Sorry Doug, I inventory every piece of 5.56 brass that I have, (Last count 1,237) and won't part with any. Remember, if your rifle is chambered for .223, do not use any 5.56 in it! Conversely, if your rifle is chambered for 5.56 you can also shoot .223 through it. Good Luck!
Not out west, and not exactly ammo, but my local gun store (I usually go in just to sneer at their prices) actually had Varget in stock, I got 2#'s, and it was $32 a pound. Also picked up some cast .45 boolits for the six gun. First time in 6 months they have had anything I wanted to buy.
Mine is the Ops version, and HERE is a link to some installation pics from mine. Click on the PDF link in the first post. For the original barrel nut removal, I think I used a BAC wrench, (big ass crescent), and a dead blow mallet and one whack was all it took to loosen it. Hope that helps!
