Even though my brother digs my two AR's, he still can't get over how EXPENSIVE owning an AR can be, especially if you like to have tricked out gear.
My $900 Bushy Dissy quickly became much more expensive to own as time passed:
1) PRI GEN III tube, $300 (I sold it to get other stuff).
2) PRI FRONT FIP UP SIGHT, $175
3) Sure Fire M962Sxxx 9-volt light with 6" tape switch, $270
4) GGG UFIR Rail, $50
5) About 7,000 rds (3,000 SA plinking ammo, 4,000 XM193 for storage), who know how much I've spent on this!
6) Cleaning equipment (Dewey rods, solvents, etc).
7) Mags...need I say more?
Now, I still want an AIMPOINT M2, a KAC RAS M5 (Hopefully, ARMS or KAC make a rifle length FF rail system ala SIR and RAS II soon), GGG cantilever mount, ACOG TA31 or TA11, and Battlegrip...for BOTH RIFLES! This can get expensive. And this stuff is JUST BASIC stuff. Nothing at all like the TRICKED OUT SPR's types and all out M4-types out there. THEN there's ammo...it's crazy I tell you, crazy...
