Looks like it has no full length top rail, and no front sight on the gas tube. That means you are forced to either get a full length rail installed or only use an electronic or optic sight.
They've got enough rail to mount a scope.
And $175 more than a comparable PSA and $30 more than a comparaple S&W M&P sport.
I picked the QRC because of its ultralight barrel.
Who has the S&W for under $488? Bud is asking $611 for them.
