1.5mm Wall Tactical .625 Cal Muzzle Guard Peep Sight By Venom BlowgunsTM Compatible with Cold Steel MagnumTM and Venom BlowgunsTM 1.5mm Wall Blowguns

Haven't used this yet but I know that it is gonna work great.

It lives up to the description, and fit my .625 bore blowgun. Though it was a bit loose, I used a piece of electricians tape to make it snug. It definitely improves accuracy.

Mejor de lo Esperado

Was a bit large but with some fletching cement fit just fineThe Cross hairs look really awesome on the end of the blow gunThe actual help with aiming is minimalBut does help a little with vertical alignment

Three stars because I can stuff tape around it so it can fit my 5 foot .625 blow gun as it was too big. I thought to myself maybe it will the professional 4 foot version which i have purchased as well not the case as its too small for that. I figure if you sell the product make sure it does what it says its supposed to do. I should not have to pad it with tape to get it to fit.

I don't mount this upright on the top of the barrel; It's mounted about 50 degrees to the right. This way I can shoot with both eyes open still and the X of the cross hairs settles right over the middle of 'both' barrels (as seen with eyes open). Reasonably tight fit, but can be bumped by accident, of course.

I found that this was not very helpful and I prefer the muzzle to be unobstructed...but that is pure personal preference

I was very happy with the product overall but I did not like the fact that it spins on the end of the blow gun; so it never really stays aligned for sighting purposes I'm sure I could come up with ways to make it stay permanently but unfortunately that would not allow me to put the piece back on for a walking stick definitely does help when citing targets though if it doesn't move
