As to which came 1st second third gens of AR-10s, here are some dates to ponder as to latest versions. SR-25 first hit the civilian market in late 1990. It had been adopted by the military in early 1990. Great Magazines, some proprietary components, hit and miss on overall quality. Armalite AR-10B hits market in 1996 right into the teeth of the "Assault weapons ban. Used retro fit M-14 magazines, would accept Reed's SR-25 mags if you could get them. Bolt lug degree of separation, cam pin, barrel nut, and extractor different from SR-25. 2010 DPMS LR-308 Hits market. Bolt lug, cam pin, barrel nut and extractor similar enough to SR-25. Bigger use of AR-15 parts like extensions, trigger groups and pins etc. Magazines hit and miss latter ones held only 19. Heavy as hell, but generally very accurate. 2013 DPMS gen 2 LR 308. Much lighter depending on configuration, more commonality of parts with AR-15. The SR-25 isn't the latest best gen AR-10 platform, but it certainly was the most reliable for a long time due to it's magazine. Rejection rate by the military was at times as high as 30% due to accuracy issues.I have owned and shot all the above, and just about at the time they hit the market. I still own two DPMS LR 308s. One 16" carbine and a 20" pencil barrel with an A1 stock. I have been lucky as all the DPMS steel magazines I have hold 20 and have been very close to flawless. I never had trouble with either of them in the buffer, tube,  spring department using the DPMS buffers and regular springs, but I do know of folks that had problems with them. My current favorite big AR is a Nemo, but it now needs a barrel</blockquote>
