Fullfield E1™ Riflescope 6.5-20x50mm

The 6.5-20x is the big boy in the Fullfield E1 family, and allows for some seriously long range hunting and shooting. 

This Fullfield E1 model has side adjusting parallax focus.

The Balistic Plex E1 MV reticle is custom designed for this scope. MV stands for Milling Varmint. The holdovers are designed specifically for .22-250 rounds, and are mil-based. It means this is a great choice for coyote hunters, prairie dogs and similar varmint hunting. 

The scope focuses down as close as 50 yards, though, which makes this one popular with precision .22 LR shooters.

The riflescope is resistant to a lifetime of field use, heavy recoil, and harsh vibration. It is protected by the Burris Forever Warranty™.

Fullfield E1™ Riflescope 6.5-20x50mm is rated 4.6 out of 5 by 178.
Rated 5 out of 5 by from Perfect compliment After reading reviews and seeing the E-1 at a local Sportting Goods dealer, I picked one for placement on my CZ FS 550 in 93 x 62. I wanted an optic that provided large field of view for better pick up of game, sufficient variable power to assist my eyes for shot placement, yet compact enough to be in balance with the carbine length CZ. My friends and hunting partners have all handled this rifle at the range over past four months, all of us agree a near perfect match for firearm balance, good eye relief needed for this medium/big bore, and on how they like the E-1 reticle, independent magnification adjustment, and above all clarity of the scope.

Rated 5 out of 5 by from Great All-around Hunting Scope I have owned a Burris Fullfield E1 scope for a couple of years. I have used that scope on a couple of guns and absolutely love it. I'm a hunter, period. The 3-9x40 has been on my muzzleloader and on my 30-06. The scope is always clear and is built like a tank. I opted for the regular plex reticle, as my guns shoot pretty flat for the distances I hunt. I hunt with guys that are colored ring scope believers and my Burris gives as clear and sharp an image as any of their scopes that cost twice as much. I love my scope so much, I just bought two more identical E1 3-9x40 so I could mount them up and leave them. Burris scope with Burris rings on the guns I depend on.

Rated 4 out of 5 by from Great hunting scope This scope is a entry level scope that packs serious clarity and low light capability. I used it for 2 years in all conditions. Up in the fog it tends to lag behind some of the higher end scopes for moisture resistance. Then again that can easily be fixed by a hydrophobic coating. The one true gripe I have is the reticle is a little thin. In low light and in the timber its really hard to locate. If It was similar to the veracity I would be much happier. This is only a problem for people on the west coast timber hunters. Roughly 1 month ago I fell down a embankment and totaled the scope so we will see how the forever warranty experience is. I'll update with a time line.

Rated 5 out of 5 by from first rate 20X scope Here is a photo of the scope mounted on a 6mm Ackely Improved. A worthy addition to Burris mounting hardware would be extension Signature Ring-mounts for Ruger M77 actions. I used whatever what would work best and that unfortunately was not Burris. Signature mounts having the inserts are probably the best mount system available for most standard rifles. I zeroed the rifle in at 300 yards using the 3rd bar down or the 300 yard hash mark. At 100 yards I was about 1 inch high and at 200 yards 2 inches. My load was a 87 Vmax at 3350 fps. I was easily able to see the black steel target that was partially covered by dried mud and dust. Adjustments were what I expected, 3/4 inch at 300 (+-)

Rated 5 out of 5 by from I have used this particular Fullfield E1™ Riflescope 6.5-20x50mm burris - Fullfield E1™ Riflescope 6.5-20x50mm for over two years on a custom hunting rifle and it has by far became my favorite scope for hunting purposes. several hundred rounds through the rifle with this scope and not one regret ! My Longest Deer shot thus far is just under 400 yards and I would not have been comfortable doing this shot without the reticle this scope features and knowing my trajectory data for my loads. Excellent clarity and repeatability for this optic every time. this was definatly worth purchasing. I hunt hard and don't use cheap stuff because it just cant handle the weather and normal use I give the equipment so this is a 10 in my book.

Rated 5 out of 5 by from My 6th Burris Rifle Scope! Fullfield E1 2-7 x 35 is a perfect fit for my CZ550FS rifle in 9.3x62mm. Have always been happy with Burris. Fullfield E1 is worth the price difference over Fullfield II, given the rear focus adjustment. Power wise, fyi, I also have Burris: - (II) 6.5-20 power on a .204 Ruger - (II) 2-7 power on a .243 youth rifle - (E1) 2-7 power on a 7mm-08 (replaced a Simmons that broke) - (E1) 3-9 power on a .300 WSM - (E1) 3-9 power going onto a .35 Whelen Also have purchased Leupold (x4), one Nikon, two Bushnell (one of which would not zero and replaced it with a Leupold), and three other Simmons that haven't broken yet. My Uncle's 1954 Model 70 in .270 Win is getting a Weaver 2.5-7x32. All this just to show that I have selected Burris more than any other brand. I always look at Burris first when selecting a new scope. Only go to Leupold or Nikon if Burris doesn't have the power range, size or features I'm looking for. Have been at this seriously for 35 years, so put that in perspective.

Rated 4 out of 5 by from Great scope. So far,so good! Seems to be better quality compared to the Fullfield II. I've had a couple of Fullfield II 5 years ago and had to send them back because both couldn't stay zeroed in somehow. I've decided to give Burris another chance and the E1 impressed me. The only reason I didn't give it 5 stars is because I would have liked the "etched in reticle" to be a tad bigger. My old eyes are not as sharp as they used to be.

Rated 4 out of 5 by from Excellent Clarity I bought this scope at a local retailer on 40% off clearance sale. The glass is excellent; focus is perfect from center to edges. Brightness is excellent also. I have fired about 100 rounds with the scope, and it holds zero. The only reason I am giving it only four stars is because my scope has 1/2" clicks at 100 yards. The manual says 1/4" clicks at 100 yards. I called the folks in Greeley, and they said it was impossible that my scope had that mechanism in it. Well, I have been shooting a number of rifles and a number of scopes for almost 50 years, and I am telling you this scope has 1/2" clicks at 100 yards. No two ways about it.

I have the 4.5-14x44 with the E1 ballistic Plex reticle and for the life of me I cannot find where you indicate the power the reticle is calibrated for. I see high mag and low mag for the Plex section of the reticle, but nothing for the drop/wind section.

Asked by: Jm12301
Hello, That scope is calibrated at max power.

Would the turret cap from a Burris C4 fit on the Fullfield E1? Big fan of the C4, except for the AO...would be great if I could order a C4 turret to use on the new E1's for elevation adjustment. Anybody know or tried this yet?

Asked by: BRvalley
We can absolutely make a turret for you to fit the E1. You are correct, the C4 and E1 use the same turrets/caps.

I have the Fullfield 4.5-14x42 long range moa. I have it mounted on a winchester .243. How do I find ballistic charts for this reticle/caliber to create dope cards.

Asked by: akmoxie
Hello, You can use our Ballistic Tools program for dope cards. For the reticle, simply compare it to your ammunition's ballistic chart as the reticle is already in MOA increments.
