With a 350ftlb limit you'd have to keep a 125gr down to around 1130fps or for something heavier like a 165gr around 970fps.

Both are easily achievable using N310 but would it be enough to cycle the gas piston?.

I'd need to be sure as there's no way I could justify spending £2000 on a gun I could only use outdoors maybe 10 times a year.

it can be done-using gas regulator like on AK GN60 or Dragunow,with 2 settings,small hole for full load-bigger for lower pressure,but...if you mess it up on range...your bolt will park in your skull one day?

On a Dragunov there are two settings on the gas regulator, one is for shooting normally and the other is used when the rifle is excessively fouled and cleaning is not possible and when shooting at high altitude in very mountainous areas.When the SVDS (folding stock version of the Dragunov) was developed the gas regulator was deemed unnecessary and was omitted on production versions.The Polish Wz(GN)60 and Yugo M70 AK variants have a gas cutoff on the gas block but this is purely to facilitate the launching of rifle grenades.AKM's and AKMS's fitted with a PBS-1 suppressor use subsonic ammunition but still have a standard size non-adjustable gas block.The Wz and M70 are the only AK variants that spring to mind that use a gas cut-off.

Thank you, I aim to please ussrflag

Heres one I knocked up from a Saiga, fitted with original Soviet laminate wood, GP-30 grenade launcher recoil pad, PK-A red-dot sight and a rare 30rd aluminium paratroopers magazine (these were experimental and not widely issued).This one was sold to finance an AKMS underfolder.
