R5 mil-spec
Let me as a remington employee, and owner of a R5 clarify a few things for you. I know for fact that
the barrels on the R5 are not rock's barrels the first few for the military contract M24 sniper rifles
were, until we could tool up or equipment to produce our own R5 rifling. The barrels are not military
barrels that did not pass our quality checks either, any barrels that we produce that are not exactly to
tolerance are imediatly marked with red dykum and sent to the barrel bender. The gun however is a
limited production non-cataloged 1/4MOA firearm. And unless you want to pay for a M24 about $3.5K and get
a gun that shoots just the same as a R5. Now for all of you who think that the R5 is just another
factory produced gun with a marketing plan you got another thing coming, now the R5 is not a custom gun
but we put alot of pride and tradition into each firearm we produce and the R5 is no exception in the least.
I have time and again at local matches put them $5k customs to shame, and I garantee you that the difference
between a 700 sendaro and an R5 is quite astounding. Or you could just come up to Illion and find out
the hard way lol. So in closing boys and girls the R5 is a very exceptional weapon that i would put up
against any custom out there.
P.S. you will not wear out the SS any faster that normal carbon steel.

What does it mean when a barrel is said to be a "5R"?5R is the form of rifling I developed for use in most target barrels and in many sporting barrels.
These barrels have 5 grooves, and the lands have angular sides. I have observed that bullet jackets
will deform such that they remain closer to the R-form lands than they will to the sharp-edged
lands present in conventional-style rifling. This reduces powder fouling at the corners of the
grooves. The angled form of the lands also helps to reduce jacket failures in quick-twist barrels.
Your results are only as good as the worst of the three.
....Mother of god.
...Bending a hammer forged barrel to make it straight is an admission of their mass-produced quality control. He does not mention stress relieving after such "improvement".
...
I believe sent to the bender means they are destroyed not straightened.
As for the accuracy. I haven't seen one yet that won't shoot sub .5 moa with 168 federal gold. I have seen people continue to refuse to try this ammo and only use their handloads or cheaper ammo. In which case is it the rifle or the ammo?
As for the inherent accuracy. I believe the twist rate of 1:11.25 plays a large part. Probably more so than the 5r aspect. It's ideal for 168 and 175. How many rifles can you get off the shelf with this twist rate? Most are 1:12 or 1:10. The Tikka which is also touted as very accurate out of the box I recall has a 1:11 twist rate. My Canadian military AR10 which shoots the same ammo as the 5r is almost as accurate. Guess what. 1:11.25 twist rate and 24" barrel just like the 5r.
Think what you want about the 5r. The ones I've shot when using Federal gold match shoots like a custom tactical rifle. The ones that don't shoot are the exception. Before blaming the rifle I would want to rule out, ammo, optics and the shooter.
The results Ive had with the 5r seem to be very common. There's lots of evidence of people having the same results. Both on the web and of you ask around locally.
Barrels are occasionally bent by gunsmiths and barrel makers to put them straight. Good barrel makers stress relieve afterward though. On a hunting rifle it doesn't matter as you shot will be cold-bore, but a non stress relieved barrel will likely not allow string shooting without seeing a shift in POI
I think when they send it to the barrel bender it means they put it to scrap...
One other point. Yes it does hold this accuracy out to 200 and 300 yards. I haven't tried further yet.
I've also shot a few other 5R rifles and they shot sub .5 moa. Even at 200 yards.
No I'm not a particularly skilled shooter. These were my first attempts at shooting for groups with a rifle other than a .22LR. I shot .22LR during the winter at 20 meteres and then went out in the Summer with the 5R.
Sight in was 3 rounds of 165 Federal Fusion. Perfect tracking and repeatability. Then 168 federal gold. One click difference. By the way the 165 fusion shot 3/4 moa out of this rifle. Not bad for hunting rounds.
I've also shot this rifle 5 rounds, no warm up, no fouling shot and no sighters. The group was .5 moa. Dead on first shot. A bit larger than the others, but still fantastic.

Nice groups, looks like you have a fair amount of trigger time. So, how does the group size stay the same with the 5 R @ 200 ?
Called around to a few dealers, no info at all if still in production , Remington web site don't show a listing, any dealers stock the 5R ?
Thanks for the input guys![]()
