Your MCS T4A is an awesome stock.
You are right about 2 things:
#1 - The clamp should not be that difficult to lock on your T4A.
#2 - Yes it is tough to diagnose w/o getting a chance to racoon it.
My guess is that either the crossbolt hole is out of alignment with the clamp which would allow the outside shell of the stock to put things in a bind
or
Some of the adhesive used to anchor the clamp into the stock was allowed to migrate into the slot running down the long axis of the clamp body. That would retard the ability of the clamp to flex close and open.
If you would like to have it looked at you are welcome to send it to the KMW shop on my UPS account. I would sort it out and get it on the way back within 1 business day. I am 110% sure that MCS would be happy to handle any issues with it as well but I am not going to volunteer their commitment in this thread. I just know them and know that they want customers happy.
If you decide to pursue, hit me at
[email protected] rather than this forum please.
Be safe.
