A:Hi Jerome and welcome. I would check with Sig Customer Service directly at 603-610-3000 and then press 1. Sounds like an easy fix would be an angled or vertical handgrip. Cheers and stay safe! -

A:Zach, Bud's will not ship this gun to WA, it is prohibited. The pistol grip, adjustable stock, threaded barrel, muzzle device, and barrel shroud are all prohibited in WA.See 2 more answers |

If you order a gun that is WA compliant, Bud's will remove any non-compliant magazines. -

- Asked 05/25/2022 22:48 by Mark E H
A:Mark, this will be fine for both left and right handed shooters. This has ambidextrous controls. So as long as the gas is set properly it'll throw the spent casing out at the 3:30-4 o'clock position. So a left handed shooter won't have any problem with this rifle. Hope this helps.See 1 more answer | -

- Asked 07/22/2019 17:50 by Brian B
A:No due to the fact that it has a detachable magazine plus a telescoping stock, pistol grip, flash hider, and threaded barrel. The magazine capacity is also too large, must be under 10. https://www.budsgunshop.com/catalog/feeds/state_reg/new_jersey_restrictions.pdfSee 3 more answers | - Show More Questions
