A "lot" of folks swear by Mobil 1 - I've used Amsoil (auto application) synthetic for years and have over 200K on an F-150 - off subject - but I have not tried it on my guns. I have used Weapon Shield which "is" a synthetic and supposedly very invasive into the molecular structure, etc... I know that I get no rust at all, cleaning is quick but I've not done this on home hardware. Good ideas Dusty. OF note on the R-25 and overall grittiness and feed of 'BCG' and charging handle... there seems to be a LOT of play upon pulling the handle fully out (up and down play seems greater than in my other AR types) and I see that "mechanics" can really cause some sluggishness and grabbing when racking the slide. If you do not keep it in line perfectly it will grab/grind and grate making it seem like there are smoothness issues but really it is mechanics. It would be nice if the 'channels' for the handle were supporting all the way out of the BCG tunnel. Take care...

Understand. Good idea... I only have a AR15 bolt so not compatible ... I put a beefed up handle on mine as the stock on the R-25 was smallish and with optics on hard to reach... but even heavy duty does not make it nice and I am still working on "smooth."

So the bolt 'does not' move or move well in the carrier? Or is it the carrier just not sliding well with the handle? My new R-25's bolt is certainly more snug in the carrier than my 16 but I can still move it by hand and remove the pin/rotate bolt, etc... I use a "grease" on my bolt/bolt carrier contact points but might try a thinner lube.

First post, great forum... I just rec'd my R-25 Rem / DPMS in .308. Aside from not loving the Camo the price was 'very very' good and so I bit. I was pleased to hear of others having issues with BCG and function because mine was so hard to open that at first I was looking for some release pin or something totally weird and new... nope. Just super sticky/gritty. Two hands and foot gritty. I took out the carrier and did some very careful polishing of the contact rails and tested. Took three or four passes with a felt, compound and 1000 grit wheel and finally I can pull it back left handed. However the charging handle is still very gritty. I think there is Camo 'overspray' making it rough. Initially this AR had trigger (not mine) problems that were talked about in forums but mine is VERY smooth and breaks at 4+ to 5#... and again, smooth. I did lube some areas wtihin the group but I am happy with that pull. The R-25 has been observed out to 1000 yds on steel, hits. It is accurate but I've not fired mine yet. Called DPMS about some other parts issues and they were helpful. They made the R-25 for Rem. and aside from the very gritty issues it seems like a fine AR. Will post after first use at range (the 1000 yard confirmed was with two friends who have the R-25 in same caliber, etc)
