SR25 Upper Compatibility

[the monk]

I guess if we ask, we shall receive. Centurion Arms is selling SR25 slanted upper receivers - https://centurionarms.com/mk11-7-62-billet-upper-receiver/

nice! Now if they can make a chrome BCG for the large frames. I speculate they're working on it.

Anybody by chance have a picture of the updated Centurion MK 11 with a Knights lower? Was wanting to see how the lines match up.

I’ll get you one later this evening if no one beats me to it.

In summary the front pin won’t go in on either SR25 upper without a slight reaming. On one LMT lower the pin goes on partially, on another it will seat but with a fair amount of resistance. Lines don’t look bad but there is a slight gap. I’ll run with it for now.

This is my finished Troy on LMT lower:

Thank you for the excellent pictures and write up. Looks like I may try to either get one of the HTX uppers when they are released again or just do the whole Centurion upper and lower.

You are welcome! Glad they were helpful.

Do your pins go in easy on that upper?
I had a lead on some Troy uppers but it looks like they fit about the same as the Centurions.

Needed some tapping when new. I think the surface anodizing inside the upper holes needed just a little polishing.
