Good luck finding one for a decent price.
I bought a DPMS LR-260H last month.It shoots pretty good,I just wanted something for a night time hog/varmint gun.I'll be putting a digital night vision scope on it,along with a suppressor.That's why I bought this model,it's lighter than the bull barrel model,and the barrel is already threaded.
I paid just over $1k for this one brand new.
The factory trigger wasn't very good,so I had it reworked to a 3lb unit,and I had to cut 3 coils off the buffer spring in order for the weapon to cycle properly,and not jam.The buffer spring was too stiff,and the bolt would short cycle.
Other than those little problems,the gun is great.
