Bolt Sticking

[Ada Bita BdC]

When i play, when i shoot quite fast. My bolt doesent want to return back, so i either have to get my battle swab and push my bolt back then it fires fine. I read up and it said to drop a schim down into the level 10. It worked fine for a bit, later that day it started sticking every 3-5 shots. The bolt just doesent want to return back. Do i need to drop another schim? Or whats the problem. my level 10 seems to be tune fine with the x-vavle. Is there something im missing?

use more oil on the carrier oring, and a little pbgrease on the bolt stem. Or your carrier is a little too tight. you could also try a larger spring, that would increase the return force on the bolt.

you know what always fixes it? tighten the field strip screw with an allen wrentch. snug it up pretty tight, but dont strip it.

Shims don't help with the bolt sticking on the bolt return. They only change the point of venting when the bolt hits a jam.

The bolt sticking is usually an indication of a carrier that is too tight. Try going to the next larger carrier.

An easy fix in the short term is to move to the shortest bolt spring. This allows more air pressure to be released from the chamber more quickly. The result is that there is less of a restricting force on the return stroke of the bolt.

also check your velocity. i noticed that at really low velocities the valve would do this for no reason

well i dropped another schim down there, and it seems to work. returns fine no sticking or nothing. as in the oil part i have slick honey on that; the best lube in the world. velocity is shooting at 280-286. so i believe it was the schim part. so far so good
