I received my new XM15 E2S V Match Carbine Rifle a few weeks ago and had it taken into Fulton Armory (the closest gunsmith in my area) to have a Weaver Rail gas block and bi-pod stud installed.
While in the shop the owner runs it through safety tests after doing the requested work on the rifle. Upon completion of the inspection I was told the following:
"... the headspace closes on a no/go gage..." and "...the headspace is longer than it should be..." "...shooting low-grade ammo through this could be dangerous..." "...could cause case separation..."
Obviously, I am pretty concerned at this point, since I haven't even taken it out to the range, I am now going to be worried that the rifle may blow up in my face.
This is troubling considering I just purchased this rifle. Please let me know what steps need to be taken to resolve this problem.
Could you give me a little insight as to what I should do from here?
Should I send it back?
Is it supposed to be like this?
Is this a common problem?
Why wasn't it caught before sending it out of the factory?
