So, after a bit over 13 months, I finally got my Ultr-7 in .264/6.5mm out of jail.
This morning I took the Hellfire brake off of the gun, installed the Area 419 mount on the Ultra-7 (there was already an uni adapter on the end of the barrel), and slid a Griffin Armaments .260 alignment rod down the bore. This is on a Bartlein MTU barrel spun by Ern at Altus (who seems to do absolutely fabulous work).
Now, these uni adapters and the 419 mount for TBAC were bough at approximately the same time that
@GBMaryland had bought his. Aug of 2021.
Below is a pic of the alignment and its perfect. Note that the rod is .004" under the bore diameter of .264 so the VERY small bit of droop toward the bottom is a result of that and if you flip the gun over it goes the other way. Its wonderful
Clearly Area 419 does not have an endemic issue with these mounts, a couple of exceptions seemingly notwithstanding. That and they told us that they reviewed their CNC config, fixed up something or other, and inspected remaining mounts in stock.
So, in my opinion, shooters should buy these items from 419 with the same very high degree of confidence in quality that we have always had with 419 products. I do love the handful of items I have gotten from 419 and expect to continue to do so....even if I am "myopic and premature" haha
However, I do think this whole thread speaks to the importance of having an alignment rod to check suppressor fit. Compared to the cost of a potentially damaged suppressor, they are cheap.
