Beeman 1073(RS2) owners

If I may, since MichaelM adjusted my trigger for me I confess it took me a few shots to adjust my brain to it, but that happened quickly enough. In stock form the second stage had quite a bit or pressure and sometimes I'd have to concentrate hard to force a gradual pull. Now, when I've taken up the first stage I feel the firmness of the second stage, and know that release is "right there" waiting for me to decide to shoot.
I have to say the trigger on the model 1073 feels very nice after Mike did his magic. My made smaller groups today than ever, and I can see what the rifle is capable of; easily producing tight ragged holes. 
Some deal, eh?

Darryl glad the trigger adjustment helped!! we could have worked on it a bit more and got it even smoother... I just dialed it in to "close" it had ALOT of creep on that second stage all I really did was adjust a bit of it out....

now we just need to get a tune on that gun you will have to drag it up here and spend an evening drinking a couple beers out in the shed!!! (hope you like really hoppy beers... all I have left is my last batch of IPA's I brewed...) Heck bring the wifey we can throw the womenfolk in the house so they can gossip and complain about our silly hobbies and we can drink a few beers and enjoy quiet out in the shed with a couple cold ones LOL!!!

[darryl]

Home brew? Sounds intriguing. Oh, what sort of tune did you do on your 1073? We'll have to try to work out a visit. Maybe before our next meet?

Yea I been brewing for about 3 years now.. great hobby!

as far as the gun short story is I did everything short of custom spring guides LOL

complete debur
cocking slots polished
honed compression chamber
turned down front of piston and polished
buttoned piston
polished tophat
fitted stainless thrust washers
ground spring ends flat and polished
fitted piston seal (still a bit tight needs to take a tad more off it but...)
recrowned muzzle
Trigger group completly torn down, smoothed out and polished(that was a lot of work those folded and stamped parts where ROUGH!!)
polished slot and sides of anti beartrap/auto safety arm
then of course put back together with JM's heavy tar and moly and other lubes where proper
pluss whatever other small odds and ends I cant think of off the top of my head

I got about 10 or 12 hops plants in my back yard, who do I mail the flowers to? Cascade, Golden and a few others.

Hey guys,
The 1073 being what it is (and you all know it better than I do) is there anything in that rifle that could take a mod that would boost it to over 900 fps in .22? I mean I seriously don't have a clue, but like I always say (wait for it...) "if you don't ask  they can't tell you No". I suppose if it was possible we'd have read about it by now. Huh?

PS hey Mikey, how 'bout scouring that brain of yours to see what you can come up with.

[bart the fart]

my rs2 only came with the .177 barrel and man it has some real POP! what i dont like about it the trigger...the first stage has this super long creep to it and the second stage is this hair trigger....i hate it but this is the best i can get it set and drives me nuts....i've seen tear down rs2 sites that tell you how to do it but i'm no gunsmith...i'll probaly trade it to my uncle for car work on my 1966 amc marlin

[darryl]

hey Bart,
Mike adjusted my trigger. Maybe he can shed some light on taking that hair trigger off. My secon d stage is not a hair trigger, but it's light. The great thing about it is that I can hold light pressure on it until I'm ready to shot, then it's just a matter of a bit more of a squeeze and it's " on the waaayyyy!!".

Hi there, sorry to bring this back from the dead but it has only been a couple months...

I just picked up my RS2 from Wal Mart a couple days ago and having only shot a few "real" airguns before this, I can say I'm pretty impressed at the overall quality and the first impression.

I was waiting for a price drop on the 1072 at Academy from the stellar $129.00 so I could use the gift card my parents got me for my birthday when I stumbled across it on my way out of Wally world for $98.00, and they even accepted my Academy card making it $68.00 out of pocket.

I have been browsing the web for tips about tuning and came across this thread... I was wondering if anyone would be so kind as to post any of the detailed info on what they did with their RS2's to enhance it's capabilities. What lube do I put where when replacing the stuff that came from the factory?

I read someone made their own stock, and reading MichaelM's extensive mod list inspired me to take the plunge. I think a good place to start would be trying to comprehend what all those neat-sounding things on his list are, lol.

[MichaelM]

hey hopper welcome!!!!!!!

Congrats on your purchase!!!

FIRST of all before you even think about tearing into these guns you need to read any and all material you can find on tearing them down!! a good place to start is in the GTA library

http://www.charliedatuna.com/airgun_docs/Fast%20Dear%20Tune%20up.doc
http://www.charliedatuna.com/airgun_docs/B-4-2%20TuneUp.doc

are two good resources... now the guns are different and have have newer synthetic seals so the parts about care and feeding of older leather seals dont apply but it will give you a decent idea on what goes on  in the insides of these things


Second......and MOST important..... these guns are NO JOKE on the inside..... the spring  that powers these monsters CAN take your head off....  eyes and such are no match for these things and if you want proof I can post a few pics of what happens when accidents happen and your face gets in the way of one of these springs.......

