New AR Dilemma

[Seraphim]

Well Im bored and I got a bit of money to burn. Barrel length will be 10.5


1. Vltor VIS

Pro - Removable lower hanguard
Standard barrels
Modular design
Dont know how much good that will do me.

Con - Not KISS

2. LMT MRP

Pro - "Quick" change barrel/small circumfirence rail.
Rail circumference is small.
Machined from single piece.
6.8 barrel and bcg.

Con - Possibilities of barrel coming loose - less barrel options.

3. Larue Monolithic Upper

Still in the making.

So far, removable lower hanguard, 7075 alloy machined from single billet, standard barrels.
And its from Mark so you know the **** is going to be tight.

Con - Oh the wait!


If Im missing something and Im pretty damn sure I am...please fill me in!

Thanks!

Ever heard of Daniel Defense? They make pretty good rail systems. Have you thought about Knights Armament? (RAS, RAS II) Well, LMT is pretty solid. Check out the Noveske KX-3 flashider on the Noveske website, look at the photo gallery-you might get some ideas. . . Make your 10.5 build a free-float!

[Hispeed1]

Then use a Troy front & rear flip sight, a VLTOR stock, Tango down forehand grip & rail covers, TDI/First Samco G27 handgrip, EOTech 512, Surefire M951. . . Ooops, sorry-that's stuff I'm putting on my build. Heh-heh.

[Durandal]

Do you really want to go 6.8?

Keep in mind that the benefits of a free-float on a short barrel are minimal at best.

10.5 is pretty much a dedicated close quarters type weapon so free float wont matter much.

The VIS is pretty simple compare to a MRP, it still utilize any mil-spec AR barrel. I thnk VIS will take a lot of business from the MRP. there is basically nothng that a MRP can do that a VIS can't...except for the quick change barrel.

I had my MRP for a few years of very hard use. I have not had the barrel come loose. Few users did not torque the barrel nut to spec so it became loose. 10.5, 14.5, 16.1, 16.1SS and 18SS. 5 options that covers a lot of base. with two rail length to choose from..


3. Larue Monolithic Upper

Still in the making.

Agree.


Call Wes at MSTN, he has a Shotshow package that he purchased from LMT. come with LMT MRP with 5.56 and a 6.8 kit plus some other goodies. It has a pretty good price to it. I think if you got cash, this is the package to burn it on.. :)

Not in a 10.5
I wouldnt mind tinkering with some handloads since no one around here carries 6.8spc.

Thanks for the input on the systems. I'll check out the package.

I hear alot of reliability issues with the 10.5. What is the best one that is the most reliable out of the box? Argyll commented on how his Bushmaster performed rather well (with proper maintenence of course) in Iraq.

CQB-R are problematic at best when hammered to beyond its normal operational tempo. Most of the time, when some one decide to dump mag after mag using the CQB-R with suppressor, it will cause failure on a pretty regualr bases. This is why most if not all JSOC has gone over to the more reliable HK 416 in the CQB-R format.

Under normal combat situations, with the Crane o-ring installed, the CQB-R has proven to be reliable and also effective against soft tissue using the 77gr MK262.

[Seraphim]

Are they still using the Crane o-ring or have they gone to the D-fender?

But, as a civilian shooter, this won't be a big problem?

As far as I know. All M4 CQB-R are equipped with those O-rings.

As long as you can apply for a SBR in your state, the gun will run flewless as long as you take the proventive measure such as keep it semi clean and use O-ring and make sure they are fresh every few thousand rounds. having a PRI fatboy doesn't hurt neither.
