Ar10A Lower, up a creek without a paddle


Mirza11

Recommended Posts

This is my first post on here so i apologize if it's in the wrong section.

 

A little background: I am building an AR10 308 rifle and i have searched far and wide (google, local gun shops, Noveske customer assistance) and can't seem to get a straight answer. This is my 1st rifle build and frankly i should not have started with an AR10. Whenever i call either Armalite or another manufacturer i get the "well we recommend using our parts", which wouldn't be a problem if Armalite ever bothered to re-stock their online store. I also know this topic has been beaten to the ground over and over again so i apologize if i am asking the same questions that have been answered 100 times. WIth that being said..

 

What i have:

Chainsaw Noveske Stripped N6 Upper Receiver *Armalite Compatible*

AR10A lower (Accepts non proprietary mags) 

 

MY questions are: 

1.) Are these receivers compatible (I know there's a DPMS and Armalite patterns). Now the upper DOES "fit" the lower (angled back, takedown pin as well as the pivot pin look like they would fit and line up) but its gets muddy because i have heard there is also a high and low profile for both the DPMS and Armalite patterns.

 

2.) IF they are not compatible (Novske rep. said that this was for the B style rifle) what can i do to make it compatible? ( i was told a small piece of the upper would need to be machined off to work with the A style lower).

 

3.) What manufacturers are known to work with the AR10A lower? (I want something close as possible to an Armalite upper fit) 

 

4.) I was told by the Novske rep. that the AR10A lower WILL accept a DPMS upper. IF this is true, what is the profile? (high or low) Is there any manufacturers that do the DPMS pattern which will fit flush on my lower?

 

5.) I bought a 16" barrel from Armalite for the AR10, will there be any issues with fitment with the AR10A lower using the noveske upper? Any issues with the handguard? WIll it accept a free-floating handguard? Any issues with the top profile lining up? 

 

6.) When it says "will accept 3rd party mags", does that mean ANY manufacturer's magazines built for the AR10? If not, which ones will work for the AR10A? 

 

 

 

 

Sorry about the length. Please feel free to share any relevant information on this topic, my knowledge is limited so any help is greatly appreciated.  

Stay Safe

I can't help with all of that, but here are a few

The high/low is strictly a DPMS thing. It describes how tall the top rail Is over bore axis. It's important when choosing a handguard to ensure that they are the same height or you will have an ugly "step". It doesn't affect functionality. All AR10s use a standard height that is about the same as DPMS high. DPMS low is the same height as standard AR15 receivers. I'd assume your noveske upper is AR10 height so you don't need to bother with that...But you can measure the thickness of the shelf over the charging handle to be sure.

 

The A lowers are designed to take PMAGS, or any of the other DPMS pattern 308 mags. (3rd party) not the proprietary AR10 mags.

 

A DPMS upper will not fit your AR10 lower. At all. you should not take any more advice from the rep who told you that.

 

Your AR10 barrel should work fine in the Noveske upper, but if it's designed to work with the B lower, it may not function properly on the A lower. I'm sure one of our armalite nerds will be along to help with that question.

Now, that being said.

I'm not even sure if that lower will fit that upper. The Armalite "A" pattern is a new animal to me. I know that Noveske used to build their equipment off of the Armalite "B" pattern, but I'm not sure if the "A" pattern will match up.

2.) IF they are not compatible (Novske rep. said that this was for the B style rifle) what can i do to make it compatible? ( i was told a small piece of the upper would need to be machined off to work with the A style lower).

You're done right there. They said that it was compatible with the "B" pattern. That's for us older Armalite guys. Us dinosaurs of the "B" pattern are a slow breed to die. But Noveskse, from what I gather, is still staying true to the original "10B" pattern. That won't fit you're lower.

 3.) What manufacturers are known to work with the AR10A lower? (I want something close as possible to an Armalite upper fit) 

I'd stick with an Armalite "newer" upper in this case. Just make sure, through Armalite, that it works with your "10A" lower. Probably best to call them.

That being said. Noveske makes REALLY nice stuff. I use their barrels in a lot of my builds. Including their SBR N6 Leonidas barrel.

IT KICKS ASS!

Its refreshing to have a forum that allows you to let you express yourself like were talking with old friends.

I like to compare this place to a dive bar, we may look at you funny when you first walk in the door, but after awhile we'll be yelling your name when you walk in the door. 

 

And a lot of us have become old friends 

 

Robo puts it well too

Gents , I can get salty as good as the next guy. On another firearm forum, I wont name. I was banned for not agreeing with a admin and gave him my opinion , in a respectful manner I thought. Regardless, I told him in private to go F himself in a PM and to ban me for life. They were a bit "PC" on that site. Guess he didnt like being called out in public?

Hey, I thought that I had told Blue to go Fuk himself in a very respectful manner. :laffs:

A lot of us guys have become more than just names in the forum. We've had various meet-ups that give you the chance to put a face to the name. A lot have exchanged phone numbers and talk with each other frequently. And no matter what the level of ball busting that is seen around here, there is always a level of respect that all of the regulars have for each other. Hell, it even looks like it gets heated up between guys at times. But it's almost always (in the end) just two guys approaching a subject with different opinions or viewpoints, and holding a civil conversation about it (whatever topic that "IT" is).

Blue is one of the guys around here that I haven't met face to face yet. But I look forward to hooking up one day and bullshitting over a beer. And THEN.........I'll be able to tell him to go Fuk himself in person. :lmao:

Truth, we "B" Armalite guys are few in number, but we have each others back. Unless of course, someone gives me a free matched Mega Upper and Lower, then I may have to rethink things.............:banana::fullauto:

To get back to the original question - that upper and that lower will not work together.  When Armalite made the A rifles to accepts PMags (and other DPMS/SR-25 compatible mags), they made changes to the upper receiver to accommodate those mags.  Not only are the A and B lowers different - the A and B uppers are different.

Here's the no-shiit real information on this stuff:

Keep laughing there tough guy. Florida is only about 12 hours from me. :bat:

Sheeet, IIRC Arizona was only about 12 hours away from you! :laffs:

Look out SS!!  R2 is trying to set you up for a 12 hour wait when he's only 3 hours away by F-150 warp drive!
