Beeman AR2078 CO2 Thumbhole Target Rifle

Lovely wooden stock and very well finished. Diopter sight looks solid. Bolt action is solid

The absolutely useless white seal in the cap of the CO2 tube is embarrassing. It worked the first pair of CO2 cylinders. The first time I replaced the cylinders, the seal actually crumbled and fell apart. I was able to clean out the cap of all the debris that also fell into the CO2 tube itself. Replaced it with a black plumbing O ring which has worked perfectly.

I've sighted it in at 10yds and it's rock solid BUT... the only way I could sight in was to adjust the rear sight almost all the way over to the right. I cannot tell at this time why it otherwise shoots so consistently to the left. I had to tighten the barrel band but that's no biggee. I also tried adjusting the front sight to try and compensate but makes little difference.
Overall, it's a great shooter at 10yds but I'm concerned why the sights need to be adjusted so severely. There's something amiss, I just haven't figured it out yet.

Balances very well for target shooting, being a bit nose-heavy for stable sighting. Love the sound of the bolt action; a great metallic clacking sound. Accuracy doesn't disappoint at 10m. I love the lustrous look of the gun mated to the robust metal barrel and action.

Both original o-rings in the compression tube (on the end cap and the valve at the other end of the reservoir) crumbled after the first 6 shots. They were so old and dried out that they came apart in pieces when I opened the gun up. Replaced them both with Viton o-rings and she's been a shooter ever since.

Be prepared and unafraid to break out the screw drivers, hex wrenches, and other basic hand tools with this gun. The parts are pretty robust, the action is pretty straightforward, and a little TLC goes a long way with this gun.

Pretty basic. Fits well. Like the trigger and the trigger pull.

Include extra o-rings. Bolt o-ring shred with only 100 shots fired. Manual missing a lot of data. Found a good one online for the 2078A. Include rail sight and diopter inserts like the 2078A.

I didn't like the way the stock on the 2078A fit my body but for the same price you get more and the finish is better. Parts are available but $9.00 shipping charges on $13.00 worth of o-rings that weigh less than a dime, on a brand new gun? Not gonna happen. Pyramyd and Beeman should be ashamed of yourselves. I expected more for my money.

Bought the AR2078 for back yard target shooting. I own a couple break barrel rifles and pistols and thought I would try CO2 for a change. I also bought a Beeman QB78 CO2 Rifle for my Grand-Daughter so she can join me with our hobby. I also bought a Beeman 4 x 32 scope for both rifles to enhance its accuracy. Both rifles are set to go, but so far we haven't had time to sight them in. The AR 2078 is a great starter rifle., The wood finish and bluing is real nice and the thumb hole stock is very comfortable. For the money it's a winner ! I only gave it four stars on accuracy because I haven't shot it yet, but if it shoots as good as it looks it should be a cool shooter. This is based on my own review and opinion.

The wood may not come as advertised. It's shown in the magazine as a light grain finish, mine came as a dark wood, but it's still not cheap looking and the fit and finish are real good.

Beautiful wooden stock. Shoots lights out. This is my first CO2 gun, so I did not know what to expect. Nice not having to cock each time, although that was not a big deal. Well put together gun (with one exception). Since it was a new gun, and I am new to CO2, the break-in was interesting. Straight shots, no problem. Load/unload cylinders, no problem. Weight of gun, no problem (excellent)

Seals in this chinese-made gun suck. The cap you screw-on, after loading CO2 cylinders, had a el-cheapo fiber washer in a cut-out for an o-ring. After 2 shooting sessions the reservoir would no longer hold any pressure. Last straw was this morning . . .loaded 2 CO2 cylinders, and immediately I could hear gas coming out. Solution for the cracked el-cheapo fiber washer? Go to Home Depot and in the plumbing department buy a pack of rubber o-rings used for faucets. Turns out that a #11 is perfect. (10 for $2.30) Now I can shoot all day and get full use of cylinder.

Not easy finding an adapter (picatinny to dovetail) that works really well. I am using a Bushnell red dot on this gun (fabulous) . . but adapters are problematic.

Very consistent shooting. Site system is easy to set up. Easy quarter size target hit at 45 feet.

Beeman like many companies have outsourced manufacturing. This Air rifle is an example of that. It is made in China. I would be happy to pay extra for an Air rifle made in the USA. That being said I would change where it is made. Bring back manufacturing or Label in bold on the website country of origin.

at least 50 shots can be made with out degradation of accuracy using two CO2 cylinders.

Extremely accurate! Very flat shooting!

Nothing on the rifle. It comes with 2 Allen wrenches and a T-handled tool, but there is nothing in the manual explaining its purpose.

I did use a plastic bipod when sighting in. With a 10M zero, there is about a 1/2 inch drop at 25 yds. If you have trouble hitting your target, it is you, not the Beeman.

Extreme accuracy . That's how I describ this rifle. Nice wood and blueing. I've never shot through a aperture before. I put five shot in a bull eye mesuring 3/4 of an inch at 55 feet. Add the price point and I can't keep the smile off my face.

Nothing

If your into marksmanship. Buy it.

EVERYTHING. The rifle is very well finished, overall quality is excellent. The only problem I had was that the barrel counter weight was not tight from the factory. When I tried to tighten it, it kept coming loose. A couple drops of blue Loctite and it hasn't moved.

Nothing. I have the .177. I plan on buying the .22

Buy this gun!!!!

Manufactured quality seems good , nice stock , the safety on the gun could be more user friendly, it took a while to site In with a peep sights ,field view with a Peepsight is very poor . 20 - 30 yards you can drive tacks with it.
