Beautiful rifle. What handstop is that? I'm trying to slim my smr down a little and that looks perfect.

It's the Larue handstop. Just a simple modification to make it fit the SMR like a glove. Really popular option with both CAG and AFSOC builds. Here's mine on a 24th STS setup:

Still trying to find a BRN4 or MR556 lower, but this is coming along. Unfortunately the G33 mount doesn’t fit the Wilcox riser, so I’m going to give the LaRue a try. Giving it a run with the M4-2k tomorrow as well. As soon as the front riser gets in the KAC micros will go back on.

There's an mr556 lower on Gunbroker.

It's only at 1200$ right now

I need some suggestions on optics for my 14.5 416. I have a 10.4 with an eotech Exps 3-0 so looking for something a little different. Any suggestions?

Having a scoped 14.5 paired with a red dot 10.4 is pretty great. The red dot with magnifier thing is really great for 0-200m and it really shines at close stuff like CQB. But a 14.5, especially suppressed is great at that "recce" or "spr" role. Think around 50-500m stuff, bipod, CNVD, etc…

An obvious option is the plethora of high quality LPVOs that are out there right now. The Vortex 1-6, 1-10, NF 1-8 atacr, NF 1-8 NXS, any of the S&B short dots, etc… They're extremely high quality and they've come a long way.

The only downside is some of them tend to make small sacrifices on the long end to be able to get that true 1x. And if you already have a 10.4 that true 1x might not be as important to you as it is to other people that are building a "do everything" rifle. This was my situation so I personally did a clone of an AFSOC 416 and went with the NF 2.5-10x32. But any of those typical recce/spr optics are a great choice, the 2.5-10x24, the x42, etc…

14.5 is an extremely common length right now in SF as well with the URGI, so find those threads and take a look at what guys downrange are throwing on them - will give you a good idea on the current role those play and what works since they also have access to their 10.3 CQBRs. (similar duo)

Here's my AFSOC clone with the 2.5-10:

So, because I'm not paying 3k for a bolt carrier, would it be dumb to buy a new MR556A1 for parts? I have a line on a new one with the lighter profile barrel for 2900. Other than the barrel, gas block, receivers, and rail, I could use everything else on my second build.

It's a really really great option at this point. 416 complete uppers are getting into the $6-$8k territory right now. And you're still left figuring out a lower situation, which is either $1200+ for an MR556 lower or still costly with a brownells lower and all the right lower parts (and terrible fit).

With the MR556 you're paying 1/3 or less than that and you're getting basically everything you need. At that point, you can easily pick up a Hurricane, Nefarious or Brownells barrel if you want a different length or something more rugged. The only downsides are going to be the marking on your upper receiver, the cut out in the bolt carrier, and the MR marking on the bolt carrier.

Speaking of Hurricane barrels, they have "clone" barrels that are chrome lined, are those decent?

I'd be interested in the barrel/gas block.  I was gonna send my upper off to Marvin and have it profiled and cut to 14.5 but this would be better.

After shooting out two MR556 barrels (one of which was nitrided), i couldn't wait to get my hands on several nefarious arms barrels.

CHF and chrome lined. This is the way.

You found the nefarious arms barrels to be better? The factory barrel in my MR556 is stupid accurate.

How many rounds did you put through your rifle to shoot out not one, but two factory barrels?

Around 10k for the standard barrel (with multiple full copper removals every few thousand rounds due to key holeing. I gave up cleaning it after the 10k mark.

The nitride barrel started the same crap after 5k to 6k rounds and when i gauged it for bore erosion (adjusting the reading for the tapered bore) it swallowed the gauge like a porn star.

Nitriding also destroyed the temper of the bolt carrier "tombstone" and the op-rod. Both deformed during the 5k rounds it took to eat the bore of the barrel.

After replacing the carrier, op-rod, and installing a nefarious arms chf chrome lined barrel, all is well.

It’s a real 40mm. Though I don’t think I’d ever fire it on this rail, the recoil lug for the HK rifles is on the gas block, not the hand guard. The only thing holding the recoil would be the handguard bolt, that’s it. But it’s fun to mount it up…

[Last Edit: IneptKomodo] [#41]
I finally offered up my first born son, one kidney, and the rest of my soul, and managed to secure an otb 416 carrier, only problem is it has had the firing pin safety removed.

I get that the carrier has an increased velocity, at least some people's do, but is it really necessary? My gun is extremely gently cycling compared to how others talk about it. The first thing I tried was dropping the bolt repeatedly on casings with soft primers, and I couldn't get it to slam fire. The indents from dropping the bolt aren't any deeper than any of my DI guns, and I could always just use a standard DI firing pin as it is lighter to help prevent slam firing, providing it's worth worrying about.

I can find what I think are the right parts to replace it minus the spring if it is a big deal. My other question would be how do you install the safety catch? Some places people say you need a special press and all this other stuff meanwhile some people get their carriers nitrided which requires it to be fully stripped, which is done with little fanfare. Any help is appreciated.

@JoEnge1136 it’s riveted in place and very easy to do. Use a pointed punch to tap the end which flares the rivet. I think I have all the parts too if you need them. Hkbeltfed at yahoo dot com
