Thanks for all the assist guys. I think I may have also found part of my issue. The OMW spring obviously has more coils in it, but it is also about a coil and a half bigger than the stock spring. So like the breech ring, I think the issue is that little bit of extra. I think if I knock off that extra coil I will be OK. The thing already has a brand new OMW 2x catch in it. So it should have the strength.
@ozn_rfherd, that sounds really cool but what would the cost be and shipping stateside? I would love to give something new a shot but for the parts described I don't think it would be very beneficial economically (depending on your answer, I maybe wrong)
It does cost to ship stateside, but not as bad as shipping out of the states that's for sure.
I can get a 500gram satchel to the states for about 20 pacific pesos ($AUD), and for the first time in a long time the exchange rate is in your favor.
Where we can help is with combined shipping, as we are pretty agreeable that way.
I'm just not so sure cutting coils off your spring is desirable...after all it is an OMW product designed for the purpose, not something from the hardware shop.
What do you mean by "a coil and a half bigger", length?
