PSO-1 sight Battery help....

[spetznaz-47]

Does anyone know what type of modern battery to use in the pso-1 (russian) scope? I bought one and it came with an adapter for a AA size battery but that doesnt work, (3 volt is to small to fit). I know the bulb is 2.5 volt but does anyone make or does anyone know of where I can get a battery to get the rectical to light up? Thanks a bunch if you can help. Oh I also have a chinese version of one also what type of battery does it take if its different? Thanks!

I'v heard that Battery Barn www.batterybarn.com (http://www.batterybarn.com) carries the Tadiran 3.6v lithium AA for less (part# is something like IL-36) but I can't find it on their website, you may have to call them. HTH...

Thanks TOMAC,Ill give them a try.

[spetznaz-47]

Thanks POLYAK. Ill check them out.Do you have one of these scopes? If so how do you like it?

[Polyak]

Yeah, www.batterybarn.com (http://www.batterybarn.com) does have the 3.6volt AA size batteries for $6.95 each, part #AA-3.6V-LI

If order is less than $25 add $4 shipping, if more than, it's free.

I've got one on my ROMAK3. I like the scope a lot. It's not a tack driving precision type scope, having only 4x magnification and a chevron reticle, but it is very effective to say the least. The scope was manufactured for military rifles, not for shooting sub MOA groupings on paper. The ease of mmounting and dismounting, plus the illuminated reticle, add to it's servicability. I originally had the PSO with the sanitized width based range finder. I recently sold that one and bought a military type PSO with the height based range finder. Whichever one you have, they are both great.

Depending on which PSO you have a regular AA battery will not work with the bulb that comes with it. This is the case with the PSO scopes that came with a 2.5 volt bulb. The sanitized PSOs that I have seen all have the 1.5v diode that will work with a regular AA battery. Centerfire Systems has just started selling the 1.5v diodes to replace the 2.5v bulbs, so now all the PSO scopes can now work with a standard 1.5v battery.

If this isn't your problem, explain a little more please.

I am looking for a Military PSO of any type myself. Anyone know where I might obtain one?

Try ClassicArms or Centerfire Systems.
Centerfire's # is 1-800-950-1231
ClassicArms # is 1-800-383-8011

Hope this helps.

The diode is for 1.5v AA batteries but can be used with the 3.6V LI "AA"size batteries.

My romak3 came with the diode and the 3.6V battery. I have PSO scope for regular AK's and they came with the bulb. I replaced the bulbs with diodes and they are real nice and bright with the 3.6VLI battery.

I have a question about sighting in the PSO1's. I have one that came with my Romak3, but the instructions on how to properly sight it in is laughable. Whoever did the English translation needs some help with sentence structures. What is the proper procedure on these scopes? I see three screws on each adjustment knob and the instructions eluded to having to loosen all three on each knob. Anyone have a better, more articulate set of instructions out there anywhere?

Polyak: If you adjust the knobs to get zero, why do you have to adjust the outer cylinder if you first set it all to zero on the tick marks when you started off? I guess these spin or turn real easy and can lose your calibration? As for the bullet weight, I use the new Hungarian noncorrosive 148-gr. match ammo. Stuff's pretty sweet in FPK's, Draganov's, and Mosin-Nagant's. Thanks for your input!

After you zero you scope and set the out cylinders to 1 on elevation(for 100Meters) and 0 on windage if you are shooting at something thats say 500Ms away just move your elevation knob to +5 and you are dead on. Assuming there is no wind. Thats what the windage knob is to compensate but I'm not sure how fast equals what numbers.

[Polyak]

I'm not sure if I understand your question or not. When you go to sight the scope in at 100 yards set the top knob to 1 and the side knob to 0, hopefully the wind will be minimal for you during initial sighting.

Take 3-5 shots, allowing a minute or two between shots, and then move the knobs accordingly to compensate for how far off you were. After you finally have it sighted in, the top knob will more than likely not still be on the 1. Let's just say it now reads 5. So now you are zeroed in at 100 yards but your dial says 5, for 500 meters. At this point you would loosen the 2 outer screws and then holding the sides of the knobs where the numbers are listed, turn this sleeve type thing back to where 1 is indicated at the mark instead of 5. The top part of the knob does not move when you turn just that cylinder part. When the you have the cylinder part or sleeve, whatever you want to call it, tighten down the 2 screws.

Do the same procedure for the windage knob. I too do not know what the formula is to use the windage knob according to the actual wind speed and direction. For calm weather you would want the windage knob set at 0.

I'm glad you like the Hungarian ammo. I just ordered a case of it last week, hope to give it a work out in the next few weeks. I had my ROMAK3 at the range this past weekend trying to do some serious sighting in with 147gr silver tip ammo. I had a very pleasing range experience with the PSO and ROMAK3. I was able to test out to 300 yards and found the 4x PSO and the ROMAK3 to be surprisingly accurate together at those ranges. It has always been extremely accurate at 100 yards for me but I wondered about it at the further ranges using only a little 4x scope.

I was able to put 3 shots in almost a 10" grouping at the 300 yard mark. It shot a little high due to the 3 is meant for 300 meters not 300 yards. I am sure, with more practice I can get better. The 4x magnification becomes somewhat of a handicap at those distances. But it sure is nice to just be able to dial in the range and shoot.

[Polyak]

Only loosen the 2 outer screws on each drum, do not touch the middle one. To zero in, just turn the knobs to where the scope is zeroed in, start at 100 yards. Then, loosen the 2 knobs about 3 or 4 turns and turn just cylinder part of the knob, the part with numbers and tick marks on it, back to the corresponding number that you are zeroing, the number 1. The top part of the knob should not turn here, just the sides. Now your scope is zeroed in and the bullet drop is calibrated for 100-1000 meters using 147 or 148 grain ammo, I forget which is it exactly.

For fine adjusting during the sight in process, loosen the 2 screws and turn the knob just a hair and then retighten, then you have to relocate your tick marks again too. Sometimes the drum's clicks are larger than what you need for fine tuning, that is when you do this.
