We've removed them for now.
Any new applications should use the EZTUNE tubes.

I have a 14" BRT build I did that's gassed quite nicely for unsuppressed use. Lately I find myself running it suppressed full time, which leaves it a little gassier than I'd like, (though still very smooth functioning). I ended up messaging with Clint, and ordering an EZTUNE gas tube, which cuts the gas down considerably. It still cycles and locks back with M855 and 55gr commercial spec ammo, but cut down the gas to the face when suppressed. Shooting this and then shooting commercial ARs leaves me sad for people, lol. Very happy with the simplicity of it.
- cqbdriverIt is from the construction of underground FEMA camps. I can't say more because there a guy parked in front of house in an AMC Pacer. He is acting like he talking on the phone, but I know better.
I have to sign off now & put my laptop in the microwave.
Absolutely. The big takeaway for me is that buddies with overgassed rifles can fix that without chasing crazy spring/buffer combos, and put their money towards a better rifle. My M&P15 back in the day was cycling a Sprinco extra power spring/H2 combo with gas to spare. I could have thrown one of these in and just started on my next rifle...
Took my 10.5 Noveske out with a .0625 EZ tube since my Q Thunder Chicken was approved. Functioned with and without can running A5H3 shooting M193. Everything worked as I had hoped.
Clint took care of this issue for me, but my insert got pushed up into the tube. The drill bit provided basically fit my CA gas block so in went the insert. After firing maybe 40 rounds it got pushed up into the gas tube pretty much shutting down the rifle. Clint switched it out with an EZ tube and it has run fine since.
To do it right with an insert IMO would require a true threaded hole for the insert to screw into, slightly larger than the one he provided.
