It's a good idea, if you have the gauges, which you don't.
If your bolt and barrel extension are to print you will be fine. Since an AR's headspace is when the "set" when the chamber is reamed, there is nothing you can do to correct it if it's not right...short of swapping bolts and/or barrel assemblies. It's part of the beauty of the Stoner design. I think it's more important to check as the rifle gets used to make sure things haven't worn to much. |

Thanks. I'm getting eager to go shoot and I'm well over budget so my wife is getting touchy about the rifle. I'm a little weary since last deer season my brother loaned me his .246 mag and a box (he didn't mention this part) of reloaded ammo. Round #4 had the case head separate 60% of the way and it blew out the side of the stock just over my right thumb. I'm fairly confident in the gun but I don't want to have a grenade go off in front of my nose. I'm definitely getting a field gauge at the very least as soon as I can. Thanks again.

I'm not an engineer, but I always thought headspacing is necessary if you installed your own barrel. If yours was a factory assembly, it MAY have been headspaced on the assy. floor; or a sever problem would have been found if they test fire each unit- if they do that. Maybe take it to a gunsmith? If you ask nicely maybe you can watch and learn and that should put your concerns to rest. I'm thinking maybe $50.00 for the test, maybe free if you buy something from the guy's shop.

90% of local ranges have head space gages and will check it for free since its a safety issue.
I check mine about 50% of the time. Buy quality parts.. play it smart and use judgment. As stated above.. if it was off you couldn't change it even if you wanted to. |

Well I managed to find a 5.56 field gauge si I'll be holding out until then. My gunsmith wanted $45 to do it once, brownels is charging me 35 with shipping and I can check as much as I like. Better safe than sorry especially when talking about 35,000 psi
Thanks for the input all |

I'd fire a round and check with a Dillon case gage.
Cheaper and you'll probably not even need calipers. |
