I've had these in the parts drawer for a while now, so I'm offering them up as a deal for someone. Front and rear sights - the front is the normal height for handguard mounting. Black matte finish. These flip up and lock in place, and then fold with a push button, so you're not going to fold them accidentally. I like this design because they have a knob with click detent for windage adjustment, so no tools required to adjust left/right at the range. They're $90 each from Midwest Industries new, so I figure they're worth half in good used condition. $90 local pickup or $100 shipped.
Sorry for the blurry second photo - my iPhone skills are weak. I bought these from a big name retailer so you can be confident they're legit. I'd say condition is 9 out of 10. I take paypal or USPS money order only. Post with any questions. Thanks.
