Looking at this low cost UTG RMR high mount it has a hollow channel cut through so you can peep through it to the muzzle

Why doesn't someone make an integrated Ghost Ring rear sight from the RMR mount? Then one can have a short Stubby front fixed sight that is below the RMR and inline with the integrated Ghost ring???

Super light and always available. No springs to fail and less to break off. No need for RMR QD mount either

Does someone already make this system of integrating a rear ghost ring and a low profile fixed front sight system?

Whatcha doing in Vegas?

You want to shoot at Clark County range on Friday? Being retired I can shoot anytime.

I have a lot of rifles you can shoot, try my 4.46 pound AR308, or either of my 22 Noslers, or my 7.62x39 AR, or my 3.2 pound 6.8 SPC.

So everyone knows that Brigand Arms makes the lightest hand guards, but I'm looking at taking a generic 12" CF rail I bought from Delta Team Tactical a while ago (yes that DTT, and yes I already have it in hand) and cut it down to about 7" and remove some of the rails to make a custom light weight rail.  

This is the rail I'm talking about: Generic 12" CF rail

Currently the hand-guard with the mounting system minus the front ring is 6.6 oz.  Plan to take off the rail sections at 3, 6, and 9 o'clock  and trim the top rail to fit, and pair it with at V7 Ti GI style barrel nut.

I anticipate that I'll want something to stabilize the inner diameter of the front ring, much like the now defunct AP custom CF handguards. I'll need to measure the ID and find some kind of pipe or other material to insert without being very thick.

Thoughts?

Since you've already got the cut down CF rail, that mod should work OK. If buying new, the guntec usa 7" with Alum. barrel nut and mounting screws is 6.5 oz.

LMAO, I am sure there is a reason no one want's to be the guinea pig, I haven't quite gone so far down the LW rabbit hole that PB receiver parts are something I'm willing to test. Besides it doesn't have a listed weight! :P  I'll go with V7, I've used some of their parts on my first LW build and they have a solid rep.

Meh :P It's not like it's expensive, lol. The only reason aluminum GI barrel nuts aren't common is the teeth can break off if you use too much torque or a lousy wrench. If it's 7075 aluminum then great, if it's 6061 then it'll still be fine.

I got a couple flash hiders to tame my 5.56 pistol 11.5 build

weights are:

AAC (no suppressor mount) BlackOut 3 Prong = 86.25g ( I believe you already have this in the PWD)
but this one I don't believe you have
JP Enterprises Flash Hider 3 Prong JPFH-556L = 99.5g

wishing for someone to come out with a Titanium 3 or 4 prong version.... ;)

Nice! I'll add the data tonight. I agree that there's some work to be done on the LW FH front. Not only are most of them heavy steel, they just aren't designed with weight savings as a main consideration. I've seen brakes that are, but not many flash hiders. The flaxon slim one does, but more because of diameter restrictions than anything else.

Edited to add:  Scalarworks appears to be in the process of redesigning their mounts, and the weights have gone up a little.  I will post a weight of their new RMR mount when mine comes in (although I would have rather gotten the old version).

quick PWD update: after a few weeks 'off' to travel with my wife, I'm back in the saddle. As far as I know, all data posted in the thread while I was away has been added. Thanks, as always!

Also, for a long time I've been saying that I'll prolly get a Shield RMS for my UL SBR. The more I think about it, the longer it takes for good #s to get in the country, and the more reviews I see, the more I am thinking of going in another direction. I do not like the reviews that mention battery doors being jammed shut. Not good! Since they use the same mounting pattern, I'm thinking of using the Shield poly mount with a DeltaPoint Pro. The DPP is one of the lightest metal micro red dots around...and the poly riser is hella light as well. The Shield is $400+...and the DPP, every once in a while, can be had for $330 (recent PSA sales price). I think that'd be the better option. Still wanna try the double-height Shield poly riser and Ti screws set up though...

b. holy dog poo, I hope their products are better than their www site. Kudos for them posting all the data I need, negative cool points for making the sight almost unviewable due to scaling / lack of scroll option on their site. I had to select all / copy / paste every page into a wordpad doc and then track down the info in there. meh!

All of that said, ALL of their 556 muzzle devices have been added to the PWD.

I use a bobro rear and a rosch slm-1 front. They're the lightest that aren't plastic or leitner wise. The plastic that i refer to are the MFT sights. I have 2 SLM-1's from back when v7 sold them under their name.

That should actually be about .4 oz lighter than the Faxon 14.5 pencil. That price though ouch! I’m not looking for that kind of quality/accuracy with a LW gun. Damn I need to find someone with a lathe!

Breastroker have you seen the v7 high profile 308 magnesium handguard? Right now all they have is 15" but when they make a 10-11" it'll be the lightest metal handguard you can get. And that's with a titanium barrel nut.
Link Posted: 10/19/2017 12:43:36 PM EDT
[#42]
Yeh it is sweet, 308 is larger diameter so magnesium is the best way to lighten it.

But still HEAVY compared to my carbon fiber plus aluminum barrel nut @ under 3 ounces

I have a couple of the ultra light carbon fiber tubes, even have the 308 tube on my under 3 pound AR 15 in 556. I put a CF shim between the larger diameter 308 hand guard and the light weight AR 15 aluminum barrel nut

Yeah, i'm not a big fan of the carbon fiber tubes, i like a more modular design. My lightweight builds aren't bare bones guns, i like having a full suite of features, being able to run a bipod, backup sights, port door, etc. I'm hoping i can get an aluminum barrel nut that'll be compatible with the v7 handguard, blacklabelholsters does limited runs of custom parts sometimes.

Well i'm at 3.35 lbs. I've got a tegra lower, blackthorne polymer upper, Faxon 4150 pencil barrel, 10 in bcm magnesium rail with custom aluminum barrel nut, Shield SMS red dot, smokes stock, arson a-hole micro aluminum brake, and a jp aluminum carrier with adjustable gas key. Getting to 4 lbs can be done on a budget, no problem. Every ounce under that will COST. I'm talking throwing every dollar you have at every part of the gun until your obsession becomes unhealthy and people think your AR is a bb gun :D Of course results may vary!!! The only things i could do to get lighter are get a Faxon stainless barrel, go down to 14.5 inches and permanently attach something, brigand handguard, ETC... I'm gonna stop now, lol i'm happy where i'm at!!!!
