At 71, I'm new to "adult" air guns, and new to this forum, so this is my first post. I'm a retired tool&die maker, with a shop, and shooting range, in my garage, and a bit of an amateur gunsmith.
I have a Beeman RS2 Sportsman with two barrels, .177 & .22. Is there a way to remove the front sight, without destroying it?
I'm guessing it is glued on, or maybe pressed on?
I tried search; couldn't find the right thread.

Welcome to the forum.

I *think* on that rifle you can simply use a wrench wrapped in a towel to turn it, that should make it loose enough to pull off with your hand.

Most front sights are merely press-fit in place.

Try using an adjustable allen wrench with a single later of cloth over the barrel to avoid scratches, loosely fit the allen wrench over the cloth behind the sight and use a mallet on the wrench to tap the sight off.

I don't have this model rifle, but the Chinese-made Beeman's are likely like all the rest, so this should be the best way of getting it done.

Thanks for the reply, but did you mean crescent wrench?
If the front sight is pressed on, I thought I'd hold this (removable) barrel in boiling water first. The plastic should expand more than the steel. Or, maybe use hot oil, to avoid any chance of rust. Or heat it with a hair dryer?
The idea is to get the sight out of the way of the laser, and dress up the look a little bit. At my somewhat advanced age, open sights are no longer an option. The laser is an experiment, and I have a Leapers scope on order.
I never used a scope before; the Beeman scope had too much paralax error for my close range shooting.
A book with an exploded view would be a big help. Any suggestions?

I'm sure he did mean crescent wrench - I don't think adjustable allen wrenches are legal in California.

You can use cloth, duct tape, whatever it takes to keep the sliding wrench from scratching the metal finish. I don't believe you need to mess with heat or lubricants to get the job done. If it's overmolded or pressed on the method Eric described will work.

Did you order a scope with an adjustable objective lens? That's a great feature for correcting parallax at the variety of ranges in the airgun envelope.

I used a block of wood to tap mine off. I have a crosman storm xt. I am pretty sure yours is the same way. I just cut out a mallet shape out of a piece of 2x4 and tapped carefully.

Welcome aboard, I don't have a lot of advice though... Neutral

I always say "Everything fits with a hammer" but I'm not sure that would do you any good. Mr. Green

That whole "heat it up" concept is BS- never worked, never will. Someone started repeating that on the internet years ago, and it just won't seem to die off.

Really, go ahead and try it- then when you move on the the wrench/mallet to get it off, you too can be an ambassador for the "stop posting crap" movement! Mr. Green

A "crescent" and "Allen"wrench are the same thing- Some guy named Allen apparently invented it. For some reason, seems different regions use different terminology for different things- for example a "Robertson" screwdriver vs a "square head screwdriver" (which, by the way, is a superior screw to the flat head or Philips/star head screw). Some regions have some really messed up terminology- one I heard a couple years ago was "screw nail" when basically they were talking about a self-tapping woodscrew- but that was VERY regional.

Yes. I got a Leapers Golden Image 3-9x32AO Rifle Scope, adjustable down to 5 yards. That will be fine for shooting in the garage. Being new to using a scope, I had to learn what paralax error was.
I think it was a factor in returning the .22 Walther Talon Magnum; I never could get satisfactory groups. I tried 5 different pellet weights over two days of testing, and got tennis ball sized groups at 25 yards on my back deck. The furnished scope had no paralax adjustment, and I had to keep re-tightening the mounting screws. I really wanted to like that gun, but I returned it for a Gamo Whisper trade-in. That was the recommended replacement from the online retailer. I'm still evaluating the Gamo. Probably most airguns in that price range wil have some minus points. It is .22 caliber, and shoots dime sized groups at 30' with most of the pellets I've tried so far. For now, I have a laser sight. The scope may improve the group size somewhat. From what I read, The GRT3 replacement trigger won't fit the new Gamos, so I may have to make my own.

A Crescent wrench is an adjustable spanner made by Cooper tools under the Crescent brand (now used generically to mean adjustable spanner). An Allen wrench is a hex key made by Allen Manufacturing, and also now taken generically as a hex key.

However, Eric's point about regional differences is completely valid. A Crescent wrench can also be called an adjustable spanner, shifting spanner, shifter, fit-all, adjustable-angle head wrench, Swedish key, English key, or French key An Allen wrench can also be a hex key, or a zeta key:
http://en.wikipedia.org/wiki/Adjustable_spanner
http://en.wikipedia.org/wiki/Hex_key

The whole Robertson vs. square drive thing was because of patent disputes and marketing rights in different countries. (The Phillips head is involved in the whole mess, too):
http://en.wikipedia.org/wiki/Henry_F._Phillips
http://en.wikipedia.org/wiki/Robertson_screwdriver

For more regional differences, let's not forget monkey wrenches and Stillson wrenches.

So, back to the front sight - use an adjustable spanner, and forget the heat.

Don't get me started...Calif is now proposing banning the open carry of UNLOADED guns. Sucky state for us second ammendment supporters.

I heated the front sight with a hair dryer, and tapped it off with a mallet and an adjustable allen/crescent wrench. There was minor damage. I replaced the front sight with a black Delrin (plastic) sleeve I made to the same diameter as the barrel. See pix(I hope). Then I hand filed a radius on all exposed edges of the breech block. They were sharp enough to cut you, if your hand slipped. I'd eventually like to radius the top of the breech block to match the air chamber; it will add a clean, sporterized look to the finished gun by removing all of the rear sight mount

A very tidy installation. Now that we know you can make stuff we'll all be looking forward to your next project.

A very nice solution. I'm with Slavia on what he said. Wink
