I just got off the phone with Jarrod and he said BM's policy is to now charge full shipping on all orders.  I am very disappointed to hear this. (For those that dont know you use to could call BM and for small parts like a front site post they would stick it in an envelope and only charge a buck or two for shipping but NO MORE!)
So can someone recommend another source for the extra(.40) tall front site post like the one that BM sells.  And yes I already know that I really do need it.  I am not so poor that I can not afford the shipping but paying 6.50 shipping for a 4.95 part sucks. So until I change my mind or find another source I will just live with my current site turned all the way out.    Thanks
And A big thanks to all the companys that keep shipping cost reasonable like ADCOFirearms and GPSS.  

DPMS has them

Did you put on an ARMS #40?  Bushmaster told me I needed it, but I checked around and most said I didn't.  I put it on a RRA M4 Entry and I didn't need a taller sight post.  It sighted in just fine.  Actually, I don't think I even needed to make any adjustments to the front sight.

J&T has the posts, give them a shout.

Yea, Ipam using an arms 40 and I have to adjust/screw my front sight as far out as possible for it to be right. I can get by fine with it as is but it would look more correct with the taller sight.
