I have had a 556 for a while, a decent little SBR if no anything particularly special.

LGS had one with a Troy Rail , one of the STS 081 version SIg RDS,
I picked up for 750.

I think the rifles used to go for over 1000 bucks and the rails were 200 plus.

There are no intrinsic sights using the Troy rail.
They also did not build in the catch for the folding stock.

The stock is length of pull adjustable, unlike the one on mine.

I think I will go basic MBUS sights and AR height RDS on this.

Has anyone found a catch that is supposed to go on the Troy rail for the stock?

Thank you.
