Will the largest size stretch a tiny bit more to fit over a 64mm (OD) scope? Burris Fullfield 3-12x56.

If you heat the rubber sleeve with very hot tapwater for 1 minute, it might permanently stretch 2 mm in diameter. If it tears, you lost $14. If it works, you saved the expensive price of the correct Burris sunshade. A bit of Vaseline smeared on the inside front of the rubber sleeve will also help. You need 3/16" clearance between the scope outside diameter and rifle barrel to fit the sleeve onto the scope.

Will this fit a vortex crossfire2 3x9x40?

I don't own that Scope but if you measure the end of your Scope and send the correct size it should match your Scope well.

What is the actual length of the product? All that is listed is the package length.

Overall length = 5-1/8" . Effective sunshade length = 4-1/4" to 4-3/4" depending on how far you push the shade onto your score. Outside diameter at joint is 3/16" larger than sunshade.

Can i put a flip up cover at the end? what is the od of the 43-48mm unit?

Yes You can, well at least I could with the size that I needed. I've got the Konuspro Scope and the objective lens size required was 43-48mm Monstrum Flex Sunshade, so I ordered the Monstrum Rubberized Flip-Up Lens Cover. Your size would depend on what size the end of your Outside diameter or you scopes Objective lens is. Measure your Objective scope in. There is a chart that breaks size down, listed with the Monstrum Product. I hope this is helpful.

Great sunshade, great fit and function

Great price point. The fit is nice and tight and the overall design and function is great. Fits snug and didn’t impact any visibility.

Finally, a shield that works!

I tried for months to find a sun shield to fit my scope with no luck. When I came across this product, I thought what a great concept! I ordered according to the size chart, and it fits perfect! Looks great and great quality to boot. Finally, someone had the smarts! I would recommend to anyone needing one, you won't be sorry!

Does the job.

It fits well, and does what it is supposed to. But if you bump the scope, the sunshade often gets knocked out of place a bit and needs to be pushed back on. Not a big deal. I’m still happy with the product

Works as a sunshade

I needed a sunshade for an Athlon Talos BTR 4-14x44 scope, and this fit. It's not a long term solution as if you pack our rifle on or in a rucksack the shade wiggles loose and comes off of axis with the scope bell. In the rain the rubber wasn't tight enough to not let water inside, so if you are using this product you might want to attach the shade to the bell with some duct tape to secure it in wet weather. Is it a great value? No, it's a piece of plastic tube and a piece of rubber, but it does the job. If you don't have the option for an aluminum screw in shade (Athlon was out of stock for the Talos) then this will work until you can get a better shade.

GREAT

Excellent for a $15 fix. Quite sturdy and a good option as no one makes a sun shade for my 50mm Vortex Crossfire II scopes. I do not bump my optics, so movement is not an issue for me. Looks quite decent on scopes.

Very cheaply made

Very cheaply made and also very easy to bump it and have it fall off. And the inside is a gloss finish instead of a flat non reflective surface. Inside is also a high gloss finish instead of a flat non reflective surface. Sort of defeats the purpose of using a sun shade. Definitely would not buy again. It's very easy to bump this piece of junk and get it slightly out of alignment as well.

Sunshade fits very snug on scope. Be sure to measure your scope before ordering,there are 3 different sizes available. Good product!

Solid piece. I was worried that it would be too flexible but it is a perfect solution to a bent objective bell that prevented a screw on sun shade.

Fit the scope perfectly. I wish there was a broader range available. Only beef is the price, for what it is.
