I have got what you desribed off gun broker for about $350, but condition has a lot to do with whether you got a good deal. I also throw away or give away scopes I get. Slings are cheap.

Is it a chinese bipod? Or Harris?

I have bought a new model 10 heavy barrel for $425 from Cabela's, out the door.

The value is going to depend on the add ons. I bought a Ruger 10-22 out of a pawn shop because it had a Vortex scope worth as much as the gun.

I bought an AR 15 for 500 bucks with a 200 Timney trigger...

Did you shoot out the barrel on that AR?

The bottom line, is shoot the rifle and enjoy it. I like shooting my bolt rifles more than my AR.

If you like the rifle, then I like the deal.
