JSD Supply Polymer 80 Build Kits

Before May 2022, JSD Supply sold Polymer 80 Build Kits to the public. These build kits contained an 80% completed frame. 

80% lowers are legal in Federal law. Purchasing a P80 build kit is fully Federally legal. However, there are some controversies between manufacturers and the Federal government as to what constitutes an 80% build kit.

JSD Supply’s Polymer 80 build kits are currently unavailable pending the outcome of their lawsuit against the BATFE. This is an expected outcome with the potential for a judgment that could set legal parameters regarding the 80% rule

JSD Supply Binary Triggers

JSD Supply push-release triggers are industry-standard trigger devices that allow the shooter to fire once on the pull and once on the release of the trigger. With push-release triggers, you can double your rate of fire, completely legally.

The National Firearms Act of 1933 (NFA) defines a machine gun as a weapon that fires multiple rounds on a single trigger action. 

Push-release triggers fire only on the pull and only on the release. Because of this, they do not meet the NFA definition of a machine gun and are legal without expensive, time-consuming NFA paperwork.

JSD Supply Shipping

JSD Supply ships to any location within the 50 states. Credit card processors require shipping to be to the customer’s billing address, so keep this in mind when ordering.

All shipping is USPS Priority Mail and is weight-based. JSD requires signatures for high purchases to protect customers from fraud and theft.

Return policy is a strong point for JSD supply. Their return policies are best-in-class. JSD Supply promises returns on unaltered and unused products and encourages people wanting to process a return to file an RMA with the company.

JSD Supply ATF Raid

On May 11, 2020, the Bureau of Alcohol, Tobacco, Firearms & Explosives executed a warrant at JSD, which JSD Supply fought in court.

The Cease & Desist order was rescinded on May 24, and a lawsuit was filed in Federal court against BATFE on August 24, 2022. That suit is ongoing currently.

JSD wants to reassure people that there was no actual “raid.” There was no Hollywood drama. ATF delivered a cease and desist letter and JSD responded appropriately. 

Some pages and services normally seen on JSD Supply’s website have been disabled because of the lawsuit. JSD is hoping to return to full operation soon.

JSD has an active gun show schedule in the fall and winter of 2022. They are showing across Pennsylvania for the remaining weeks of the year.
