BTE makes a good adjustable gas block and not expensive.
Works well on my Liberty barrel that many sent back to be scraped but mine is a tack driver shooting 123 SST's into half inch groups with 27.7 grains AR-comp at factory COL of 2.245.
Getting 2520 fps average with 18 inch barrel.
I did a lot of polishing with JB's and flitz and handloaded a little short during barrel break in to shoot the 123's at factory length.
They're right on the lands but no pressure problems.
I would think all the liberty barrels that had issues have been converted to what they call G2 by now.
Barrel and bolt cost me 230 bucks.
I got a 16 inch 264LBC with the light contour from BHW for around 280 shipped.
Not much difference in accuracy but had to wait around 2 months to get it.
Shoots any bullet at about any COL real good and the poly barrel was so smooth I didn't bother with any barrel break in methods.
Easiest barrel I've seen to clean and never fouls with copper build up at all.
