Lots of choices in that range. I've got an Athlon 6-24 and a Vortex 6-24 that were both around $350. Prices seem to be up a bit since I bought, the Athlon BTR at UAT is about $400, but sure nice glass and reticle.
Man that's gonna be heavy unless you go for a LEUPOLD 6.5-20x40 AO if you're lucky to find a used one within budget.
I won't recommend the $229-$260 AIMSPORTS Alpha6 4.5-27x50 which is the clearest bar none Chinese scope I tested In the $650 and under that meets a 6-24x or 5-25x criteria. It may weigh down that already porky HW110.
Besides it's way too cheap and a no-brand to even be believable that it's the CLEAREST $650 and under Even at 27x with a company based in California with a lifetime warranty.
Go buy the Discovery HD or Vector Optics instead they are more expensive at the $350 budget for added piece of mind buying a more familiar brand and almost as clear.
Budk $229 and got confirmation new shipment arrives in a week to 10 days enroute Direct from Aim Sports USA in Cali. who handles the lifetime warranty. They ship UPS express and charge FLAT RATE of $26.99 plus 99 cents insurance (BUY IT!!!) no matter 1 scope or 93 of them (That's how many I ordered since they made me a VIP CUSTOMER with direct line to the head order person in charge to ONLY CALL HER WHEN ORDERING not bad it's only my first order with them and I got them for cheaper since I bumped my 39 back order Up to 80 YIPPIE!!!). I only got 13 in 2 days and 80 more backordered. Backorder free shipping and insurance if you paid and only got partial order like I did. Sales tax is charged.
$259 and change from Optics Planet using their in house 10% off code and free shipping. They charge tax too. Shipping isn't a flat rate though.
I have two Athlon scopes a Talo and a Argos both perform well, all the features you will need. I feel that people over spend on scopes, save the money for another gun.
Just openning up the curtains so people can see the light that's all. When I got my first one I felt like I been really ripped off all my life by most other Chinese scope companies. I used to be a HAWKE and BUSHNELL fanboy. After buying my MARCH-F I thought DAMN it's clear and how many Alpha6s could I have bought instead?
