Frequently Asked Questions

What tools are needed to install the SB Tactical HBPDW brace?

You will need a vice, a vice block (like the Midwest Industries Block), a 3/4-inch driver or wrench for the buffer tube, and the included castle nut tool. A hex wrench is also used for final torque on the castle nut.

Does the SB Tactical HBPDW brace use a standard AR-15 buffer and spring?

No, the SB Tactical HBPDW brace utilizes a shorter buffer and spring compared to standard AR-15 setups, which contributes to its overall compact design when collapsed.

What is the purpose of the castle nut tool included with the HBPDW brace?

The castle nut tool is specifically designed to help thread the castle nut onto the buffer tube, which can be recessed and difficult to access with standard tools.

Should Loctite be used when installing the buffer tube for the HBPDW brace?

While Loctite is provided and mentioned in the instructions, the instructor in the video advises against using it on the buffer tube's connection to the receiver, based on personal experience.
