Wellllll now,
I just happen to have an R25,
and I'll have to disagree with a few of the previous statements.
1.] the finish on my R25 is NOT "durable" ....
ON THE PICATINNY RAIL, WHERE I'VE MOUNTED AND REMOVED SCOPE RINGS A FEW TIMES, THE FINISH CHIPPED/FLAKED OFF. YOU CAN LITERALLY SCRAPE THIS PAINT OFF WITH A FINGERNAIL. NEVER MIND THE VERY VISIBLE CHIPS, NICKS AND SCRAPES YOU GET FROM NORMAL HANDLING aka SAFE KISSES.
2.] The paint is THICK, and changes the fit of some components. I tried to use max diameter match trigger/hammer pins, which fit fine in all my other AR 15 receivers, and the pins were too big to fit into the holes in the R25. I had problems fitting an RRA match trigger set, but no problems fitting a DPMS match trigger set [ with the RRA set, the bolt seemed to catch on the hammer when cocking ].
3.] I am thinking about stripping the upper and lower, bead blasting or using some type of chemical paint remover, and refinishing with dura coat, in my own favorite camo pattern,r simply re-anodising
But I would definitely recommend stripping off the old paint before adding a new finish.
4.] I will warn you that the DPMS built for Remington R25s ARE NOTORIOUS for ABSOLUTELY HORRIBLE trigger pulls. My R25 had the worse trigger I've ever felt on an AR [ and I've felt LOTS of AR triggers in my time ]. Set your budget to include a DPMS or other aftermarket match trigger. The funny thing is, in other genuine DPMS AR 10s, the triggers don't seem to be as bad??? Maybe DPMS sends their factory second trigger parts to Remington??? Also, the R25 hammer spring is bent to lighten the trigger pull, which co-incidentally, also lightens ther hammer fall. If you get failures to go bang with your factory DPMS hammer spring, swap it out for an ordinary AR 15 hammer spring.
Personally, while I liked the DPMS match trigger I installed, eventually I switched back to a standard AR trigger ... after I gave it bit of polishing to achieve a decent trigger pull. But my R25 trigger is still not as sweet as the RRA match trigger in my AR 15.
5.] I've owned about three dozen of the ORIGINAL, AI built AR 10s, and was waiting for one of the modern AR 10 clone builders to come out with one that was as reliable and durable as the originals. For the money, I think the R25 is the best "bang for the buck" in a modern AR 10 clone. Obviously, using as many AR 15 parts as possible in an AR 10 MUST create some design compromises, but with the R25, at least it seems like they didn't compromise reliability.
these are just my personal opinions,
YPMMV,
and remember,
opinions you get for free on the internet may be worth much less than you paid for them.
