You might already know this, but if you can find a good deal on a used NF or trade your swaro for one, you can send your NF off and get ZS put on it and/or change the reticle. I sent a nxs off that I traded for a couple weeks ago to get a MOAR put in it. They said it would be 8 weeks and it's already back in the mail and suppose to arrive tomorrow. Cost was $370 including the return shipping. Plus they give it a full inspection. Just something to think about. Good luck!
