Hello All,

I have a new Mark lll Comp. Never fired. Installed the weaver rail today. Used blue locktight on the screws as suggested. Looked at the pistol a few hours later and the bolt is frozen, like you can not move it. It looks like it is rearward about 1/32" inch, like it is not all the way forward.

I loosened the screws in the rail, no change. Could the holes for the screws go all the way thru and the locktight has the bolt locked.

Any suggestions.

Thanks Jim

Could the holes for the screws go all the way thru and the locktight has the bolt locked.

It's possible. If it were blue locktite, then you should be able to open the bolt with some effort and possibly a bit of heat.

Have you field stripped and reassembled the pistol? If so, did the bolt work after that?

I have not done anything except install the weaver rail. I used blue, so I'll get the hair dryer.

Jim

Hi Greener,

Owe you a beverage. Hair Dryer, gentle pry with screwdriver, it moved slightly. Then a tug and it came out. Looks like the back screw hole goes all the way thru and too much locktight will lock the slide.

Thanks Jim

Strip it, leave the bolt out, and after you get most of the old loctite gunk out re-do the screws with the bolt out. That way you can get in and remove excess, even though you'll be using less loctite this time.

Make sure you didn't get any of the blue gunk in the spring or any moving parts, of course ... and get that thing back together so you can actually shoot it!

Shooting is far more fun than maintenance, except in crappy weather or days you can't use the range.

80F and sunny, today. Do you mean shooting of taking the boat out might have been more fun than this?

Anything's better than putting in a shower stall.

YES!!!!!, how did you ever find your way up here and get back home?

UPDATE...........................

This morning I field stripped it. The blue locktight did in fact seize the bolt.

The 3 screws that hold the weaver rail on, the rear one goes all the way thru. The front 2 do not.

Thanks for all the help.

Right you are. Those holes are most likely all drilled and tapped when the receiver is a bare tube of steel, as that is the most practical time to do it. It is just easier to drill and tap through holes and not blind holes. Just clean the receiver tube and bolt and you should be good to go.

Yes, doing it the old fashion way. Those kits take all of the work out of it.

Removing drywall in the kitchen ceiling because of the two different leaks. Fitting the 60" kit into a 59.5" alcove. Redoing some of the most ungodly excuse for professional plumbing I've seen. If I hadn't bought the kit, it would have been easier to tile it.

Don't forget to apply a dab of loctite, JLB. After all the playing around in the bathroom I went shooting. I was doing real well until the screws holding my rail decided to loosen up. Shooting was a tad wilder.

My excuse and I'm sticking to it.
