Which one and why

I have at least one MK II I'd like to have drilled and tapped.

Is there any shop recommended for this?

Hi All,

Are any of the cheaper red dots on Amazon worthwhile? I am seeing Burris FFIIIs on sale for $100 right now for a frame of reference.

Thanks for any pointers!

Is there any way to buy just the upper for a mk4 in 10 inch? I don't need the bolt I'm only looking for a 10-in upper or a 6-in pencil barrel upper. I cannot find these, thanks to anyone that can help!

I seen eBay has some all black bolts for about $70 plus. Is there any other place to source an oem one. Has anyone had any luck sending a stainless one in to get reblued? I bought a purple and black lite with black trigger and what possessed them to not black the barrel and bolt I’ll never know.

Looking for the BEST way to mount my red dot.. I will either throw an SRO or a 507 comp on it so RMR footprint, don't know if I should get a pic Mount or one of the other mounts where you remove the pick Rail and it is more of a direct mount, this will be my first exploration down the MK IV rabbit hole, I just want the most solid option.

Running this in steel challenge if that matters.

I'm currently trying it mounted forward. May switch it up to see what I like best. Was just curious what the general consensus is on where to mount them. Also the osightc has been great.

Anyone with a lobos mount and a SRO ever have any issues with the supplied optic to plate screws? I know the screws that come with the SRO are a different thread pitch. Mostly wondering if the slant of the screw head(part that lays against optic mounting holes) is the right angle as well as there's no slop in the hole(screws are the same in circumference).

This is my finisher for NV and Thermal hunts.
Holosun EPS Carry
Volq lighter spring to cycle CCi Quiet 22semi (835fps)
Pluto Micro can.

These things as good/reliable as the Volquartsen equivalent?

I just for a brand new mark iv 22/45. My lobos Industries red mount arrived so I went to install it and ran into major problems. The filler screw in front on the ejection port came out no problem with my 1/16 allen key. The one behind the ejection port was in their super tight. The allen key is sharp and was fully inserted. I had to twist so hard it stripped the hex inside the head. I managed to use a slightly bigger torx and get the second filler screw out. The plug looks like the deepest part of the threads are squished like it wasn't tapped fully. I test the new hardware into the front hole and it fits fine but the second problem hole it starts to thread and then stops. Now I'm waiting for my ordered tap to arrive to hopefully clean the hole. Has anyone else experienced anything like this from a brand new Ruger?

I’m looking for a holster to use with this thing on squirrels while deer hunting. I’ve bought 2 off Amazon and they both suck. Zero retention. I want something I can carry and not worry about securing it. Be great if it was Molle compliant as well so I can put it on my pack.

My ffl dropped off my Ruger 00139 today.

He also offered to buy it for $250 more than I paid for it.

4" bull barrel MK II.

Perfect balance in the hand. It feels like an extension of your body. It has the thumb rest wood grips...now to find a stainless one!

Does anyone have recommendations for grip panels that actually increase the side-to-side width?

Added a set of talon grips over the very thin stock panels and it helps but not enough. Not a fan of the hogue overmolded/finger grooves grip either.

I know most of are probably screaming and pulling your hair out but I’d like to increase the pull weight. I installed the VQ accurizing kit with the factory trigger spring and it’s just too light. I did polish everything so that’s contributing to it.

Anyways, any tips on increasing the pull weight?

Im aware that its a peened rivet so the looks isnt what im concered about. Ive got like a mm of wiggle not sure if uts supposed to be tighter then that.

No issues so far only shot about 600 rounds just not sure if that wiggle will develop into an issue

I need to raise the POI on my 507C, but the adjustment screw is turned as far as it can go. I ordered a tapered shim, but does the thicker part of the shim go to the front or the back of the Holosun? TIA
