What are the two most popular methods when applying for a SBR stamp?


Trust is a legal entity and as such can legally own assets. One of the most popular methods for getting a NFA stamp is using a trust for a couple reasons. Depending on the trust you select and it’s legal language the process of inheritance of NFA items can be considerably easier. A trust can provide the ability for the control to move to another person without actual ownership the of the item changing. Another benefit if you select a trust with the ability to add/remove co-trustees is you can allow other individuals to posses the same NFA items without you present.

I recently had a chance to try out the BAD-MRO lightweight optic mount for the Trijicon Miniature Rifle Optic (MRO), an absolute co-witness mount, and I was very impressed with its machining, quality look and feel typical of the products made by the premier firearms design and manufacturer, Battle Arms Development, Inc.

The BAD-MRO is one of the lightest available mounts for the MRO, weighing only 0.78 ounces including two cross bolts. In comparison comparable mounts from SLR Rifleworks and AXTS Weapons are 1.2 ounces and 2.05 ounces respectively. But don’t let its weight fool you, the BAD-MRO is precision machined from solid billet 7075-T6 Aluminum. Its single-piece design allows it to be lightweight and rigid and the same time. Its hard coat black anodizing is smooth, clean, and beautiful for the shrewd and very discerning eye.

The BAD-EMMR is a lightweight, low profile, modular magazine release for the AR-15 and AR-10, recently released by Battle Arms Development. Its expanded finger pad provides an enlarged, uninterrupted, contact surface that gives the user a positive tactile feedback resulting in fumble-free operation.  One of its outstanding features is its modular design, allowing its users to use an array of finger pads depending on personal preference or operation. The EMMR’s 3-sided, precision fit, solid, dovetail attachment interface simplifies its locking mechanism – a feature that makes it stand out from the rest of its competitors. This translates to a wiggle-free, tight tolerance, slop-free fitting between the magazine release body and finger pad. The dovetail attachment interface also removes the stress away from the screw; this allows a single, scaled down, set screw to be used as opposed to the typical two large steel screws.
