Right!

if the carrier is dragging on the gas tube it'll act like undergassing, so making sure the tube to key alignment is correct. not only that, but making sure the hole in the block is @ 100% over the port and most likely not against the shoulder of the journal (usually has a gap).

Thank you for taking the time to contact us! In our testing, we used a standard mil-spec carbine spring and 3.0oz carbine buffer. We were also using a full mass bolt carrier group.

We have noted that there is a fairly stark difference between the three loadings that Hornady offers for 22 ARC. The 62gr ELD-VT loading can be a bit undergassed in a gun that is otherwise perfect with the 75gr or 88gr loadings.

You may also want to check both the gas block and the gas key on the bolt carrier for any signs of a leak in the system. This could be robbing some energy and slowing the cyclic rate of the rifle.

Sounds political

Review post #10…

That is exactly what Faxon is telling you.

Get it cycling with your lighter weights and put an adjustable block to choke down for heavier and/or suppressor.

Should be able to work that out easily.
I'm sure it'll be a blast when you get her humming along!
Best of luck!

I don't recall you mentioning whether you were using a 55gr or an 88gr. bullet loading.
