Modifying a bolt release on a P14/M17
Guys have a delema

My ruff but hopefully reliable 600 OverKill is nearing completion, just needs final machining and a last alround clean up and blast before the cerakote, then off to the stock maker.

The problem we have is this. The rear of the bolt stop/release was cut off and a small part of the action was machined off.

I was told that you could remove the rear of the bolt release spring, machine the rear of the action off and it would still have enough tension to stay in place and function as normal.

Well it dosen't it has a good 1/3 of and inch of slack and freely pops in and out

SO what am I missing here, what else do I need to do. If you look at the second photo you will see the bolt release sitting out away from the action it only has tension from this point onwards.

I think I might need to tig or brase a 90 deg return at the back of the release to apply pressure/tension

You are correct. The 90-degree piece is sometimes attached to the side of the receiver, sometimes it's formed from or attached to the rear of the leaf spring. Either way, you need an adddtional piece to provide tension.

What I do is heat the spring and bend it 90-dgrees so the end is supported by the receiver itself. It's really easy to do. Get a spare bolt release, make a .250" bushing that will fit into the release which you'll use as a mandrel to bend the spring over. Put the spring onto the box, put the screw through the bushing, heat the spring red hot and bend it around the bushing, then trim the spring to length. From the picture I see you'll need a new spring to do it; that one is already cut too short. This method doesn't provide as much force as the original but it is certainly enough to hold the bolt in.

Solder a leg, either on the spring or receiver, to make it have leverage Good luck

Tin Can, rear sight is From talleys custom shop, you tell them how high you want the rear block and they will machine it to your specification. We got this 1/2 inch high, and have machined the base for height and contour, there is still some final tunning, when we fire it. The base block needed to be drilled and tapped , but once set, might get a soft solder.

Sight is easily removed by twisting the knob on the side. It has windage adjust ment but no elevation. It's not a Standard rear base, they have machine a flat into the side to anchor the peep with the screw.
