SRS scope rail mounting

[The Harbor Master]

Installing an SRS 20moa scope mount on a T3X. The mount comes with 4 bolts, but 5 holes for those bolts (to correspond with the 5 threaded holes in the receiver), though pics online show the rail having just 4 holes. Does anyone have input on which 4 holes to use, or does it not matter? Am I totally missing something and the 5th hole in the rail is for something different altogether?

I did send message to @Salmon River Solutions a couple days ago, but understand it may take a bit for a response and I'll be taking this rifle out tomorrow for some testing.

I believe the extra hole is for original T3’s.

That was my suspicion... it does seem like all 5 holes in the rail correlate to holes in the t3x receiver though. Unless I am confusing recoil pin holes with threaded holes. I did post this after a few whiskeys with the neighbors so I might be off.

Just checked, there are indeed 5 threaded holes in the t3x receiver. I guess you just pick 4 and run with it.

As Form said, we did just add the 5th so the rail works with a T3.

So, maybe a dumb question…but since there are 5 holes in the rail and 5 plastic plugs in the receiver but only 4 mounting screws, do you recommend removing the 5th plastic plug or leaving it in so there isn’t a hole that goes all the way through to the bolt?

Also, the recoil lugs are tight enough that they require tapping in with a hammer. If I ever want to take this rail off, will the recoil lugs come out? There’s obviously no way to punch them through from the other side.
