bobcat789,

Welcome to Milsurps, The rifle sounds like a standard No4 Mk1 which has the addition of a PHC5 rear sight and target sling loop fitted, two of the basic things for competition shooting with a No4. The Brass shoulder piece is the Butt Plate.

A Sniper rifle was fitted with pads on the left side to the body to mount the bracket and No32 scope. pics of these are in the Knowledge Libraryicon.

Posting pics at first can be daunting, easiest I find is photo bucket or similar, down load the files pics etc, then copy and paste them in your post. Link below may help with pic problems etc.
