer, extreme magwell bevel, our deep laser engraved umbrella logo along with a new surface mark to designate these as HUUCR lowers. Assembly by a qualified Armorer is required.

NOTE: Umbrella Corporation only ships firearms and firearm receivers to FFL dealers. Customers may purchase from the website and have their dealer of choice email a copy of their license directly to FFL@ucwrg.com with the customer's name in the subject line (as a matter of policy we DO NOT accept faxed FFLs). When you create your account or check-out, please enter your contact information/shipping address and not your dealer's. We will only ship your lower to the address of your chosen FFL. Any associated transfer fees assessed by the local dealer are the responsibility of the buyer and not UCWRG. Know the laws of your state or locale: Umbrella will not ship lower receivers to CT, DC, NY, or to restricted cities in CA, IL, MA, or MD. Please contact us directly if you have questions or require clarification.

We do not send out emails to tell you that we have received your dealer’s FFL. That would require hundreds of additional emails on top of those already going out. You will know that we have your dealer’s license when you get the tracking info for your lower receiver. Likewise, if we have an issue or don’t have a FFL from your dealer, we will contact you when we get to that point. And if your dealer is one of those that require a phone call, our license first, or some other such nonsense before they will send us their FFL, please find another dealer.
