Not to pry, but what range of prices would this run one interested in going this route to form a trust? Thanks.    Edit: NM, I see its $250 from a quick Google.

Thanks Teecro. You are right and that's what I gather. I see that people just contact the manufacturer and send parts back if it isnt correct.    I read elsewhere that a gunsmith charges $10 for a go-no go check, then again that is for 5.56. I'm building a 300 blackout, so chances are less they have them on hand.    Also, I think the issue is rather apparent if it's too little...meaning the bolt won't close. However, the danger appears to be if there is too much headspace and with a closed bolt, I wouldn't be able to tell that. Hence the need for the gauges.   I think I just need to gather a list of gunsmiths and see who has the gauge and how much to check.

I am in the process of building a 300 blackout. Got my premium BCG from PSA and will probably be using a 10.5 barrel from MAS Defense.    My question comes when thinking whether to buy the headspace gauges or not. I would just as well buy the gauges except they want $100+ for all three. Or I would just bring it to a gunsmith if it were fairly reasonable.    But the things I read are all over the place. Some people say they have built tons of AR and never once checked it. Some people say they have issues right off the bat for brand new stuff and took it up with manufacturer after checking headspace. Anyone know how much a gunsmith charges for checking headspace on a bare bolt and barrel? Thanks guys.   Any other thoughts are welcome.
