Title: 392 Pistol Scope/Relief?
Post by: WolfyW on April 12, 2015, 04:40:43 PM
Howdy, folks. I have a 392 with a good barrel. I have a home made adapter that allows me to add rings, Weaver-style.
I'm toying with the idea of buying a pistol scope and mounting it scout-style. What kind of eye relief should I be looking for when considering a pistol scope?

Most pistol scopes have enough relief for a scout mount. I've got a Swift 4X on my 342 Benji & a Simmons 4X on my Blue Streak, both scout mounted. The trick is having a good solid mount that won't cause barrel separation & you can still hold onto the scope with one hand when pumping up the rifle. I got the mounts from Mac-1 Airguns. http://www.mac1airgunshop.com/product-p/iashba.htm (http://www.mac1airgunshop.com/product-p/iashba.htm)

I like that setup, Dave. Thanks for the pics! Looks like you are able to pump the rifle just as if it had no scope. That's what I'm trying to accomplish .

Have done the same thing with my 397 and Blue Streaks, but use either a 2x pistol scope or a red dot up forward on the barrel, given that I do a lot of offhand shooting. I like leaving the receiver area clear for the sake of gipping when I pump.

Ya, I'd prefer to pump a 392 that way as well. Tried a red dot awhile back. Maybe should have went with a different brand? I used a Tasco and POI was changing. I assumed from the impact of the pump arm?

Too bad the Crosman barrels aren't the same O.D. as the 392's... I'd love to use that base!

More likely, parallax.

What I've discovered with red dots at short ranges, 10 to 20 yards, is that there is definitely some parallax, some models actually having a lot of parallax. Rest the gun so it can't move, center it on the target, then move your eye right and left. If that dot moves off the target, you have some parallax.

One way to fight this is use the front sight on your rifle, assuming it is visible in the red dot. If you are careful to center the red dot over the top of the front sight for each and every shot, you've eliminated the problem. Might be worth a try. Really made a difference for my 10 meter shooting when using red dots.

All great advice, and much appreciated. The other problem, hence the scope interest, is my middle-age eyes. No experience with pistol scopes to date. But if there's one that can be mounted far enough forward to allow for gripping the rifle and pumping it traditionally, I'm all ears. But mainly need to know if 10-12 inches of relief will work, or is more needed?

Either one of my scopes provide enough eye relief & allow you to pump the rifle in the traditional manner. One hand on or near breech & the other on the pump handle.

This one might work for you. I have one mounted on my 1377.

Not sure if you are interested in this or not but I used an air venturi intermount when I had one, and just used a traditional 3-9x40 scope and it was a rock solid set up I liked it a lot the way I pumped it was I put it upside down on my right shoulder and set the barrel near the front sight on my shoulder and used a downward pulling stroke to pump the rifle and grabbed my pistol grip with my left hand and I found 8 pumps for extended shooting sessions fairly easy. That's just my $.02 but I hope whatever you do you like!

Interesting. I've pumped it upside down over my knee. Will have to try your method before making a decision.

Here is a pic of my setup:(http://i1341.photobucket.com/albums/o752/brandynbanville/Mobile%20Uploads/IMG_20141106_2121393102_zpsxnlkvqyr.jpg) (http://s1341.photobucket.com/user/brandynbanville/media/Mobile%20Uploads/IMG_20141106_2121393102_zpsxnlkvqyr.jpg.html)
It was a solid shooter I took a Hosp with it at 40 yards sitting on my butt the day before it's demise (gun not bird) :'( I wasn't sure about how the hunting crowd was here so I cropped the two rabbits out of the photo as best I could but both were taken @30 yards with this setup and it was a 397 not 392. The demise I was speaking of was I was apparently running the gun dry because the piston stuck but I continued with my downward stroke not knowing it and I snapped the lincage between the piston and pump arm  :'( :'( that will show you what ignorance does but that does support the strengths of my pumping form I guess ( I  am 6' and all of 170 so no physical speciman by any means but I like to think I am fairly strong) I have since moved on to a new air rifle after selling the broken Benji but I plan to get a 392 someday in the future.  I will never run a gun dry again on the plus side! Sometimes learning hurts  :'( hope you like the setup you choose!
