I’ve read some musings that it is fragile. Is it viable for seriously hard combat use?
I was wondering the same thing.
I want a super strong rail.
Centurion is what I think Im going with
There was some ancedote stuff about barrel nuts coming loose.
If you want something “combat” tough, the DD RIS-II has a NSN attatched to it as is extremely solid. Not that the Army buys only the best things in every circumstance, but it is my understanding the RIS-II went through a testing process and came out on top. There was an article on Gear Scout about it.
Noveske’s SWS rail appears to be pretty darn solid as well. I think the rail is pinned to the MUR uppers which sounds pretty damn solid.
The SWS rails are heavy though.
I’d go with KAC URX III, DD, or Centurion over anything else on the market right now.
Has anyone used the ARMS S.I.R?
That thing is almost 4 bills.
I would imagine its pretty tough
I didn’t think anyone put ARMS and tough in the same sentence unless they were joking.
Cost is not synonymous with quality.
I have to agree, mine definitely exceeded my expectations.
At least compared to other rails I’ve used.
Its used on the SR25 (same setup just a little bigger) M110, Mk11, and is used by the Secret Service at the White House and protection details.
The only thing Ive seen is the front sight snapping off on some M110’s but soldiers can destroy anything.
I did have one come loose but I don’t think it was installed properly with thread locker on the barrel nut. Both of my KAC factory guns have not had any rail issues. 18k rds through my SR15 and 3300 through my EMC. If it were ever a possibility I would not hesitate to use one in a deployment.
That said I think the DD RIS II is a more solid rail and allows for more user preference. The RIS II has anti rotation tabs (the Lite rails do not unless they recently added them) which the URX does not.
Absolute garbage.
Agreed. One of the first rails I bought before I knew better. Around 2006 or so.
The SIR is junk, and I speak from experience. I have an SR15 upper, my only reservation is the flip front sight. My preference is for LaRue rails though.
Sorry for the thread drift, but I was wondering if there have been any cases of the DD lite rails rotating? With a rail system as seemingly solid as the lite series do you think that anti-rotation tabs are necessary?
I have broken two front sights, one needing replaced. Not a big deal, but it happeneded. Then, I had a barrel nut come loose. I could squeeze the side rails towards each other and they’d show flex.
What does any of this mean? I have no clue, just giving my experience. Luckily I sold them, one to a sucker by the name of David, a member here! (I PM’d you back twice!)
I had a LW URX II and never mounted it then played around with my buddy’s URX III rifle length and it doesn’t seem as sturdy as the URX II, but it’s also longer with less support on the side rails due to the thinner profile. Again, not a big deal, it just doesn’t have the same feel as some other, more robust designs. At the same time, I really like the profile of both, the URX III having a slight edge.
Most likely that flex is a good thing as a hard impact will be partially absorbed by the flex instead of it all being sent straight to the barrel nut.
But, I should stress that a little bit of flex and broken front sights mean nothing when it comes to the top rail holding zero for your laser and the mount itself not coming completely loose. It would have been nice though if the URX II was rotation limited.
I have two Daniel Defense RIS II’s and they seem bombproof. What I prefer about them is even though they’re also a two piece design, the front of the rail has a solid piece that supports the side rails.
Please understand I’m not bashing the URX rails in any way, I’m just stating my experience with them. Nothing is perfect and there’s a trade off for everything. A URX III without an integrated front sight would be high on my list for my 18" precision rig whenever I get around to it. I believe the one for one of the blackout’s has a complete rail without the front sight. That would be great in rifle length.
Sorry if I flip flopped there. I put one of them through a lot of abuse and it kept going strong where lesser rails would likely have bent or broke.
I don’t recall ever hearing of a Lite rail rotating but DD either had reason to or did it just as an extra selling point. Either way it doesn’t hurt to have them as an extra layer of weapon ruggedness.
On another site a poster bent the bottom rail of a RIS II after shooting with a bi pod and leaning into it. The bottom rail towards the front bent downwards slightly (maybe 3/16ths). DD replaced it of course but Im not sure if they had any design changes. Im not sure if he had the screws in properly because that part of the rail is supported by the screws right at the front.
Maybe thats one situation in which a one piece rail might have some merit. I generally dislike 1 piece rails because I like to take an oily rag to the barrel for rust prevention.
Eh… spray paint doesn’t rust.
I don’t care who you are…that shit’s funny! A sucker born every minute!
So far, I like the URX II. I haven’t used it “hard” yet but I don’t think there would be any issues. Now, if you don’t know a thing about weapons and how they work (Jon) then I guess you could break things…
The SR15 that I just got is pretty frickin awesome. Again, I haven’t run it hard but I can’t see where it could fail. As long as I’m not using my rifle as a hammer…
Plus, as a civilian, I’m hoping I never have to be in combat.
I have never actually seen one in person.
I thought they were the “Elite” rail lol hahaha
Belmont, sorry you got fooled into it. That sucks losing that much money on a garbage product. I would be pretty pissed too.
I know NOTHING about that rail other than I hate the “piggyback” the upper design and its expensive as hell.
Sorry for the hijack there
I sold it for almost as much as I paid…
