.223 / 5.56 / Wylde Head Space gauge needed

[Rightwinger]

Anyone in the Sumner Co/ Wilson Co/ Rutherford Co area want to make a little back on their purchase and let me check my build out by borrowing your go / no go gauges?  How about some .22?

 

The TGO CMT build is about to come to final assembly.

No need to check headspace if the barrel extension is already in place, at least not with 99% of the companies out there.

 

What barrel manufacturer did you buy from?

[Rightwinger]

Manufacturer unknown Dolomite.  That's the only part that bothers me.  States made in USA.  It's marked .223 Wylde, 1/8 twist but no manufacturer marks.  Snugs up super tight in the CMT upper and sized brass goes in with a "snick" but that's the only test I have been able to do.  Everything I've read says 99% of quality barrels will be fine, I just figured a 30 second test before I put the gas tube and forearm on would give me peace of mind.

 

I got it off Ebay, came from Alabama.  Guy has 100% positive feedback or I wouldn't have gone there.

My first upper assembly.  Plenty of lowers and changing out hand guards but this is the first one where I'm installing the barrel.  Don't want to mess up the TGO/CMT upper!

Then I have to get the muzzle brake timed on it.  These must be fairly new.  I'll post up a pic of the build when I get it all done.  Still waiting on vice block to arrive.

The headspace is set at the factory. The ONLY time you need to set the headspace on an AR barrel is if you are the one putting the barrel extension on. You would have to do some serious searching to find an AR barrel that is being sold without an extension installed.

 

Timing a muzzle brake is not an issue. Install a crush washer then tighten until it is where you want it.
