Sounds like you can see the finish line, from where you're standing. And being the first one in .308 - you have broken new ground. I don't know how strong your recoil spring is (or what length) but my M60 springs have just enough strength/length to strip, chamber, and rotate the bolt shut. Only then would it work. I did alot of experimenting using several different length springs (it did incur extra cost) but the weakest/shortest ones worked best, in the end. I had to stack sections together (not ideal) after cutting it too short, then used a new full section, after the best length for function was determined.
Two questions, somewhat off-topic. How would you rate your build, as far as the entertainment/enjoyment/challenge factor? Meaning enjoying the construction process, the build challenges, and your anticipation level?? I think that's a fair question to be asking. Personally, on a scale of 10, I'd rate any beltfed AK a solid 12. Low cost might yield a 13
2nd one - Were you mentally saturated, to where you dreamed about it at night, throughout the process? I did during mine - alot. Thought about them almost nonstop, day & night for weeks on end
Good luck getting that last half inch of travel. Tighter gas system, and lightened BC (made a huge difference here) and charging lever never hurts either. You could always (incrementally) enlarge the gas port, as a last resort
You've done a great job documenting your build. Nicely taken SHARP pics like yours make it more fun to follow. Your build thread has probably inspired alot more builders to jump in, and you deserve the KGB Award (Kommiefornia Gun Builders)
