Sight Help Needed

[88redryder88]

I have a bushmaster xm-15 with an "A2" upper. I just bought a
stripped flat top upper. Im planning on going with an EOTech
sometime soon. As for now just a BUIS. Is there a difference in
The FSB of an A2 vs Flat top upper? IE; will i get the right sight
picture through my irons and a good co-witness with the
EOTech? This is my first AR and Im still learning so Please
bear with me. :)

Bushmaster makes a taller front sight that will make up for the difference. It's .040" taller than the normal Bushmaster front sight.

Price: $5.50
Part No: 9349056-M

So I will need a whole new front sight? or is it just the post its self?

Thanks, I was kinda worried about it. Wonder how much I could get out of my A2 upper? only has about 100rds tru it.

Are you referring to the upper receiver itself or the upper receiver and barrel assy.? If it's just the upper then not all that much. Just depends on who really wants one. A new Bravo Co. M4 upper is 109.95 complete.

I know that, I just purchased an upper from them last night. I was wondering what the3 resale value of an A2 upper was minus the barrel assembly, bcg, and charging handle.
