Rk,
Perhaps i am misunderstanding. When you raise the take down lever, yourasie a little bit and lift the top handguard and gas piston. The gas piston has a very small hole on the receiver end and a large opening on the front site end. If you raise TOO far the OP rod will eject out towards the handguard. I can think of only one issue when going through this in my mind. The lever block is interupting you from raising the handguard. The op rod is now FLUSH with the handguard and will not allow you to rotate back as the op rod is in the way. Thats a dang tight situation bud!!!
I know it can't possibly enter into the gas piston area. The only possible I can think of is its resting position of not allowing the op rod to reverse. HMMMMMMM....can you get ANYTHING to fit in between??? Dental pick? (probably bend anyway)
I assume I would be intersted in forcing the Top handguard up to releive pressure. It may feel awfuly strange but if the rotating block does not get in the way ofliftingthe handguard I would say that would be idea #1 (wait that would be Idea'r #1 - joke, get it?)
Lost at the moment. Was happy to recall the '69 Albanaian in the safe
so I took a peek !
If you need furhter help shoot me a PM and maybe I could look at my 59/66's and hack em to see if I can replicate the issue and solve. Your cost? 3 hand wipes as 1911Crazy had me moly most of my SKS's
