New CMMG MK3 Lower - Looking for upper advice

[brickz_va]

Hi.  I'm a long time troll of some of the other well known forums and happened across this thread due to a new project.  I've built a number of typical AR15's and long range rifles over the past few years.  I thought I would dip my toe into the semi-auto long range rifle scene as an eager to learn hobbyist.  I got a great deal on an new MK3 lower and now I'm reaching out to my fellow forum members for advice on stripped uppers.  I've done the obligatory multi-day search of the posts at hand, but I'm still a little fuzzy on out of the box fit/function uppers available for the MK3.  I've read there CMMG, DPMS, and SI-Defense are most prominent.  Are there any manufatures that I should be also taking a look at?

Again thanks for the very informative posts and providing any bread crumbs in my new project's search for avalible parts.

I believe Tactical Machining tm10 upper will fit also, they are a site sponsor, click link on right  <thumbsup>

Hi Brick Glad to have you here!

although some of our members have had problems with their cmmg's and I myself would never have a cmmg after the way the factory treated our members...for resale's sake put a cmmg upper on it so its not a franken gun....but then again ive  have some franken guns on my ar15 platforms...do you care bout resale?    :)  Wash

edgecrusher - thanks for the input

washguy - sorry to hear the problems with CMMG (not sure exactly what they were - sounds like customer service strikes again)... I'm not thinking resale for this build, but I'm not apposed to a franken gun as it's for me to scratch that .308 itch.  I'd like to get a CMMG stripped upper, but I can't seem to find another source than on the CMMG site.  Any other places to find one?

Thanks fellas!

They do appear on Gunbroker from time to time but I have'nt seen any dealers offering them.

If it wasn't a built rifle by CMMG , its a so called Franken gun any way . IMO , you will probable be able to build a better rifle ,because you will have what you want in it as opposed to what they want in it .

One guy I shoot with has a CMMG 308  rifle , I liked it & has had no problems , but they do seem to have more than there share .

The Tactical Machining upper is a good choice . They are down the road so to speak from me & I just got one & it is real nice .I have it on a DPMS complete lower in the photo , but am leaning toward just getting a TM lower for it .

I can take a photo of it on my older CMMG lower , if ya want .

survivalshop,

  Thanks for the feedback and pictures.  I think the options are limited, but like you said I'll get the features I'm looking for other than settling for a stock rifle from CMMG.

Really appreciated the photos!

So after loads of research and trolling the postings around the Internet I gave in and ordered a DPMS A3 stripped upper.  I remembered that this was a project gun and worst case I sell the lower and get a matching DPMS lower.  I really have to thank everyone who responded earlier.  A noobie around the AR308 platform like myself would have been pissed off as soon as I mounted an upper without enough research.  Thanks again.

Right before the scamdemic, we found a SUN DEVIL upper that would fit my kid's CMMG lower.  It's a little snug and hasn't been fitted exactly yet. It doesn't take the forward assist (no problem) or a door for the ejection port (I'd prefer one though)  This summer I got him a 16" Ballistic Advantage barrel for it.  We're waiting to get a reaction rod to put it together.
