I know that will add to my weight but I like the site longer radius. will be going with a 16" barrel because I want to keep the ability to change flash suppressors easily and will be adding a silencer if Ohios Silencer Hunting laws go through.

Back to the point this thread and the FDE thread will make me put this rifle together faster than Ill want to. Thanks guys.

This one appears to be a little on the fat side.

Well got most my parts in.  And just a hair over 5lbs but thats with a M16 BCG will be swaping for a LMOS. And that's a 16" barrel I have a 14.5 coming.
But didn't have a flash hider or sights yet.  So with the parts swap I should be right around the 5lb mark would be nice if I go under.

If someone were to build a 10" Barreled Ar with a pistol positioned gas block and a 3.8oz boomfab carrier - where can run learn about the tricks to properly setup and run such a system?

What buffers to be used? A pigtail gas tube?  etc.

Pistol length gas on a 10" 5.56 barrel is a bad idea.  High port pressure coupled with excessive dwell time is just asking for parts to break early.

ETA:  you'd also have a hard time finding that barrel, I've never seen it as an option on a factory barrel.

Also, pigtail gas tubes are a gimmick.  Lengthening the gas tube without moving the gas port further down the barrel solves nothing.

What length gas system on a 10" 223 barrel would you suggest?

EDIT: It is either that or a carbine length. Nothing else would fit. Note I would be running an adjustable gas block as well.

CAV-15 MKII lower w/ standard buffer and spring, SP1 Upper, 9310/FA BCG, DD 16" carbine lightweight barrel, VTAC Sling, tactical electrical tape
6lb 12oz with a primary "optic," sling, and full 30rd mag

I'm thinking about butchering up the CAV-15 a bit for a shorter length of pull and a little grip work, and would like to put a MI-FSB light mount on there since I have a TLR-1S that just sits around since I have changed pistol lights.
Also contemplating going to a middy. I have a 16" lightweight barrel sitting around and all the handguard parts, just need a FSB pinned and I might try it, would still be under 6 unloaded with a sling, maybe even with a light

This one weighs right at 6 lbs. unloaded... less with the optic removed.  It is a PSA Premium light profile 16" middy, with a Bushnell TRS-25 red dot.  We put this together for my Dad.

Speaking of Mag Tactical...

A bit pricey but lightweight out of the box. Cool, but not as fun as doing it yourself.

What does the hive say about the lightest muzzle brake?

Anyone know what a A2 Birdcage weighs? Googled it to death, couldn't find it.

The Mag Tac muzzle devices weighs 1.9oz. A BE Meyers comes in a 2.5.

Couple questions. Could you weight your LWRC compact? They state 7.9 ounces.

Also, did you weigh the Ultra-compact stock and hardware seperately? They don't list the weight for the ultra-compact.

Thanks.

Wow. I think I am going to go with the CAR stock at 4.4oz for now. If it bothers me, I will get a different stock, but one under 6 oz.

I do like that super compact setup, but not at that weight.

Very nice, thanks for the updates. That's what I'm going for too. Lightweight but still comfortable.

If you feel like shaving half ounces off your build, V7 systems has some really cool trick parts available, such as a slick Aluminum Ejection Port Door.

I'm saving up for an LWRC Compact stock in FDE. Wishing they would do free shipping or a sale or something. The Battlelink Minimalist is tempting but for some reason I don't think it would be that comfortable, esp with drills.

All I had left over after cannibalizing my M&P Sport was the upper receiver, the flash hider, the MBUS and the stock. So of course I had to build a rifle out of them. Figured I'd go the lightweight route since the upper receiver has no FA or dust cover:
