  • Extra Necessary Items

    Texas residents will need to pay sales tax of 8.25% on merchandise total excluding freight.

    Use of credit cards incur a 3% fee against total bill (freight included.)

    If purchased locally, the buyer will need to follow all current ATF rules. I am a current FFL holder. No buying without a background check unless you are a holder of a CHL or LTC. No third party sales. No trades.

    If shipped, the firearm must be shipped to a current FFL holder. After payment is made, have your local FFL email a copy of their license to admin@mjrweapons.com. Shipment will be done immediately after receipt of FFL and funds clear.

    All warranties go back to the original manufacturer. Refunds will be made only if an item is misrepresented or description is misleading to the average gun owner. Return shipment costs are incurred by the buyer unless prior approval.

    I honor a 3-day inspection policy. The time starts from the receipt by your FFL. If the weapon is sold as new and has been fired by you or your representative, the inspection period is considered to have been honored.

    I prefer payment by PayPal. This protects all parties.

    Shipping charges are $25.00 for handguns and $40.00 for long guns.  No shipping to California, New York, New Jersey or any other state where the weapon is not legal.  You, the buyer, need to know what is legal in your state and what the local firearms law are.
