Frequently Asked Questions

What tools are needed to install the JAKL rear adapter on an AR-15 lower?

You will need a flat head screwdriver for the initial installation of the threaded adapter and a 5/32 inch Allen wrench to tighten the 10-32 flat head screw. Blue Loctite is also recommended.

How does the JAKL platform differ from a standard AR-15 regarding the buffer system?

The JAKL platform features an internal buffer system located within the upper receiver, eliminating the need for an external buffer tube and spring assembly typically found on the rear of an AR-15 lower receiver.

What adhesive is recommended for securing the JAKL rear adapter components?

Palmetto State Armory recommends using Blue Loctite on both the threaded adapter and the 10-32 flat head screw. This helps prevent the components from loosening due to firearm operation.

Can any AR-15 lower receiver be used with the JAKL upper?

Yes, with the installation of the JAKL-specific rear adapter components onto a standard AR-15 Mil-Spec lower receiver, it becomes compatible with the JAKL upper receiver system.
