when i sanded the opening i took off BARELY any material.. and it seems like it slides fine now...
dunno..
You don't have to take much off, what matters is where you take it off. I put my Saiga gas tube by my AK74 gas tube and noticed the subtle difference on one or two angles on the face that slides past the lever.
I took off a little at a time until it would go completely in.
If you get it right you should be able to push down and then just barely forward and you will hear a click noise. I think it is the spring locking into place.
