I've personally owned 3 Tract Toric scopes and currently own the 4.5-30x56 model and it's great. I like it a little better than my Athlon Cronus since the glass is a little more soothing to my eyes. Probably couldn't notice any significant difference though if they weren't glassed side by side. The only think I don't like about the Tract is there heavier than average I think it's 41 or 42oz.
I had 2 of the 4-20x50 30mm Tract Torics and parted ways with both of them due to their limited 20MILs of total elevation travel and prefer the Chinese made (GASP) Athlon Ares BTR G2 4.5-27x50s that replaced them which to my own eyes were clearer than the Tract Torics at 4.5-20x magnification and had more total elevation travel of 25MILS and lighter weight too. The higher magnification was a welcomed plus too. In this case, the Chinese Athlon HD glass beat out the German Schott glass in those 4-20x Torics which is why I sent them down the road for a new owner to appreciate. Based on my own eyes, the 34mm 4.5-30x56 Toric is clearer than their 30mm 4-20x50 Toric even though they all use German Schott glass.
Buy them on sale 2x a year next 10% off sale expected in December or LE/Military get 15% off anytime.
I plan to try the Maven S.4 5-30x56 next time they go on sale hopefully under $1400. They're currently $1800 and supposed to be the best glass in the sub $2000 price point. I already own a Nightforce NX8 4-32x50 and curious if this Maven has nicer glass. A YouTuber Panther Hollow with no skin in the game stated his Maven S.4 5-30x56 is clearer than his Tract Toric ELR 4.5-30x56. He was offered it on their loaner program and liked it so much he bought it at full regular price.
I like my NF NX8 4-32x50 better than my Tract Toric ELR 4.5-30x56 due to it's significantly lighter weight 28oz vs 41-42oz and the NF has better image quality for my own eyes.
If you're interested in buying a Tract Toric then based on what I personally owned including some of their competition, I'd recommend their new $1500 4-25x50 Toric next time they go on sale for 10% off in December for $1350 or use your LE/Military discount for 15% off anytime for around ($1275?) Their total elevation travel is insane.
Already gave you my take on the alternatives as well. If you're ok with buying Chinese, the Athlon Ares BTR G2 4.5-27x50 is still currently on sale for $565.49 at Walmart online with free shipping and free returns. Just click on their $869.99 and the MOA model is the cheapest one. They typically sell for $869.99 everywhere else and have a MSRP of $1087.49 and Black Friday sale price has historically been around $670 for price reference.
If you're wanting to pay full price for the Tract Toric ELR 4.5-30x56 for around $1700 then just get the Nightforce NX8 4-32x50 instead.
