Browe Combat Optic 4x (BCO-005) with 7.62x39 red chevron reticle and A.R.M.S. QD mount. This is the older version made of titanium instead off the current aluminum version. Uncommon reticle but should work with fine with supersonic .300BLK.
I’ve had this optic for several years but it has minimal use. It’s seen maybe 500 rounds on a Sig 556R. Spent a lot of time in the safe. I’ve traveled with it a couple times. It has the same eye relief as the 4x ACOGs and I just can’t make peace with it. Great glass. Auto adjust brightness of the reticle works great. I had a windage turret that froze up so it went back to Browe. They took care if it and it now sits in factory fresh condition and unused since return. Comes in a Browe pelican case.
$800 or I’d trade for a TA11 3.5x ACOG. I’d prefer the .223/5.56 reticle rather than the m193. Red or Green Chevron, maybe a crosshair. Let me know what you’ve got.
