Thread: Omark / Sportco Target action Q?

best to speak to several gunsmiths and get estimates.

the aus army apparently looked at converting omarks to magfeed, but the cost was prohibitive

omarks do have some quirks :

primary extraction is not flash, so if you plan on using hot loads, you may end up running into some issues. there is a fix (weld a blob onto the bolt handle where it cams, and machine it down for correct clearance) but you will not be at the level of something like a barnard

the cross-pin on the floating bolt head is a weak point, to be allowed to shoot on NRA ranges in NZ that has to be beefed up to a larger diameter pin

re-barrelling is the major headache (lugs in the barrel). nielsen adapters solve this issue, but some gunsmiths do not like them as they feel it leaves the tang area too thin.

I suspect you would be better of blueprinting a remington action and sleeving it if you want additional rigidity. more options for stocks and accessories.
