I've owned at least 7 (that I can think of in short order)modern TC rifles with QLA. 3 of the 7 would not shoot conicals worth spit and one of those (an Encore) would not keep conicals inside a 6 foot at 50 yards. Itwouldn't shoot anything else worth a dern either.I never fired a single round from two of those TCs - just sold them - so I don't know if they would have shot well or not.

Knight has far better barrels so far as QC and specimen to specimen consistency.
