What uppers will fit the DPMS 308 lowers ?
Besides the DPMS units , of course
RRA?
Others ?
JD Machine
Iron Ridge
Kaiser
AR Performance ITS-12
Looks like the SR25 platform is slowly becoming the standard.
Thanks Josh , I kept searching different sites but couldn't really get an answer .
I wanted some options to build a platform on my CMMG lower.

I think the JD Machine looks the nicest. Plus if you got the G3 style lower it's already got the relief cuts for the mags.
I was on JP Enterprises site , and really like the bulk of their LRP-07 upper receivers , and the fact that its set-up as a side charging unit.
I sent an email to them to see if their uppers are even close to the DPMS footprint . They take DPMS mags . . . . sooooo . . . .
Fingers crossed.

LMT MWS upper fit and function checked on my DPMS lower but there is a gap at the rear on each side. DPMS upper will not fit on the MWS lower without removing a significant amount of material from the DPMS upper.

Last I checked they don't sell the upper separately. Secondly, it's SR25 pattern. It will fit, but there will be a gap.

The gap I might could deal with ............as far as not being available solo

It's been probably about a year since I asked them about it. Maybe they've changed their minds since then.
Are you sure the JP is completely SR-25 patterned, I thought they had the rounded upper like the DPMS/Remington/Bushmaster rifles? The new Remington RSASS is practically the JP LRP and it is most definitely .
There's also Fulton Armory, SI Defense, and Tactical Machining is suppose to be coming out with a DPMS compatible upper soon. POF will work with some "jerry riggin"
I have one of the IRA uppers, the are nice but pricey. The DPMS uppers are by far the cheapest, SI has some that look very similar to the JP uppers if they turn out to be unavailable.

Not 100%.
Fulton Armory is DPMS.

I cant find a decent shot of the back of their ( JP ) uppers
Those SI Defense Gen 1 308 receivers are pretty nice, though I'm looking to build the weapon as a side charger.

Don't tell Fulton Armory that! I didn't even say it but somewhat eluded at it and the idea wasn't happily accepted.
A member just sold a JP-LRP07 . . . look at the third and sixth pictures, definitely looks rounded.
JP LRP-07 SPF
Kaisers are available as a side charger if thats what your looking for.

So it does, I stand corrected.
