These are numbers matching kits.

The barrel is a new barrel made in our own shop that is a different profile on the end of the barrel so you can put any 14-1lh muzzle brake on the barrel.  Bore is .214 with 1-8 twist and made from 4150 steel.

These kits come with the bipod, cleaning kit, oil bottle, stripper clips and cleaning rod.

Parts kits come with items pictured, but some demilled receiver pieces may not be included since not every one had them included when we received them.

Keep in mind these kits are sold as is as far as furniture and finish are concerned. 

Ok, now that that is done here is what we've done...

All journals are measured as well as the parts to be pressed to make sure the fit is correct.  We set the headspace and check it twice with a GO gauge, with a live round (not fired just for testing the bolt closing) then with a NO-GO gauge.  After setting the headspace we drill the barrel pin hole and ream for the new barrel pin.  The pin is pressed most of the way through so you can press it back out the same way it was put in to remove the barrel for installing rivets.  If you don't want to use rivets then just press the barrel pin the rest of the way in.

The rear sight, gas block and front sight are pressed on after the barrel pin is installed to make sure everything fits correctly on the barrel.  We use a special fixture to press on each piece to ensure proper alignment.

When reinstalling the barrel I reccommend to use a headspace gauge again to make sure you install it back to the original setting.
