Fullfield IV 3-12x56mm is rated 4.6 out of 5 by 47.
Rated 4 out of 5 by from Clear glass, Bargain priced! Best scope Ive found for under $200. I purchased the 2.5x10x42mm with the non-illuminated reticle. Nothing too fancy, but has clear glass, plenty of eye relief and seems to hold zero after a full season of in/out of a rifle case, bumped against a tree trunk, beat around in the brush etc. Elevation and windage clicks proved accurate. Happy with purchase. I did need to mount it with hi-profile rings for adequate clearance but that may not be the case with all rifles (savage 111 w/flat back in 7mm rem mag)

Rated 5 out of 5 by from An Amazing Scope I had purchased a Fullfield 2.5-10x42 and somehow the turret covers and battery cover was cross threaded. Don't know if this was done at factory, missed during inspection or what. I had to use pliers to remove all the caps. I left a review about this that wasn't very good. I want to retract that review now. I went ahead and purchased another in a 3-12x42 and it's perfect. The caps hold tight but come off easily when needed, battery cover comes off easily. It appears with the other scope I just got a bad one. This 3-12x42 Fullfield IV is amazing with really good glass and a very nice amount of eye relief. It checks all the boxes for a very good budget scope. The illumination is great too!

Rated 5 out of 5 by from Clear glass, excellent reticle Just got my new Burris 4x16x50 illuminated scope for my Sako. Bright, clear glass and excellent finish on the scope. Love the dial settings on the Illuminated reticle vs. other brands that have to hold the button. Burris, please include scope lens covers.

Rated 5 out of 5 by from Bright Optics I had been looking for a scope with a 56mm Objective and they were either extremely expensive or cheaply made. this one is equal to or better than any Léopold I have owned. Bright optics Great Eye relief Good Eye Box.

Rated 5 out of 5 by from Great varmint scope I got this for a 204 Ruger varmint rifle. The glass is clear and the illuminated reticle is not so big ad to obscure the target. I like the relatively open top for a clear view when scanning the fields. No problem with holding zero although the 204 isn't exactly a hard recoil round. The 30 mm tube and big objective allows me to hunt every minute of legal light. I'm very impressed with this scope and feel that it is built much better than other scopes in its price range. The only complaint that I have is that it didn't come with any lens covers or a sticker for my safe door. But that's so minor I'm not taking any points away.

Rated 5 out of 5 by from Seriously impressed. This is the first Burris product I ever purchased. I can tell you it certainly will not be the last. I bought this to put on a .17 HMR What a fantastic scope. Everything is smooth, no gritty feeling, amazing clean clear glass. For an inexpensive scope I was blown away. Now I just have to decide what model in going to put on my 6.5 creed.

Rated 5 out of 5 by from Great quality and affordable price I bought this scope after I had two cheaper ones break. It’s crystal clear, love the long range reticle. Sighting it in was super easy. It’s got very definitive clicks when you adjust it which I really like. Definitely worth my $250, will be buying a couple more.

Rated 5 out of 5 by from Excellent scope that can do it all Beautiful scope and like described on social media, the optic clarity is excellent for the price. The E3 reticle is perfect. It doesn't interfere with your target. The design is slick and high quality. But I must admit the magnification adjustment is pretty stiff. Not forsure if this will get better overtime. I hope Burris will adjust this then this scope would be flawless.

At this price point, I was a little disappointed to discover that the Fullfield IV 4-16x50 does not come with scope lens caps. What is the exact size lens caps required for eyepiece as well as objective lens?

Does the 6.5 Creedmoor reticle work for a 308?

Asked by: mattyram
The center crosshair will work but the holdovers will be off. You can still use it though, we recommend a reticle analysis to see where your drop points line up. https://www.burrisoptics.com/ballistics#:2

On the left turret of the scope what is the purpose or use of the white colored adjustment dial?

Asked by: Turret Use
That's your parallax adjustment. Parallax adjustment is a feature available in nearly all modern rifle scopes. The effect of parallax is presented when your reticle appears out of focus with respect to your target, and to the focal plane of the scope. Although generally not an issue at ranges of less than 150 yards, it can greatly alter your point of impact at longer ranges.
