I'm still waiting for the rest of the pictures. I know that someone must have some!

Go get some and take some of your famous pics.

I think you have seen these but I will try and take some more today

I only have a regular SIR, and I think this new one looks as if it will be light years better.

I love the new SIR they are sweet and I feel this one is going to be a winner and 2B will have a hard time with the supply and demand on this one.

Did the big brown truck come and see you yet?

Yes it did.

Question:

If I intend to install one of these on a new STAG lefty I'm planning to buy, how should I order the rifle?

I intend to install an Eotech 553 and flip-up front and rear iron sights.

Thanks in advance.
