Doing an AR Build and got this barrel from Wilson Combat (I'm a sucker for a sale): https://shopwilsoncombat.com/BARREL-556-NATO-RECON-16-FLUTED-STAINLESS-GLASS-BEAD-1-8/productinfo/TR-556RCIG16FT8/
16", 5.56 Nato, .750 Journal, with a 13.25" intermediate gas tube.
I measure the gas port at .092". Good to go?
Thanks for increasing my paranoia. 🙂
Just getting back to this build. The BA Hanson barrel (link) has a midlength gas port, which according to the chart on this page should be 0.078 or .081. Using my pin gages I get .070 which is what's shown for a carbine-length system. I've already got the Armalite tube and a HeavyBuffer for it. Is it worth testing as-is or should I just drill it? It's often weeks between range trips, unfortunately.
Yeah - after blindly just buying factory AR15s for decades, my limited AR10 build experience has taught me to not trust anything from anyone ever. To be fair that's not a stretch for me, but it was eye-opening to say the least.
I've built two (mostly) Wilson Combat .308 ARs and on the second one the barrel would close on a no-go gauge - with two Wilson Combat BCGs! Thread about it here. They took it back no problem, but my perception of "buy it all from WC so it will work right" is gone. On the first build I had all sorts of problems, too.
I guess my point is that I don't have much confidence that a WC BCG is needed for a WC barrel.
Just an update that I finally got back to the range with the finished rifle along with its XH 8.5oz heavy buffer in its Armalite tube and it is an absolute female cat-cat of a rifle now! It's not quite "watch the target through the scope while firing" smooth, but it's only an 18" barrel and a muzzle brake would solve that. I had a couple of friends along and they both commented on how freaking smooth it was.
You guys fucking rock.
Just wanted to update that I sent the barrel back to WC and requested a refund with the explanation that it closed on a no-go gauge.
No argument, no drama - just a refund notice in my email. That's... kind of great.
You have no idea how much I'd love to go down the suppressor route, but here behind enemy lines our benevolent dictator dickhead governor won't allow a flash-hider let alone a can.
