highwall stock interfering with hammer fall (Read 70 times)

	Hi, I have an original DST highwall that functions perfectly without the buttstock attached. I'm currently trying to get a second hand buttstock fit to it. If I attach the buttstock and tighten the screws, when I pull the trigger the hammer falls to half cock. If I take the screws out of the buttstock and try to pop a primer, I get a light strike, but the hammer does go all the way down. Is it likely that the stock is making contact with the sear? I can't see it affecting the fly. I can't find any areas of contact, and I don't want to have the hammer fall onto the half cock notch too many times. Any thoughts? Chris.

	I had a rifle that did something similar. It would slam fire with the stock on but worked fine without it. In my case the stock was pushing on the knockoff spring. Some judicious carving cured the issue. Make up some inletting black (see recent thread) and coat the spring and possibly the sear as well. Jack

	Thanks Jack. I hadn't looked at the knockoff spring. Maybe I'll try to make some better inletting black. I'll have a look at that thread now. I've been using red lipstick. Chris.

	Chris, What's probably happening is that the long tailed sear is being pushed down by the stock. The cut out on the underside of the stock where it butts right up against the receiver needs to be deepened and made longer. The stock that you're trying to fit now has probably been shaped for the shorter sear needed for a single trigger. If you have another rifle fitted with with wide spaced triggers that you can remove from another rifle, you'll be able to see the difference in the two stocks. A closed coupled set trigger stock will also be the same as they both use the long tail sear.
