Sisco Posted February 24, 2018 Report Share Posted February 24, 2018 My first suggestion is to go through the 308AR website and the 308AR forum. Go through the archives and you will get your questions answered and learn a fair amount about all of them and which direction to take your build. You will know a lot more that way then having one of us try to answer a really involved question in ten sentences or less. Quote Link to comment Share on other sites More sharing options...
Armed Eye Doc Posted February 24, 2018 Report Share Posted February 24, 2018 As sisco mentioned, here is a good place to start with some of the basic differences. https://308ar.com/articles/ Or the main page at https://308ar.com/ An analogy I use occasionally is to relate large frame ARs (LFAR) to cars. Ford, Chevy, Toyota, etc... all make cars that perform the same basic function. They all have a similar list of parts and components but they are not necessarily interchangeable. 308s all use the same ammo just like many cars use gasoline. Some rifles prefer different brands or weights of ammo just like certain cars run better on different octane gas. When you get to different calibers of LFARs, it is like having a diesel, hybrid, alternative fuel or electric car. You have to know what fuel to put in it to make it go.

boo radley Posted February 28, 2018 Author Report Share Posted February 28, 2018 Thanks Fellers The AR15 parts are pretty much interchangeable. I see that the lowers and uppers of the Armalite 308 and DPMS 308 are different where they join at the upper rear. Ive also read where its better to put in an AR10 trigger and not a AR15 trigger even though it will operate and fit. Quote Link to comment Share on other sites More sharing options...

Pattern purchased from Bushmaster, BAR-10 previously. LR 308 Ive also seen R 8 and there is a 6.2 Creedmor.6.5 Creedmoor (and 6 Creedmore now) Im building a (fill in the blank) and I want to buy the correct parts. Three major patterns, DPMS LR-308-based, Armalite AR-10-based, and Rock River LAR-8-based. Minor patterns, as well, that include DPMS GII, PSA PA-10 is different, etc. Advertisers typically don't know the difference, just that it's a "bigger AR." They will misuse the term "AR-10" for everything from BCGs to barrels to you-name-it. Calling it AR-10 means it's for the Armalite pattern. That doesn't mean it's gonna work in your DPMS-based build. Most of the time, it's really a DPMS_based part, and they erroneously called it "AR-10 whatever." Seriously. THAT is the biggest hazard.

lilmidtown Posted March 7, 2018 Report Share Posted March 7, 2018 Biggest thing I can suggest is there's two different .308 AR patterns dpms and armalite make sure when u get parts that they are compatible with whatever u choose it took me awhile to find the right parts for my armalite.

unforgiven Posted March 7, 2018 Report Share Posted March 7, 2018 If you want to save money on a .308 build, you need to do your homework first. Matching upper/lower always helps. Quote Link to comment Share on other sites More sharing options...
