Front sight post loose? S&W MP15T

[chuckles]

Hello:
I have a new S&W MP15T with the Troy flip-up sights front and rear. My question is that the front sight post can be turned(elevated or retracted) very easily with just light finger effort. Is this normal or should there be a detent or spring to hold it more firmly? It seems that there should be someway to make it a little less loose. Thank you for answering my newbie questions. Nice rifle BTW. I haven't shot it yet, (waiting for my ammo to arrive). Just busy buying more "stuff" for it.:cool:

It shouldnt turn easily. Are you in AZ?

Is there a detent or spring that should add tension to it? It sure seems loose to me. Easily finger turned.
I'm in that desert paradise of western America known as....Las Vegas!

Simple fix. I called Troy and all that is necessary is to expand the tensioning cut to tighten the fit. Piece of cake but I hesitated to do anything until Troy told me how to do it. I'm happy now.:)
