You cannot put an Armalite AR10 upper on an Aero Precision M5 lower or Palmetto State's PA10 or Rock River's LAR 8. They will not fit at all. There are some manufacturers that have been proven to interchange but that is, sadly, few and far between. As a point of fact, AR10 is an Armalite designation for their 308AR rifle. https://www.80percentarms.com/product_images/uploaded_images/33-pnqy4j3ys-qv-6l6rlnvsq6zu8txhp5sv6lhi60e.jpg As long as they are dpms to dpms or armalite to armalite they are compatible.

For example swap the 308 with a 6.5 then 243 at the range, similar to how you can swap uppers on an AR15 with different calibers without any issue Yes, dpms to dpms or armalite to armalite. Most out there are dpms, look for the flat or radius at the rear of the upper receiver Quote Link to comment Share on other sites More sharing options...

We always recommend sticking with the same manufacturer for the upper and lower, WAY fewer hassles. Quote Link to comment Share on other sites More sharing options...

Here again JT you are absolutely right,, for example, Wilson Combat is a DPMS pattern rifle with the "ArmaLite" cut ,, so no, if you are not running the same brand of upper and lower, do NOT assume that an upper and lower are compatible, they most likely are not, so run the same brand upper and lower if you are not sure.. I've seen some cobbled together rifles that clearly are not compatible and yet people wonder why they do not run.. its been a while, so don't hold me to it, but Stag 10 is another receiver that is a DPMS rifle with the "ArmaLite" cut on the rear receiver halves,, and if I'm not mistaken?? they have proprietary pivot pins?? I've given up on building an ArmaLite rifle due to my own ignorance and parts availability.. Quote Link to comment Share on other sites More sharing options...

If it's dpms then why have an "armalite cut" as you put it? Also, I've heard and seen strange things over the web and from friends about uppers and lowers fitting correctly. When going same to same, if there are any issues it's most likely a tolerance issue than incompatibly 🤔 Quote Link to comment Share on other sites More sharing options...
shooterrex Posted October 28, 2021 Report Share Posted October 28, 2021 Armalite uses a different thread pitch on the barrel nut along w/the slant receiver cut. Some use the DPMS thread for the barrel nut but have the slant receiver cut. I believe Diamond Back is that way. Palmetto does their own thing but uses the DPMS threading on the upper.

They changed the TPI as of the first of 2021 from 16 to 18 on the barrel nut. Their rails give you one barrel nut of each TPI. Quote Link to comment Share on other sites More sharing options...

Some use the DPMS thread for the barrel nut but have the slant receiver cut. I believe Diamond Back is that way. Palmetto does their own thing but uses the DPMS threading on the upper. The early Live Free Armory receivers had the slant cut, and ran both thread pitches - some were 18 pitch and some were 16 pitch - so you even had to be careful with those, for handguard/barrel nut choice. Now, all the LFAs are no slant-DPMS LR-308 based. I have an early LFA set, and testify to that, and provide pics. 4 hours ago, ValleyCook said: I'm not trying to split hairs here, but here we go... If it's dpms then why have an "armalite cut" as you put it? That is exactly "splitting hairs" and I'll give you the direct answer: There IS NOT a mil-spec on large-frame ARs. Nothing to "follow", for any manufacturer, so any manufacturer out there can do whatever they want, whenever they want. As consumers, we have a giant ball of trash to wade through, every single time a new manufacturer releases a new rifle. Gotta figure out WTF they did with this thing.

ValleyCook Posted October 28, 2021 Report Share Posted October 28, 2021 So now y'all talking about the nuances of barrel nuts, tpi, etc. The question was can he slap different uppers on his single lower at the range?

This is a crude way to sort out which will feed through the mag well but no means perfect. The 7mm-08( Remington and Ackley) are both 2.035" vs .308 at 2.015" If I remove the case length constraint then there are 1112 caliber options. A number of those would regulate the large AR frame to a single shot Quote Link to comment Share on other sites More sharing options...

The .260 also didn't show up( for me) till third list because of case length at 2.035". If I change the parameter to cases up to 2.035" then there are 544 caliber options Quote Link to comment Share on other sites More sharing options...
