Oooh, I have one of those.
I keep meaning to order one of the .50 or .625 cal ones, but by the time you start buying the better darts, those get expensive. (more than I want to pay for an amusement piece, anyway)

I don't need .50 to shoot up cans. I have no disillusions about using that thing to "hunt". It's just a fun fucking toy I can shoot inside and laugh like a lunatic while using. But that Cold Steel Big Bore looks cool as all fuck anyway.

Can always upgrade later; the beauty of modular weapons.

I'll probably need a riser mount for at least one of the scopes, too. Eventually will put flip-up BUIS on as well.

I'm already itching to put together another one - I'm thinking 20" with bipod and long range scope.

My new Knights SR15

I am so with Leenetworx, The Modular nature if the AR makes it such and easy platform to work on / play with that Once I build or buy and upper (I always tell my self that I will just run it on one of my existing Lowers and then build a dedicated lower) It is like that first salty potato chip,, and I want more and more. A few weeks ago I grabbed that 22LR Tactical Solutions M$ upper and threw a budget sight on it and plopped it on an existing lower.

Well then I grabbed a Delton Stripped Lower (Not my first choice but the cheapest) an RR 2 stage Trigger group, then a rail system a new T6 collapsible Stock, Blackwater Storm Single point, and to top it off I won a Lucid HD7 at the Friends of the NRA Banquet. (I have to say that while I wouldn't trade my eotech for it this is a Very Nice Holographic sight that can be bought around $200) and here it is today with the Halo on it

The Scary part is that because I liked this one so well, I have a Alexander Arms 17HMR Upper on Order and have started to explore either a 6.5 Grendel, 6.8 or even a 308 build. Damns AR's

:rockwoot:
Very sweet.

I have been eyeing those, too. Cheap ammo FTW.

CMMG has a good one as well
