Question: Can this rifle be charged from compressed air source?
Document: Extremely accurate! After sighting in, my 1st 12 shot group measured 3/8" ctc from 10m. My expectations were met. Be careful filling with co2, if you don't follow the directions and disconnect the fill hose from the air rifle while under pressure, it will make a big "bang".One "problem" I found with the gun is that the sites kept loosening and falling off. The problem was that the open sights support two types of gun rails by flipping a small piece of metal in the mount.
I have to preface this by saying that I'm not particularly experienced with air guns. I've got a few cheaper air guns as well as a Crosman 2300S pistol (which took me three tries to get -- see my other review) and a modified Crosman 1377. However, this is the most accurate and easy to shoot gun that I've ever used.I started shooting at 10m air rifle targets scaled down to 6m and I was already doing much better than I had previously done with my cheap Crosman multi-pump (760) and springer (Gamo Little Cat).It feels great to hold, I really like the sights, and the trigger seems excellent (for my inexperienced finger).
this gun is amaziiinng it is extremely accurate and can take out raccoons and squirrels and of course crows. i would recamend this gun to any one who wants to spend alot on pellets gun but if u dont want to spend alot get the rugar air hawk and the the crosman 1377 pump pistol for 48 dollars and u can kill squirrels
Lost a star because the insert in the front sight should have thinner lines. The accuracy of the rifle is better than the sight will allow
This rifle has improved my daughter's overall 3-position score by at least 20 points. I can not believe the accuracy she is getting! She has qualified for the varsity in her high school JROTC marksmanship team.
This rifle meets all expectations for competition in the sporter class of the NMAR. It's extremely accurate at. 10 metersAnd the finish is great for a RIFLE of this price. I would certainly recommend it for anyone interested I 10-meterCompetition.
Simply better than any other Sporter Class rifle. Can adjust to a 12&#34; length of pull to fit my 9yr old shooters. Daisy rifles don't do that. This rifle can compete against Precision class rifles and shooters. Use compressor to blow out degassing port the first time before you insert the degassing tool, mine had some burs in it that got caught in the degassing tool threads. Eventually got it out and all is OK.This ain't a toy. Use for indoor target shooting only.
Great rifle for son in his first Sporter rifle match 10m. Still looking for pellets it likes to shoot the best, but certainly easy to adjust and shoot. Adjusted the pressure, trigger weight, first and second stages of the trigger easily. The issue was it arrived poorly packaged, basically just loose in a very torn box. Fortunately the rifle was in perfect condition with no issues. What was missing were the user manual, allen wrenches, degassing tool and the apertures for the front sight. The sights were already on the rifle, which I thought odd and had one aperture in.
The has lived up to my expectations. 10.9's on a scale of 1 - 10 for sure!Now... to figure out how to get the funds to get 10 of them for our local NJROTC team!
The breach is definitely a standout -- compared to the other Crosman guns (and my other guns), this gun is very easy to load. The long, thin probe along with a flat surface allows the pellet to slide into the barrel without any trouble.If you are looking in this price range, I highly recommend this gun.Update (8/26/2013): see image above.
