Should You Install a New Bolt w/This Barrel? Some of our customers have suggested that we should include a new bolt with our AR15 barrels. THEY say you should install a new bolt anytime you install a new barrel on an AR15 platform. On the other hand WE'RE trying to keep costs down and if you already have a good bolt, there's no sense in adding the cost of another one if you don't need it. So, if you want to add a new bolt to your barrel order, you can select "Yes" to add one for an extra charge. Our Nickel Boron bolts are excellent and reasonably priced!
