Excessive cocking Beeman RS2 Dual Caliber

[fr33z3rburn]

I bought one of the Beeman RS2 dual calibers (model 1073) from wal-mart to tinker with, and I think I need some help here.  I am 6'4", 285lbs, and played offensive line in college.  Now, I'm not in the shape i used to be, but my god I can't cock this thing!!!  It's tough, but one handed I can cock it most of the way, but no way no how can I cock it that last little bit that engages the safety.  I HAVE to use two hands to get it latched.  This can't be normal, right?  The first thing I did after unboxing the rifle was to disassemble and inspect.  Everything looks cool, but im no expert.  Advice?

-Thanks

You got a bad one, those are Chinese guns, take it back and get a German or higher end Crosman gun from anywhere but Wallyworld.

I have one and at first it was difficult to cock. I stripped it, lubed, tuned, cropped the barrel (.22), and put a muzzle break on it. It will wear in. I did find it was packed pretty heavily with thick grease...and once I treated everything with moly....including polishing and putting moly on the trigger wear parts, it shoot pretty well...and I get about 815 fps with CPHPs in .22.
I am not quite as strong as you, but I use two hands to cock it also.

Ryan, how far down did you dissasemble your air rifle when you were checking it out?

just because it is a chinese ag does not make it bad I have seen some chinese ags shoot circles around some of the higher class ags, we do not bash or talk about what people shoot on the GTA  if you are not a  fan of chinese ags stay out of the chinese gate sir.  David

Yep.I have one of those and its an excellant shooter.Was a bit stiff but got much better after shooting to break it in.I would take it down to see if anything was broken or damaged,at least exchange it for another.i use the .22 cal barrel on mine.

If you check my sig, you will see that I own an Air Arms TX 200 MKIII.  I understand that this $98 Beeman cannot in any way compete with my TX 200.  That is why I started out by saying that I bought the rifle "to tinker with."

Brett,
I took the "action" out of the stock.  I wiped excessive lube off and checked for sawdust/metal shavings.  Everything looked good from that standpoint.

ddgrego,
I find that this is an excellent shooter as well.  It is proving to be accurate with a wide variety of pellets.  I have taken it down, but have found no noticeable damage.  I too am using the .22 barrel, as i prefer the .22 to the .177.

I would love to see a picture of your chopped beeman.  I may just have to live with the 2 handed cock (lol).

I think I may run another 200 or so pellets through it to see if it smoothes out.  I think it may be time for me to build a spring compressor and start trying to do my own tunes.

thanks all!

I had a beeman .177, sporter gun single stage trigger that would bite like that.  I found the piston digging into the cylinder wall...could be a reason?

Don't know if your AG has the same internals as this one had... the one I had the piston had a stem that inserted into the trigger block...could be off center and not properly inserting into trigger block... thus the difficulty?

Also know that metals shavings will do the same thing...whether from the factory or self inflicted... Time to open it I would think.

It's just a bad gun I own a RS2 and love it.I would return it and get a new one.

I removed the auto safety on my RS2 for that very reason. 
They are great shooters when you get em right!

Update:

I am now in the 250-300 pellet bracket.  The cocking effort has eased up quite a bit, as I am able to completely cock the rifle one handed.  It is still quite a beast to cock though!  I disassembled the rifle again to check for any obvious signs of damage and did not find any.  However, I did notice that the cocking arm is quite loose.  With the barrel fully extended, tilting the gun left or right you can hear the arm flopping around.  Could this be my problem?

Looking more like I need to exchange and try again.

As I have said before, the gun is quite accurate despite the cocking problem.  Paired with a Centerpoint 4-16x40, it is making one ragged nickel-quarter sized hole at 15-20 yards with 15-20 rounds.

