Stay clear - scope is junk, company is worse - Firefield Barrage 2.5-10x40 Rifle Scope

I purchased this scope months ago. It was delivered defective - the elevation adjustment would not work. I got an RMA from the company SELLMARK.NET. I had to pay the $13 UPS shipping to them. They sent a bad product and I have to pay the shipping - Really. After UPS showed it had been delivered back to them I waited and they never contacted me. I eventually wrote to them for a status of my return. They admitted it was defect but had none in stock to replace it. So here it is months later and I'm still waiting. I have no faith anymore that the replacement will even work based up all the lousy reviews it has gotten at so many sites. The company / distributer SELLMARK.NET is one of the worse I have even seen. They rarely respond to email inquires and at this point I'll probably throw the scope in the trash if they ever replace it.
