Mine is a 2004 production revolver. Timing and bolt drop are perfect and the trigger pull is light enough for fine target work. The front sight is dovetailed in and can be drifted for windage adjustment. It is also overly tall so that it can be filed down to raise the point of aim to zero.
It is a fine shooting revolver with chamber mouths and groove to grove barrel mesurements at .450" . Accuracy with ball sizes from .451- .457" has been outstanding and it also shoots very well with bullets cast from a 200 grain Lee Conical mould.
Aside from the easily regulated sights, it has required none of the minor adjustments I've come to expect from even the best of the replica revolvers. Very well articulated- it is no more prone to cap fragment tie-ups than the Colt Army. Both revolvers function best with frequent cleaning and lubrication of the cylinder arbor/base pin.
Remington acquired the Beals patent in 1858 and the basic revolver went into production in 1860. This replica is of the New Model as it evolved in 1863. About 130,000 were made up until 1875 with most references saying the bulk were made during the civil war.
