Thread: omark trigger adjustment

OK cheers I can do it just was wondering if I had something odd and if there was any particular order it should be adjusted other wise I'll do it and give it a good test before taking it out

I will dig out my old Omark trigger later and identify the various adjustment screws for you. If changing any settings as well as wacking the butt also slam closed the bolt as "brisk" as you can several times. If it survives that you should be good as. Sear engagement is usually adjusted by turning the screw with the bolt cocked until the cocking piece releases. Then adjust back say one turn. There is usually a small aperture for viewing the engagement thru - use a magnifying glass. Check amount of engagement b4 playing with it. In fact, unless there are problems with sear engagement and hideous amounts of creep I would leave it alone. The trigger pressure on Omarks is usually not that light, mainly because for NRA shooting they were limited to a min of 1kg and the spring set fitted was suitable for that range of pressure.

Be careful dry firing an Omark too many times. There is a shoulder on the firing pin assembly that can just touch the bolt head cross pin if no cartidge is in the chamber. Excessive dry firing can crack the cross pin.
