I am requesting velocity numbers for short barreled AR-15 rifles. 7.5, 10.5, 11.5 and 12.5" barrels are of the most interest to me. Please include barrel details and ammunition used. If you have the conditions of the location and day that's even better. Thank you.

Too bad us plain users cannot use the "search" function effectively, so I have to type this in for maybe the 4th or 5th time. Using my chaep green chrony and 3131A: 7.5"- 2382 11.5"- 2788 20"- 3234 The 10" and 12" barrels will closely mirror the 11.5", 12 being slight faster, and 10" slight slower, not by much for 1" of barrel either direction. I would not jump up or down over the small details, though 10" is sometimes ammo picky, due to slight shorter "dwell" time past gas port.

Well, as for not being able to use the search function... I tried. You can't search for something that's only 3 characters ("SBR"). "SBR Velocity" didn't return anything either. If you have some other posts that have even more velocity numbers, please feel free to share. Thank you very very much for posting your velocity numbers. I really appreciate it. Thank you.
