Barra 400E

I waited a month to write my review, after I had put several thousand rounds through my gun. In my personal opinion, this is the best BB gun I have ever shot. The gun itself has worked flawlessly; the speed loader, however, could certainly be improved. I have shot the gun with several of my older friends, and they also seemed very impressed and will likely be purchasing their own guns soon. I know I will be ordering another gun for family shoots.

Too much fun

So I'm doing my review after 4000 or so shots. So I lasered all the distances in my yard with the rangefinder. I also used a Centerpoint 32 mm reflex sight with the 1 moa crosshair. This gun is too accurate to use a 2 or 3 mil dot. I don't like any Centerpoint scopes, but this sight is great on the Barra. I can hit a tennis ball steel plate at 23 yards every time 10/10. at 45 yards I can hit a beer can on a stick 7/10 times. At 85 yards I can hit a 5 gal bucket 7/10 times,. Obviously there is holdover. And I was shooting semiauto. But with the zinc Air Venturi BB's you can easily see them in flight through the Centerpoint mount. Crossman black widow bb's made one ragged hole at 10 yards but are not visible in flight. I just ordered some ASG bb's and read they are the best, we will see. Fully automatic is too fun, and never jams. I prefer semi for just plinking. I also put one drop of Kroil (silicone version) in every bottle of bb's. and shake it for about a minute. It makes the speeloader perform almost flawlessly. If you don't, the bb's will jam in the speedloader and you will swear and write bad reviews on the speedloader. Trust me this works phenomenal, in fact Barra should encourage it. This gun is more fun than I could have ever imagined. Just get it. Now Barra, please make a Ruger 10/22 version, semi auto only. Get me 500 fps and the same accuracy and I will be elated.
