Looking for an 80% lower jig for AR-15s. Looking for one to be used with standard lowers, no polymer. Would like if it came with an 80% lower but not a must. Hoping maybe someone has a used one they've finished a lower on and are now looking to get rid of it. Willing to buy or trade some items for it. For trade I have a new set of dual comm MSA Sordins, BNIB Bushnell Elite 1500 rangefinder, BNIB Hogue Automatic Combat Knife, BNIB Bates Combat Boots (Size 10R), or new Altama Coyote Boots (Size 10). Thanks