Thanks Again
Ryan

Ryan, with that scope that gun should do less than a dime sized group at the range you stated. Is the trigger hard to pull and have you checked for loose stock screws. Mine would work the screws loose very quickly until I put locktite on them. Before I gave mine away using a bugbuster 3-9x32 we were getting 1/2 inch groups at 35 yards with the .177 BBL. My friend loves it and can't believe the power and accuracy of it.  Fun gun but I hated the stock style and it felt very toy like to me. I am around 250Lb myself and never had a problem cocking mine. I really think you need to return it.

Edit: OOPS!  I see you are like me and like to shoot 20 shots before calling it a group. That's a good set then, I was thinking 5 to 10 shots.

33z, - I bought one about 2 years ago, and from WalMart also. (Nothing to do with Walmart of course) - While I could cock it, it required quite an effort. To the point that it took the pleasure of of using it, - so I took it back for a refund.

[Lambchops]

You must have bought a dud. Don't listen to the guy bashing Chinese guns and Wally World. I'm 6'5" 240 and cock it with one hand easily. Its a great gun. Just return it for a new one.

[fr33z3rburn]

DMikeM,

After my initial dis-assembly and inspection, I used thread lock on the forearm screws.  They were quite tight when I disassembled the rifle for a second inspection, so I think I'm good there.  The trigger was fine out of the box, and with some minor adjustments, has turned out to be quite pleasant (Other than side to side trigger slop). 

Lambchops1493,

Thanks for the input bro, not worried about one person's crabby comment.  I think you are right, time to exchange the rifle.  Such a shame.  So accurate and I just got the trigger where I like it.  Not to mention the 250-300 pellets I wasted!!!

I'm leaving town early tomorrow, so it will be 3-4 days before I can get to the store to exchange, but I will update with any further complications (if they arise).  I very much appreciate everybody who took the time to provide input and I look forward to sharing with ya'll in the future.

Had a similar experience with mine.  With information from this site I was able to make it an excellent shooter.  I went completely through mine, the piston had gouged the action in a few hundred pellets before the teardown.  After deburring, cleaning and inspection it was in serviceable condition.  I had alot of slop in the piston, so it got sized with some buttons.  The barrel needed crowning, did it simply with emery cloth and a pencil!  I also went through the trigger.  It was good, now it is something to behold.  I got rid of the 'side to side' slop with a couple of fabricated thin plastic shims.  After a proper lube and assembly it has become an awesome gun.  Don't have a chrony, but it hits alot harder than my B-26 and is every bit as acurate, even with cheap pellets.  I didn't like the stock, made the gun clumsy for me to shoot.  My brother loves it, fits him perfectly.  We regularly shoot together and the RS-2 performs on par with the B-26 (Mike in Iowa product) and my self tuned S1K.  Stick with it.

Have a safe trip.

Here are a couple of pics of my RS2 with the slightly chopped barrel and added muzzle break. I only shortened the barrel at the point where it was choked by the front sight. I then recrowned and added the Beeman muzzle break.

Cocking arm is loose on mine too.

There is definitely something wrong with the gun.  I have had 2 RS2 sportsmans and though I am a fairly large and strong dude, it was never even slightly difficult to cock the gun one handed for hours of plinking.  It definitely gets easier with some break-in and getting the technique just right.  My last rs2 was a gift from a friend of mine who loved his so much he thought I should have one too.  He is about 5'8" 130 lbs, and not particularly strong (he struggles with my p17 and my Ruger Mk1 springer pistol), but he cocks and fires his RS2 without any issue for plenty of long shooting sessions.  I would go ahead and send the gun back for repair/replacement.  It seems like something should have shown up when disassembled, but who knows.

Oh, and for the loose, rattling cocking rod, just wrap a little electrical tape around the rod, and it will hold nice and tight in the stock recess when you lock up the barrel.  It gets rid of that annoying loose-rod buzz when you fire as well.  Only one of mine had this issue though.

Best of luck finding the problem or getting a replacement.  With a little trigger work, and a lot of rounds for break-in you will eventually find them to be good shooters.  Both of mine took almost 5000 rounds of fire before they really settled into consistent groups.
