I like the Gun Parts Corp. scope better than I do the RSM that I have. The GPC scope looks identical and has the same reticle as an original MKI or MKII scope. The RSM reticle is way too "fat" and the main body machining leaves much to be desired.
My Mk II scope came in today from Gun Parts Corp. . When I compare it to my l42A1 and No4 Mk1 sniper rifles It looks very good indeed . Very clear view and the cross wire and post is not heavy . the steel tube is nicely made and is blued not raw steel painted . the front sun shield has the correct small flat head screw holding it to the main tube .There is the same screw positioned on the rear locking the ring the holds the lens into the large bell of the scope . The serial number is 1944 No. 17565. I will install it on my scope less l42A1 that I picked up from Navy Arms in 1990's .
RSM is making the MK3 version ...
Also the rsm mk2 is a real 1 moa click...All other repros are 2moa (like the mk1)
RSM is asking $500.00 for the MkIII and $100.00 shipping . The Gun Parts Corp. MkII is currently selling for $261.00 with free shipping and looks very nice and works .
I too just received a MkII from Gun Parts Corp, and it looks like a decent quality reproduction. I do however believe that I have an issue with mine (unless I am completely missing something here). Once mounted into a reproduction No 4T mount on my No 4 T rifle the reticle is canted counter clockwise by about 5 to 7 degrees, which is very noticeable. I have been reading all of the mounting and adjusting instructions and am to this point under the assumption that there is no adjustment for this since the scope has the small peg screw that locates into the slot on the mount. Im quickly thinking I may have gotten a defective one. Anyone else seen anything similar on these?

Your mount has a recessed area at the bottom of the front ring this is for the scope's dowel locating pin . this will have to be enlarged from the center line of the recess right and left this will allow you to cant the scope to center your scope cross hair and post . Also be aware of the fit of the scope in the front ring ,most of the after market scope mounts including the ones made by RSM are way out of specification and when the rings are fitted they will bind in the scopes area to receive the rings .If it dose you have to shave the face and the rear of the rings to insure there is no binding .I had a original No 32 MkI scope the would not a line the post and cross wire unless the after market mount was reworked as stated above . Never remove metal from the scope . Remove metal from the mount it is the lest expansive item and if you make mistake it is ease to replace.

Thanks for the information here. So did you have a similar issue with the cant of your scope? I can hold the scope so that the turrets look level and clearly see the reticle is not rotated to align with them. I have no idea who made the repro mount I have as it came with my No 4 T rifle, but can you tell me what is considered the best repro one to use?
