[QUOTE="Darryle, post: 2698859, member: 109917"] It's 2" longer than the rifle length, lowers the pulse of the rifle and increases the dwell/lock time of the bolt, the further the gas port is out, the easier it is on the rifle. It has to have a properly drilled gas port as well, simply moving the port out without changing the port diameter will create more problems than it alleviates. The same thing can be accomplished with any gas system length by tuning the buffer spring and weight, nothing I own or assemble comes with anything lighter than 5.3oz. I have a couple of carbine 308 rifles that have buffers as heavy as 8.5oz. Dumps brass in a neat little pile about 6' @ the 3 o'clock position with no adjustable gas block. Here's are a couple of short explanations of gas system length choices [URL='https://www.at3tactical.com/blogs/news/9298047-carbine-mid-or-rifle-a-beginner-s-guide-to-ar15-gas-systems']Gas system lengths[/URL] [URL='https://www.shootingillustrated.com/content/ar-gas-system-lengths-explained/']Gas System Lengths Explained[/URL] [/QUOTE]
