You might want to see if the AWB expires, then you should be able to get an M4 carbine with a real telespoing stock instead of the lookalike.
Check out Rock River Arms also- they have a really good reputation and are alot less expensive than the bushmasters. I was going to buy an AR this year, but I decided to wait out to see if the AWB would expire and not be renewed so I could get some cool extras on my AR. I' ve got an M1 Garand on order now to hold me over until then
