Starting a new thread on this because it it different than the original question on wear and tear.
VIDEO OF FIRST TRIP TO RANGE
As you can see this is second time ever using this device, definitely without question does what it says, easy to use, and very controllable (surprisingly so)
Only issue was the jamming about twice per mag, they were all failure to lock forward fully into battery.
Buffer weight? Spring tension? Tips on determining cause and correction?
The DefendAR15 does have its own buffer tube with a spacer to take up slack space between additional stock length and STD tube length, and never have this issue, same ammo, with stock tube.
I figure there are many here with the knowledge of the system to better help me understand what may be the malfunction, and I get to learn more about it in the process.
