Ruger MKIV complete bolts on Ebay for $30....fits MKII AND III as well.

Looks like Volquartsen selling take off bolts on Ebay. They say these work in MMKII and MKIII pistols as well. These are complete units.

They have closeout $19 triggers too.....cheaper on Ebay, than their own website clearance.
They also selling takeoff adjustable rear sights for $12.

Picked up a MarkIV bolt with their upgraded firing pin and extractor already installed for $50. They sell those two parts for $32 on their site. Great deal! will have to keep an eye on this seller.

Is the MKIV bolt an upgrade over the II III?

[Sheldon]

It is a one piece. On some of the MKII pistols the grip portion is a welded on piece and can eventually break off. One of mine did that. Ruger did and will replace one like that under warranty. I thought these were a good enough price to mention as a spare to have if wanted, especially since it's complete with extractor, recoil spring, firing pin, and pins and such. I shoot mine enough to have worn bolt parts out. Ruger is great for replacing them but having them on hand while the replacement parts come is nice. Less down time.
