I did as you said and took it apart and compared and everything else works together as it should. It's definitely the this gap between where the spring guide sits and the body pin, the pictures probably aren't doing any justice but hopefully you can see what I mean.

I've had a good look ever it as you said and it seems as though the spring is pushing the actual cylinder out those last 2mm, as there is spring retention on those last 2mm. I might be wrong but it looks like there is a small amount of play between where the body pin and the spring guide sit, if I were to mill out the bottom of the inside of the cylinder, just enough to close the gap so the body pin and spring guide are touching, theoretically it should get ride of the stiff bolt return?

Hi guys, I recently bought an AS01, second hand, to get me started on sniping. It's had some upgrades, some done rather poorly, but I've managed to tinker and get it firing consistently. Main issue I'm having is that the bolt handle doesn't want to return home fully once cocked, not without some elbow grease to return it down. Seems to sit about 2mm further back than it should, still fires fine and once fired the bolts sits back down again where it should be. The only case of this I've been able to find was on youtube (link below) its around the 35 second mark that you'll see the same issue I'm having with the bolt, but the guy who posted the video annoyingly doesn't explain how he fixes the problem, or has replied to any of the comments asking! (Grrrr) The upgrades that have been done as far as I can see are: Upgraded steel cylinder set CPSB steel spring guide CPSB Amoeba piston Lycan Romeo sear Lycan trigger Everything else is stock I believe, any advice would be greatly appreciated, thanks.
