Marble Arms Bullseye Gunsight?
« on: October 31, 2019, 02:40:07 am »
This looks like a neat concept, particularly on lever guns and older 22 rifles.  I suspect this approach would also avoid the disappearing ghost ring phenomenon.  Not to mention - this is one inexpensive rifle sight.  :hmm

    Looks good.  It did take a little bit of time to get the kiddo to keep his head down, using "V" sites, but he got it quite quickly.

    I wonder how it will work for those of us, astigmatism, who peep sites don't work for?  I can not hit a barn from inside consistently with peep sites.

    I've used a similar sight on an older target air gun many years ago.  They work pretty well at short ranges on stationary targets.  The concept of the aperture sight has many applications over the years including the ones affixed to the lens of shooting glasses as well as gun mounted types.

    I have that problem, though to what degree is hard to convey. The size  and distance from the aperture seems to be the critical factor - even with optical correction.  The forward mounted aperture rear sight, such as found on the WWII Japanese Arisaka, is a good example of this.

    In general, I find Patridge type pistol and rifle sights seem to work best, hence my preference, as noted previously, for the TFX-PRO on Remington open sight slug barrels. 

    Surprisingly, I also find 19th century Block style express sights work quite well.  The sight picture looks something like this: o
    This is the exact sight picture as found on shotguns with a single bead vent rib.  The eye seems to automatically center the bead on the flat.

    The sight picture of a 19th century "Block" express sight and a single bead vent rib are essentially the same. That is why I've oft said if a shotgun slug hits POA with a vent rib, that is really all you need for most hunting with rifled slugs.  Of course this may mean checking POI with several slugs of differing weight and velocity.

    The sight picture is the same as used when checking pattern center with shot - as shown below:
