buttonbuck Posted January 19, 2018 Report Share Posted January 19, 2018 I know a couple of you on here are the ever updated 'google' on compatibility of uppers/lowers. I have a DPMS high profile patterned upper I am going to sell and want to know who makes compatible lowers w/o having to make any mods. I know PWS is a direct fit I've been shooting my buddies PWS upper on the lower I have currently runs like a champ.....gotta be others. That said I'm keeping my lower it's set up beautifully for me and I have a new PWS upper on the way. Thanks guys Quote Link to comment Share on other sites More sharing options...
dsdmmat Posted January 19, 2018 Report Share Posted January 19, 2018 Go ballistic firearms, Lewis tool and machine are the two I have used besides DPMS. Quote Link to comment Share on other sites More sharing options...

COBrien Posted January 19, 2018 Report Share Posted January 19, 2018 Any DPMS/Remington/SR25/LR308 compatible lower will do, not just those that have been mentioned here. Bottom line: If the upper edge of the lower at the rear (between the FCG and receiver extension) has a curve or radius, rather than an angle (like an Armalite), it's probably DPMS compatible.

So as far as functionality there is no worry b/t low profile and high profile DPMS patterns? It's purely cosmetic?

Just sell the Upper , is it a complete Upper with Barrel < HG & BCG ? Photos ? The Lower has nothing to do with the Rail height of the Upper/HG , as long as its is DPMS compatible . Now saying that , I have seen some Receivers that don't play well together from different manufacturers . DPMS , Fulton Armory , Tactical Machining ( I know these because I have them or used them ) & I believe Aero will work . Quote Link to comment Share on other sites More sharing options...
buttonbuck Posted January 19, 2018 Author Report Share Posted January 19, 2018 (edited) I'm not buying a lower I'm keeping mine. I have received about half a dozen emails on my armslist ad asking what lowers are compatible with my upper for sale.

Thanks As survivalshop posted, the profile of the upper has nothing to do with the lower it's compatible with. DPMS High, DPMS Low, and DPMS "High Rise" are simply terms used to describe the height of the rail above the bore. This DOES make a difference if a person is wanting to run a railed handguard, railed gas block, or FSB. DPMS Low is AR-15 height. DPMS High is slightly higher. DPMS "High Rise" is ridiculous (I own one...), and really only intended for optics. Edited January 19, 2018 by COBrien Quote Link to comment Share on other sites More sharing options...

I have received about half a dozen emails on my armslist ad asking what lowers are compatible with my upper for sale. Just tell them it's "DPMS LR-308-pattern compatible." If they don't know what it'll fit, why are they looking at it to buy it anyway? Let them use something that doesn't work, if they're not willing to research it themselves. Oh, I forgot - they'll end up here after they buy it, wondering why they can't get it to work... Quote Link to comment Share on other sites More sharing options...
