I have owned three of the R25 rilfes, all in .308 Win. They were all excellent for accuracy, and one was consistently MOA or better with a wide variety of factory .308 ammo, 125 gr to 200 gr.
The original hammer springs were TOO LIGHT for reliable detonation of hard primer 7.62 military ammo, so they were replaced.
One rifle got an Armalite AR 10 three way adjustable trigger, one got a 2 lb JARD single stage [ MAJOR pain in the butt to install ] and one got a decent 5 lb pull after I worked over the stock parts.
I sold my aluminum DPMS mags and used the plastic P-mags exclusively. Absolutely no failures to feed with the pmags and all ammo from 125 to 200 gr.
I sold all of my Rem R25s and replaced them with a DPMS LR308B. The LR308B comes with an 18" HEAVY barrel, and unfortunately they moved the gas port back to carbine length with this one. Which has resulted in some OVERGASSING with certain brands of hi performance ammo. I find the NOSLER 168 gr Match ammo, which is labeled at 100 fps faster than 168 GR federal GMM, to be a bit too hot. Primers are cratered, brass gets indented with the extractor cut, etc. I will probably/eventually fit an adjustable gas block on this one.
Accuracy is SUPERB. With factory .308 Win ammo, and the HORRIBLE trigger, Sub-MOA is quite do able. A better trigger would definitely yield better consistency.
However, so far the 7.62 NATO accuracy is not so good. 3" with LCM BALL. Hoping to get better than that with Hirtenberger, if i can ever find some.
All in all, the Rem R25 is a heav, FUGLY CAMOED version of the DPMS LR308B. But the rifle length gas port location sure makes for a more versatile, reliable, and forgiving system.
