The quick lock time is probably the single biggest reason for good accuracy, that and pretty darn good barrels for a rifle that cost less than $100 when introduced.
I have two of them in 22-250 and for whatever reason, those bbls are substantially heavier than either the M788 222 or 243 barrels are.
Was tempted to buy a new one in 7mm-08 back when they came out, but never did get around to it. Liked the idea of that stubby barrel for a handy deer rifle.
