Whoever at Vickers Tactical that put this together did a great job of video editing!
Ok, it looks like your gas nut is not adjusted properly. What setting was that only when it failed to cycle? You may have it too open and are not getting enough gas to cycle the piston. That look like a Century gun. If so there could be a number of other issues. Is your piston bent? Is the gas block aligned correctly and pinned in place?
My FAL has collected dust for a decade now. I can't bring myself to rip open those battlepacks of ammo I bought for $25, when replacement cost would be $150+.
The DSA FAL Voyager is the same (or close) to the PTRThat was AWESOME!!!!!!!!!!!!
I just bought a PTR-91, basically an HK G3 (basically), and truth be known if I could afford a DSA SA58 I would, but they go for north of $1600... double the cost of my still excellent PTR, and with the exact same capabilities (military style rugged .308 battle rifle, 20 round mags, semi-auto etc.).
