The trigger on mine is excellent, the cam locks up good and snug, there is no blow back, and accuracy wise I have no complaints. Its topped with a Nikon Omega and come warmer weather I want to try to see if I can shoot 200 yards with it. I just checked mine since it has been sitting for a few months, and there is no rust anywhere. And I do not see mine as cheaply made.
As for MD's opinion on Remington Rifles.. well all it is would be his opinion. This is the first Remington muzzleloader I have ever owned. So all I base my opinion on it is from my personal experience shooting and owning it.
