Starting new build...need a suggestion

[rxer311]

Maybe I will rethink the rail then...

[UWone77]

I agree. The NSR barrel but is crap and the main reason I have 1 or 2 installed. The rest got replaced for other rails like Geissele as Slippers mentioned.

I know SMOS was looking at redesigning the barrel nut when they were making NSRs

2 oz. Or 2.2 to be ultra specific. Not that it's better, just lighter, and at around the cost of the Alpha you could get something like an SLR Helix which is nearly identical weight to the original KMR. Some of the MI rails weigh the same as the KMR Alpha but with a shaved (not sure proper term) top rail so you have a smaller circumference. The Helix does as well, as well a couple other of the SLR series.

It's just about weight for me. I think the forend is THE best place to shave weight (due to forward location) without any fear of performance penalties (like some lightweight barrels have when they get hot, such as POI shift).

Seems like the Helix is closer in price-point to the original KMR than the Alpha. You can get the 13" KMR-A for around $160 if you look around and I suspect it would be hard to find the Helix 13.7 for much less than $220.

For all the talk of the M-LOK being cheaper to manufacturer, it's interesting to see that the M-LOK Helix cost $5 more than the KeyMod.

That's an apples/oranges comparison. Helix doesn't merely machine mlok slots.

I would also be interested in trying this new rail system as well. I wonder how strong it actually is?

[Aragorn]

Guess you could always split the difference and get a KMR Alpha and install it with a V7 Ti barrel nut, then you'd have the stronger forend and only be an oz more than the lighter one.

I agree the barrel nut sucks with the NSR, but it's also something that you're probably only going to have to mess with once. I wouldn't walk away from the NSR rail just because of it. Compared to installing a KAC URX 4 over a pinned gas block, the Noveske is a walk in the park.

Comparing the 13.7" Helix M-LOK ( http://slrrifleworks.com/index.php?r...1#!prettyPhoto )to the 13.7" Helix KeyMod ( http://slrrifleworks.com/index.php?r...product_id=720 ) is apples/oranges?

Its a moot point at the moment...as both are not in stock...

[Aragorn]

Both are in stock at Rainier in all lengths.

Sorry. I misunderstood. Thought you were comparing KMR to Helix. Price difference must be supply/demand difference.

Okay so update...

Since I finished my lower off I started getting parts for my upper. Just picked up a Noveske MUR upper and 13.5" NSR rail. Now I just need to find the right barrel for this build.

[velocity2006]

Look for a 14.5" Afghan if you can find one, that is what I would try to find if I were building that upper and rail combo.

This is what I am thinking as well.

What's the problem with the NSR barrel nut?
