I am assembling my own upper and need to know how/if I should check headspace?
[M16 Bolt Carrier Group Nickel Boron coated and Mil-Spec Hammer Nickel Boron coated. And a Core15 Hardcore Billet Charging Handle V.2] (http://core15rifles.com/products/parts/upper-parts.html?page=shop.product_details&flypage=vmj_color_plus.tpl&product_id=77&category_id=12?) 18" barrel [Noveske 18 Lightweight Stainless Barrel] (http://www.rainierarms.com/?page=shop/detail&product_id=2753) Upper Receiver [Noveske Upper Receiver w/Extended Feed Ramps (M4)] (http://www.rainierarms.com/?page=shop/detail&product_id=2118) |

Checking headspace is a basic safety measure. Especially if any of the parts are used.
It is unlikely that a new bolt and new barrel would be unsafe to fire, but headspace varies when mixing and matching parts. Since headspace is measured from the face of the bolt the true measurement must be made with the bolt the barrel will be used with. Personally I like my new weapons to start out at minimal headspace. YMMV |
