    USMC M40A1 Return Stock Case Study (The Progression of McMillian Stocks)

    Last four inside the stock: 4359 I posted some of the other markings as well. I was told the SS (Scout Sniper) 172 was in reference to a rack number in the armory. Can anyone verify if this is true? Also what is the significance of the number "13"?

    M40A1 repo mounts and rings

    Out of curiosity, did you or someone you know shoot the rifle and zero both before and after the modification to the mount you describe above? I am curious how much elevation change this modification induces. My thoughts are it should shift POI up significantly, just not sure how far.

    USMC Unertl locking in the parallax on the objective

    Update, scope functions properly now as far as I can tell. Under better lighting magnification it appears the cell was flush with the objective housing when parallax free at 300yds. Also under magnification it appear the focus ring was coming to a stop just short of contact with the objective...

    USMC Unertl locking in the parallax on the objective

    According to the paperwork, he did not open scope up. Checked tracking on a collimator, returned scope to mechanical zero, and set parallax.

    USMC Unertl locking in the parallax on the objective

    The dimple is right about at the 6 o’clock position, maybe a few degrees off. The scope just came back from ironsite, for repair on this exact issue. He’s repaired two other scopes for me in the past and they were great, so I’m not trying to knock his work at all. But when I got the shipping...

    USMC Unertl locking in the parallax on the objective

    Yes, if I push the cell slightly further into the objective housing, I can achieve a clear parallax free image at 300yds. I was contemplating the spacer Idea but after further review it doesn't seem feasible. Other than messing with the objective cell assembly, the only way I can see to fix it...

    USMC Unertl locking in the parallax on the objective

    Correct, the ring is making contact with the end of the scope body. I got the scope from CS Tactical who procured from the CMP.

    USMC Unertl locking in the parallax on the objective

    Yes, sorry. The patent doesn't discuss these threaded rings specifically so I've taken the terminology from other publications. When I am mentioning the "locking ring" i am referring to the outermost ring that requires a spanner wrench to remove. The "focus ring" I am referring to is the second...

    USMC Unertl locking in the parallax on the objective

    With the lense cell against the focus ring, the focus ring CANNOT push the cell far enough into the scope to achieve focus. I just tested this again. The only way to get the scope to achieve focus is to thread the locking ring further out, use the locking ring to push the cell further into the...

    USMC Unertl locking in the parallax on the objective

    Frank, did you ever get this sorted? I have a Unertl (w/ uso mod) that I believe is giving me similar issues, if I understood your post correctly. Problem: The objective lens cell housing that is adjusted (slid forward and backwards by the focus ring) to set the parallax does not come into...

    M40A1 repo mounts and rings

    Has anybody confirmed compatibility of these mounts with the badger ordnance m40a1 Simrad cap? I ask cause the two other mounts I’ve tested were not (TMA and ICE)
