eForms update

On April 4th, 2014, the ATF disabled the ability for all dealers to file Form 3s and 4s electronically. On June 24th, 2014, the ATF announced the return of ATF Form 1 but stated nothing in regards to the return of Form 3s and 4s to the eForms system. Until more information or an ETA is provided by the ATF, we believe it's in our Texas customers' best interest to file the Form 4 transfer via paper. If you would like us to hold your order until the return of eForms or wait for more information regarding eForms, please contact us. For our non-Texas customers, we will submit your Form 3 via fax, which takes about 30-45 days for approval.

If you are a TX resident, the $200 BATFE transfer fee will automatically be applied after selecting your state of residence during checkout. Non-TX residents will be able to select a transferring FFL/SOT after checkout.
