I've had it for a few months and done bench, prone, barricade shooting, banged it into nearly everything. Haven't shot 3 gun with it, but I feel confident it will hold up. It was originally tan and I spray bombed it black so it really has alot of character now.
I think it's pretty tough overall and should stand up the the rigors of my weekend warrior range visits.
After crushing the handguard abit, I haven't felt the need to "fill in the gap" yet because it grips the upper rail quite tight.
I should probably get on that sooner than later however...
It's been speculated that these Questar barrels are white oak barrel, rock creek, or mike rock.
To date, I've been trying to burn up my AE 55 gr (a rather fun prospect I might add) at 50, I can hit the small steel (which looks to be about 4"x4" at genessee) offhand, on paper I got some really good groups, a shame I didn't have a phone with me so without proof, I won't commit to anything
With the same 50m zero (and yes, it is exactly 50m from the firing line when I ranged it, good job CHAS/Genessee) I can goto the 100m range and ring the 4"x4" steel plate offhand until my arms give out.
Sitting on the bench, it will hit the steel with with every shot.
Despite it being so front heavy, I love the consistency. Guess I'd better work out more!.
