Remington Model R-15 VTR™ Modular Repeating Rifles
My dealer ordered one of these when Remington first announced them. It finally showed up yesterday. Went over there tonight to look at it.
First, let me say that I have a 20" heavy 1" dia barrel flattop. It's a good position rifle to shoot from a rest or bipod, but I'd rather have something lighter for coyote hunting. I have been using an XM177E2 clone, as well as an old AR15A1. Neither of these are optics friendly because of the fixed carry handles, but the weight and balance is closer to what I want in a coyote rifle. I like the collapsible buttstock on the XM177E2, but for a pure hunting rifle I prefer the fixed stocks. I'm tired of getting my moustache and beard caught in the stock. So, what I was going to do was put a medium weight 16" on a flattop upper with a free floating forend and put it on my flattop rifle.
So, when Remington announced the R-15, especially the 18" carbine version, and that it was camo dipped, I held off building an upper.
I'm glad I did, because the R-15 carbine is almost exactly what I'm looking for. It's light, being just a bit heavier than the XM177E2. It's 18" barrel is a good compromise between a 16" and a 20". It has a short forend, trimming weight. I liked how it balanced and handled. I said "almost" exactly what I want. I would like a slightly heavier barrel, but this isn't a varmint rifle that will be shot until the barrel is smoking. It has a 1 in 9" twist. I prefer a 1 in 12" for hunting, but, 1 in 9" from experience will work with fragile jacketed varmint bullets. (Interesting that the R-15 is 1 in 9", while the real maker, Bushmaster, uses a 1 in 8" on their version.)
Note that the R-15 barrel from the bobbed sight tower to the muzzle is fluted. This is not readily apparent from the photos on the Remington website. I didn't realize it was fluted until I actually saw the gun.
And for those who absolutely must have an M4 stock, the 18" R-15 carbine will be offered with one:
Speaking of the Bushmaster, my dealer also had their camo Predator model with a 20" free floated heavy barrel. I compared it to the R-15.

The Bushmaster Predator felt like my Bushmaster heavy barrel, though mine is a bit heavier. But they balance similarly. My dealer did not have an R-15 rifle version, but it's almost the same as the Bushmaster, except for the barrel diameter, slight weight difference, and how the free floating forend has its vents slotted. The Bushmaster Predator weighs 1/4 lb less than the R-15 rifle (8 lbs vs 7-3/4). The difference is the barrel diameter under the forend. This told me that the R-15 rifle was not what I was looking for. (The R-15 carbine weighs 6-3/4 lbs.) Interestingly, there is a substantial difference in price. The Bushmaster Predator was priced about $250 more than the R-15.
As I said, I'm looking for a coyote rifle first and foremost. Would the R-15 make a good tactical/defense rifle? Sure, though whether camo is needed outside of coyote hunting is debatable (some don't think it's needed for coyote hunting either - but I think it helps for the well educated coyotes). But if I was wanting a rifle for tactical games, I'd want a somewhat heavier barrel considering how much ammo will be fired in a short time.
Trigger pull. I was drooling so much that I plumb forgot to try the trigger pull. Bushmaster says they have a two-stage competition trigger (3.5 lbs takeup, 1 lb let-off). I suspect this is their DCM trigger. If so, that would help account for why the Bushmaster Predator costs more than the R-15. Remington says they have a "clean-breaking single stage trigger".
The camo finish on both rifles was nicely done. It's actually a little darker than what is shown in the pictures. Both Rem and Bushmaster are using Realtree Max-1 camo.
The "hard case" that comes with the R-15 comes with is a pretty darn tight fit if optics are mounted. Some scopes are not going to fit in the case. I suspect the locking case was there more to help owners legally take their rifles home in some states, when locked.
Anyway, I liked the R-15 enough that I put it on layway. My son Sean is doing his welding certifications right now, and any welder can tell you those cert tests aren't cheap, so my discretionary funds didn't allow me to bring it home yet. Plans are to transfer my EOTech 552 onto it. Ultimately I'd like to put a low powered scope on it with an illuminated reticle, like the Leopold 1.5-5x. I've used higher powered scopes for coyote hunting, and feel they are limited to use in wide open country from a rest. At that point I'll go to a 22-250 or 25-06.
BTW, if you want my opinion between the Bushmaster Predator and the Remington R-15 20" rifle versions, the difference is 1/4 lb weight, 1" difference in twist rate, the trigger, and the cost. I'd use the 20" model as a varmint rifle, not a dedicated coyote rifle. So the heavier barrel on the Bushmaster is a plus. The trigger is a plus too, but one could always be retrofitted to the R-15. I prefer a slower twist rate, and would prefer that Bushmaster did not use a 1 in 8". (I don't know if a different twist could be special ordered.) Also note that the Bushmaster Varminter wih a 24" barrel is now available in camo. (The stainless barrel version is not at this time.)
