Universal Compatibility Guarantee
If you find that a Modulus Arms jig is incompatible with your metal 80% AR-15/AR-308 lower, please send both the Modulus Arms Jig and the incompatible lower back to Modulus Arms. Modulus Arms will modify your jig to fit to your lower, and return everything to you at Modulus Arms' expense. If the jig cannot be modified to fit your metal lower, Modulus Arms will return your lower at Modulus Arms' expense, along with a full cash refund. This guarantee applies on three conditions:
- The Modulus Arm Jig shows no signs of use.
- The received billet or forged lower must have been deemed by the ATF as a non-firearm, and be unaltered from that form in any way.
- The unaltered lower must be compatible with standard AR-15 or AR-308 upper receivers.
If all three above conditions are not met, the Modulus Arms Jig and lower will be returned at the owner's expense. Modulus Arms will immediately dispose of any lower receivers that Modulus Arms, in its sole discretion, deems to have been altered from its original form.
If you need to return an item under the Universal Compatibility Guarantee, simply email email@example.com. Be sure to include your original order number and a brief synopsis of the incompatibility issues you encountered. We will respond with instructions on how to proceed.
