Upgrading Your Ruger® MK IV™ 

Love my Black Momba, hands down my favorite .22 platform in my collection. It truly is a tack driver!!

Save the parts you change out and you end up with 2 guns. Lol

Like to see a review on the 10" barrel for the Mark IV w/velocity tests loading with CCi ammo.

Nicely done ✅ Thanks for the good info and Amazing 🤩 Products

Any plans for mini mamba uppers?

Do the uppers come in stainless or silver? I have a stainless Mark IV target. Everything you showed is black anodized. Paul

I've recently read on some forums (out dated by a couple years) that the Volquartsen competition bolt doesn't operate well in the stock upper. Can you speak to the validity of this? I'm wanting to start customizing my Mk iv tactical, but can't afford a few hundred on a bolt that might not operate even as well as the OEM due to tolerances or whatever and might be better with just upgrading the bolt internals. Any insight about how well the bolt functions on original upper is much appreciated!

I used the accurizing kit with the extractor and firing pin, solved my light strike ,ejection problems(old firing pin showed some peening from dry fire I'm assuming) love the light trigger now although getting all the parts in was fiddly. Interesting idea to have multiple upper/barrels, easy to switch and use same lower receiver in all, some sports require iron sights only, but prefer a red dot when possible-like the idea that 4 inch barrel with red dot can be as accurate as the 6 inch with irons

what does the upgraded trigger do vs the kit without the trigger? Can you use the stock trigger with your sear?

Can I use the competition bolt and accurizing kit in a standard mark 4? And In California?

Do you have a distributor in Finland?

Too bad the optics ready is out of stock rt now

I have been shooting Ruger Pistols longer than you have been alive. Coon hunting shooting raccoons out of tall oak trees. How much better can it really be? A couple new Mark IVs are fantastic. Let’s meet at the gun club with some Ben Franklins.

But the looks of that bolt , looks like a 1930 design

The 22/45 Lite is ILLEGAL in Washington because it has a threaded barrel….
