View Full Version : Building my 2nd OLL....

I'm slowly building my 2nd OLL and I want to do a carbine build. I have some mock-up to show and would like to get some help on deciding which way to go.

For the parts here's what I have in mind:

CMMG 16" Med-Con upper
Double Star OLL lower (on the way)
Troy 13.5 MRF handguard
CA (Centurion Arms) sights
Tango Down grip

Here's a photoshop mock-up of the rifle: (dimensions are not correct)

Version 1 (pretend the stock is black :D)

Version 2

Version 3
http://simple-photos.smugmug.com/photos/175152781-L.jpg

Which one is better? What version would you go for?

The bbl looks long in this mock-up, but I used a Stag Model 3 rifle to chop up.

Top one looks better, but put the Vortex on it instead of the fake can.

And for heaven's sake, tan buttstock with the rest of the furniture black? :)

If you're going to spend that kind of money though, I'd consider the fancy CAA stock with the rear monopod. Sure, it's $400, but it's uber purdy.

I would have to say #3, It looks better then #1

The buttstock on version 1 will be black (just couldn't find one with a good angle)

Version 1 has a Noveske KX3 FH :)

The KFH on a barrel longer than about 12" serves almost no purpose.
It makes the gun far too muzzle heavy as well.
If you want to go 13.7" and permanent attach the KX3, a bunch of that ugly barrel goes away between the handguard and KX3.

Otherwise, go with a phantom or vortex.

I like the A2 stocked one the best.
It looks almost like a proper rifle.

The Noveske KX3 increases backpressure and aids in the reliable cycling of SBRs. It also directs the significant muzzle blast (and some of the sound) of an SBR away from the shooter. It may be classified as a flash suppressor, but I don't think it would do very much besides add 3" to the length of your rifle.

Thanks guys, that's 3 votes for #3.

I'd go with #3 also, unless the full stock does not fit you well.

I don't have any problem with a full stock and I'm also considering just having an A2 stock instead of a collapsible one.

I think #3 is the better looking one. I am also getting ready for my second OLL build and was thinking of a Collapsible sock, but the A2 stock does look nice though.

I'd go with #3 as well, but I really like A2 stocks. YMMV

I like the A2 stocked example.

Best place to buy A2 stocks?

Do the CTD ones come with everything necessary?

Troy handguards are good to go.
I stock the 7.0's because they are the most popular.
I have installed different lengths as well.

Here was a fun one...

The inside of the rail had to be machined to make it fit on a POF piston upper.
We researched several different rail systems for this and the Troy ended up being the most viable option.

And another fun one...

And I was going to pick up a VLTOR upper. Is this the only way to make it work for the VLTOR MUR upper?

But I guess if I'm going to go with a VLTOR upper with a Troy HG, I might as well get the VIS upper and be done with it. It might cost a couple hundred buckaroos over my budget though.

Some people have filed and dremeled Troy rails to get them on a MUR.
While it works, it's not as nicely looking.
In MY shop, milling is the best option so that's what I do.

The VIS is certainly a good option.
It's $50 to do all the fitting of a Troy to a MUR.
I can supply you with a finish matched pair as I sell both Troy and Vltor.

OK.. you say you want to build a carbine.. all the above pics, at least to me, show regular length barrels... To me. a carbine is a short barrel.. such as my last build.. 11.5" barrel with a 5.5"FS and a collapsable stock...

I think most people equate a "carbine" as something with a 16" barrel.
Rifles have 20"+ barrels.

I'm curious why you chose an 11.5" barrel when your OAL still has to be 16" long.
Perhaps something like this would have been a better way to go:

http://ar15barrels.com/tech/fake115.jpg

This is a 14.5" barrel with the LOOKS of an 11.5" barrel.
As we know, the 11.5" flash suppressors do a crappy job of flash suppression so the length of the barrel inside the FS does not really matter.
Might just as well have more velocity if you can...

I did the 11.5 barrel with the 5.5FS only because I already built a 18" middy and a 16" CAR

NRAHPS,
What AR15barrels said. When I did the photoshop mock-up, I used a 16" Stag upper for that and just layered on the Troy 13.5" handguard.

AR15barrels,

I might send my barrel to you if my budget would allow it. I'd like to have my 24" threaded so I could add a muzzle brake.

I have threaded 24 barrels total friday and saturday of this week.

My shop services page (http://ar15barrels.com/services.shtml) has pricing and descriptions of the services I offer.
If you need something that's not listed there, just ask.

just get the regular vltor carbine modstock with the side saddles.
