Looking to sell or trade sig spear with 13” barrel. This is a pistol so you can form 1 to Sbr it if you want to go that route. Purchased from extreme guns and ammo in Richardson 3 months ago and purchased the stock adapter separately from sig. I have 10 rounds through the rifle. It’s a bad ass rifle, but I’ll stick to 5.56. 6 mags and 250 rounds of ammo will be included. Looking for a Kac sr15 or an LMT in 5.56. Text 9Othree Two 27 OO42
