I recall reading a thread where Trident had modified at UBR to accept a picatinny rail and monopod. I wanted to do something similar with one of my collapsible stocks, so I purchased a LaRue POD for the CTR. While this worked okay, I wasn't necessarily a fan of the CTR's cheek weld, even with LaRue's RISR, so I sought another solution. I thought about grinding and reshaping the bottom of several stocks to fit the POD. This would be easy to acheive with the SOPMOD and STR and could likely work for the IMOD/EMOD. However some compromises would have to be made, e.g., obstructing the QD mounts in the case of the SOPMOD.
Looking at the STR, I noticed a removable plug on the bottom of the stock (buttpad removed). Perhaps Magpul created this for a future add-on product?:

Once removed, I started thinking it would be easy to mount a small picatinny rail in this slot (Note that I filed a tiny bit of the bottom of the STR to flatten/remove the radius):

Thus, I started examining and hacking away at some spare rails. I found a couple of small composite rails that looked like they would work, but they seemed too fragile once screwed in place. The ideal piece for my monopod, the Accu-Shot BT12-QK, was this little guy, the aluminum MI MCTAR-05:

The rail was a bit too long, but was the correct width to fit into the STR. Using a cutoff wheel on a handheld grinder, I shortened the rail by removing the longer portion of the rail near the second fastener hole. I also found a suitable backing plate that came from Magpul's MOE accessory rails.

Once cut, the rail fit into the STR in a very secure manner. I've angled the backing plate to ensure more area comes into contact with internal ribbing in the stock. I may fabricate a larger backing plate if necessary, but it appears to be very secure as is:

I still have to test this modification, but it seems very stout and secure.
