Good accurate sights

[Forum Admin]

Here's some detailed photos of my sights on my .40 cal airgun. I just reassembled the airgun after having it apart for a couple of months. Pumped it up and took a 20 yard shot and put it dead center through a soup can. I spun the can and tried again to see if it was a fluke. Dead center again. That means these sights can withstand some pretty good knocks without drifting. Anyhow, you'll need some sheet steel, aviation snips, small machine screws with matching nuts, a small diameter metal rod, and a drill to make these. I also used some scrap material to shape the sights around instead of using the barrel itself.
Here's some pics of the front sight:



I just cut a strip of sheet metal a inch wide by several inches long. I bent it in half to form the top of the sight and bent it evenly around a piece of scrap barrel material. The top and bottom machine screws hold it securely in place.

The rear sight is a ghost ring type of sight. Here's what it looks like:




It is made like the front sight, the only difference is you bend it evenly over a thin metal rod to make the ring. To sight, you look through the ring, the blade sight should be dead in the center and your target sitting right on top of it. Adjustments can be made by loosening the rear sight and moving it slightly to either side. Elevation adjustment is done by aiming high or low within the center of the ring sight.

Simple, yet effective.  Nice!

What were you shooting?

I was using 55 grain steel slingshot ammo. At 20 yards, they punch through both sides of a soup can and through 3/4" particle board behind it. I've shot them through one side of heavy steel barrels, much like the ones used for burning trash. The 84 grain lead ammo doesnt have the penetration, but does pack more of a punch. One of these days, I plan to clear a 100 yard shooting lane in my property so I can test the longer range accuracy of ammo out of my smoothbores. I can definitely vouch for being accurate enough to hunt small game in 20 yard ranges or less. I'm really looking forward to firing some darts at longer ranges.

i just finished my gun and it shoots quite well. i use a bead sight, that ok?  lucky me there are a few chickens running around near my property lately.
No one is claiming them, so what the heck. thinking of blasting their necks off. Btw, wow  you have one accurate gun there.nice

thats pretty accurate but it would be a pain to adjust in the field...

a couple of years back I was searching for an easy to adjustable iron sights and found this..


no matter how hard I tried, I could never get all the pieces for that windage/elevation adjustments on the rear sights so I use them seperatly. Front-elevation, back-windage but the concept is the same.
I find that ghost ring iron sights are pretty quick to line up but still provide enough accuracy.
I'm still looking for a way to make the ghost ring flip up and flip down so I can use a smaller ring for long distance and a big one for close range.

@fighterace, Yeah, they definitely aren't field adjustable. In fact, once I got the muzzle velocity off the steel ammo, I created a ballistic chart for that ammo and designed the sights to work effectively within only a 20 yard range with as little elevation compensation needed as possible. lol They work well, but if they ever got knocked off line, you'd be up a creek without a paddle out in the field. 

Man, that is a nice sight, looks very effective and could be used on any airgun you build. Nothing wrong with splitting the elevation/windage adjustments between the front and rear sights. All my military surplus rifles work that way.

@josephlys, glad to hear you got your airgun built. A bead sight should work fine, I use them on my Remington 870 express even with slugs and get coffee can accuracy ou to 50 yards. Free ranging chickens... sounds like dinner.  Here in the US, people actually pay more money for free rangers over the ones raised in cages. lol