YOU HAVE to use a spring compressor and you need a few good handtools to do it right or dont even attemt it!!!


Third... have fun!! lol if your decently mechanicaly inclined its a fun job and project!! I never get tired of working on guns!!! if you run into something you dont understand stop and come on here and ask questions!! there are a TON of knowlegable people on here and collectivaly the amount of information available is mind blowing


once again welcome and if you have any questions feel free to ask or fire off a PM and I will be more then happy to help out where I can!

[hopper]

Hi Michael, thanks for the welcome and the reply!

I am pretty mechanically inclined and I have access to a lot of good tools, I am a car guy by nature and I'm no stranger to springs or spring compressors and the damage they can cause if not used properly.

I own a couple firearms that I take down and care for regularly, so I have a set of more specialized tools for this purpose as well, if I can make use of any of them.

I'm hoping to end up with a fairly quiet gun that is as accurate as I am, and I want to do it the right way Thanks for the info, and any new suggestions would be well appreciated.

[bart the fart]

hey michael today is the day!!! i'll ship later today....i know, i know its been awhile, but life got in the way....welcome to the forum hopper! i grow hops too! i'm sending my beeman out to him to tune it for me and he charges a good rate to tune it! enjoy the gta ...i sure do! bart

[MichaelM]

other then screw drivers and other hand tools there isnt many of the tools for your powderburners you want to use on the RS2.... do NOT use metal brushes/rods in the bores of your pellet rifles.... the barrels are not hardened like a powderburners barrel is and you will wear the rifleing right out of it... instread either get you a pull through (like an otis system ir such) or make yourself one (alot of people use a length of weedwacker line with a blob melted at one end then basicaly thread the patch onto the line and pull it through..... believe it or not this works REALLY well lol and have one in my shooting box...)

just a couple patches with goo gone and then a few dry patches and your good to go.... and dont worry about cleaning the barrel till your accuracy starts to fal off and that could be anywhere from 500 to 5000 pellets depending on the gun and the pellets etc etc LOL.... MOST (not all) airrifles seems o shoot better with the barrels leaded up a bit.....

never drop any petroleum based oils into the compression chamber.... it will deisel and or detonate and thats not a healthy thing for the gun

as far as lubes go.... moly goes good on about everything LOL, pivot points, rub points, pistons, seals....   if your keeping stock springs and guides then alittle heavy tar on the spring and guides will help alot on cutting down the spring noise and vibrations....

I know some guys like dieletric greases for the piston seal or a dielectric/moly mix and they seem to be getting good results... I personaly have not messed with it but I do believe I will look into it here soon

I am also a big fan of silicone for alot of parts that need to be protected but doesnt need acoat of oil al over it like trigger groups and such....

 ahh... well anything else  just ask LOL

Oh and cool Bart!!! I didnt know you grew hops!... thats like 3-4 people in this thread alone that either grows hops or brews beer lol!!

and I will be waiting for your girl to get here!! now that we have a short break between holiday madness

[supertiger]

anyone know where I can get a seal and spring for my 1073? Power has been dropping off and it's down to 610fps so I'm getting up the nerve to take it apart and find out whats going on inside.

[hopper]

hey supertiger, how long have you had the gun?

I grabbed some cheap .22 ammo from Walmart last night and shot up some old signs leaning against the fence last night. I was standing right outside the window and I asked my fiancee (inside) if she could hear me shooting - negative. So I guess the neighbors won't complain. They may start to wonder what is up with all the squirrel and grackle carcasses piling up in their yards though...

[showguns]

they are good shooters ,I just sold one at gun show  for 100 dollars about 35 dollars less than I paid for it. because I new they are selling new at wal mart for 98 dollars

[supertiger]

had it about a year (1500 shots). I noticed power dropping off lately. Read here to change breach seal. Picked an o-ring outof an assortment and got back 50fps...shooting 660-670 with Crossman HP 14.3. Before I started reading this forum I used to lave it cocked for long periods waiting for Mr Raccoon to raid the garbage. A lot of times left it cocked overnight so figured I killed my spring. Ordered a "universal Chinese" spring from JM.

Built a spring compressor and got it apart today. Looked pretty good inside. A couple of rough spots I cleaned up with a file and 400 sandpaper. Pulled the new spring out of the package and its much longer than the original!! Anyone out there used this spring in RS2 or TF 89 etc.?? I read here it would work but surprised how muck loger it is than stock.

[MichaelM]

http://www.airrifleheadquarters.com/catalog/item/251488/6825218.htm

thats the spring you want to use

[supertiger]

OK perfect, thats the one I have. It"s a couple of inches longer than the one that came out. Maybe because I left it cocked for long periods so it got shorter. Did this spring improve velocity? Any tips for compressing it and getting it in? Used the 4 bolt method to get it out on the Beeman Rs2 Sportsman. This is my first airgun dissasembly. Any advice appreciated. Trying to figure out how to set the bolts in the right position so I can get the trigger and pins back in once its compressed.
