Crosman 2100B

I now have a Crosman 2100B. Yesterday was abit cold out at 6°F and little to no wind. From having used 13xx" i learned that under 30°F there would be a loss in pump pressure along with lower velocity for the given # of pumps.
First off i started by adding a drop of Pellgun oil on the pumpcup. Next was to tighten all screws. There are a couple scratches on the barrel shroud near the muzzle but nothing bad.
I shot around 15 times and adjusted the elevation on the open sights to hit near near POA at 20 yards. The first shots hit low and left using CPUM 10.5gr and 8 pumps. The Front sight is abit wide with a green fiber insert. Nice and bright but abit wide. The elevation is adjusted using a stepramp, windage is adjustable by loosening two screws. I didnt adjust the windage as this run was mainly a function test along with initial inspection and firsthand insight and handling, also that 6°F is Cold. Today is 2°F with 20mph wind, no go on shooting for today too cold and windy.
The reciever is metal, not sure what kind but it is stronger than plastic. Pumping was not heavy or loud. Trigger has some travel, it went off when i wanted... i do need to get a better feel of the trigger but seems good.
The length and weight feels nice, heavier than a DP880. I noticed the stock to reciever connection has some wiggle. Also the barrel shroud to reciever also has some room to play,, rattles when i shake the shroud.
At a later time i will be taking this Air rifle apart but just not yet. I have a BR LDC for the 2100 that i will be installing, i would also like to tape mod the strawbarrel and findout how i can rid the stock and shroud of wiggleroom or "play". The Crown appears straight and even. Good. At a later time i will be adding a scope possibly a Svitvu 3-9x32mm HMD. I have 3 of these that i have manually adjust the parallax to airgun ranges.
At a later time when temperatures are warm enough i will be testing pellets on cans and through the Chrono.
I know this is abunch to write/ read after only 15 shots. Thankyou for reading

Is that a new or used 2100B ??
Stock wiggle typically indicates fractures on the "clevis" ears inside the receiver.
Applying a couple wraps of electrical tape around the stock where it mates with the receiver will generally tighten things up a bit.
If you have never been inside a 2100 type rifle there are a few fiddly little parts to watch, and alignment
of barrel and air tube in the receiver is important for ease of assembly.
Good luck!

Ronno6,
This was bought new from Mart op de Wal. They had a good low shipping cost of 12 dollars, so i paid around $75.
Thankyou for the info. I would like to get rid of as much slop movement as i can in the stock and on the barrel shroud. At a later time i will be taking this 2100B apart to see what i can do to improve the Air rifle. Also, thankyou for your posts that involve the 2100, Ronno6
When temperatures rise above 30°F i will get on sighting in and testing pellets. I will update when the time comes.

I can always appreciate your write ups about your airgun adventures. They are inspiring.
Plus the use of Dutch language makes me smile as it is my mother tongue.
Anyway, always in de back of my mind to buy a pumper rifle as well, but can't decide on the 2100, 880 or the NXG LOL (but that is a topic on its own).

triggerfest,
Echt heel erg bedankt.
Think i spelled that right, thankyou very much triggerfest. A few other phrases i have learned years ago; " Ikbiendekoning, ikbien nummer einz, zu hart du weist lechaben truthahn." Hehe, note i am not calling you an intending turkey.. ok buddy.
Ok,, op de Pumpers, well i dont have much shots through this 2100B, but i can say it might need some work to be goood. The first are the stock and barrel shroud wiggle. Got to rid the air rifle of playroom. DP880 is a good easy to work on pumper easily modified. Having filled the limiter slot with cold weld then shimming the Piston Orings i have gotten gains of around +30 FPS at 10 pumps. You are in NZ? So are you able to find a Winchester 1977, or a Crosman 362?? I like these ones mentioned DP880, Win1977 and C362. Dont have any insight on a NXG, just know it has automatic safety that engages once the bolt is cycled. Crosman have thier advantage in being able to hold air before the bolt is cycled. And DP and Win have thier advantage in being easy to work on and resistance to cold temperatures.
In a couple days the weather forecast shows a few days of above 30°F, so if the wind will allow i might be able to get more shots though this 2100B and get some testing done .
Thankyou for your reply triggerfest.

Cheers, I am in the Netherlands and we don't have the Win1977, but we do have the C362. But I am more like a .177 shooter when it comes down to a sub 15fpe airgun. I've heard there is a C367 on the horizon as well ? that might be a great candidate for me.
Cheers.

Ronno6,
Today i shot around 10 times at 15 yards and 6 pumps with DFN 7.6gr. Some wind so not exactly a accuracy test day. 10 shots in about an inch at 15 yards with 10+ mph winds.
So i got to taking aprt the 2100B...
When you said there would be a few fiddly parts,, you forgot to underline highlight and exclamation point each side to the word Fiddly. Wow i opened the reciever and the whole thing came apart,, ooh man I got some work todo. XD
I installed the BRLDC and am in process of thinking up how to tapemodding the barrel to shroud. Seems a round or two of electrictape will fit where the barrel inserts into the frontsight shroud. Ill see about wrapping most of the barrel and possibly shimming the shroud-reciever and the stock- reciever. Ill see what else i can get done and get this thing back together..

I tried shimming the muzzle end of the barrel with electric tape, no fit. Where Vinyl electric tape doesnt fit threadtape will fit. 4 rounds x2 of threadtape where the barrel meets the frontsight. Next 1.5" from the muzzle 8 rounds of gorilla tape + 1 round of electrictape perfect fit i also added more to make 3 of the tape shims to hold the barrel firmly in the shroud. I can hold the shroud and barrel upside down and get no rattle. I also added 1 round of electric tape on the stock inside where it mates w the reciever.
Now i need to figure out how to put the reciever and trigger parts together....
Ill add more to this thread after completing more. ExcellentWork StayAlert

Nice looking work. Ron's O-ring sealed brass bolt probe will get you another 20-30 fpe. Worth it.

Ok. I added another shroud shim for a total of 4 tape shims on the barrel. After having taken apart and reassembled, took me awhile to get it back together. But it seems i am getting retained air at 6 pumps. No retained air at 5 pumps. I did take it apart again and made sure the hammerspring plug was aligned. I also oiled the hammer too. But idk what but for now it is retaining air. I might have to add #6 shims to the hammer,. Idk why it is reataining air. I Wonder if im losing air at the TP-Valve connection.,,
I did rid the 2100B of wiggle rattle playroom. Feels solid and abit heavier w all the rounds of tape.

I took apart the 2100B again to get some work done. I added 3 layers of thread tape to the bolt and inserted into the breech to ensure there is a good fit. I then added a layer of superglue to the threadtape to hold it in place.
I also added threadtape to the TransferPort to make a better fit asit is there is alot of wiggleroom between the TP and the Valve exhaust.
It seems that my Pin return spring in the Valve is tooo strong for the light hammer and the spring. I used a screwdriver to push and hold the hammer in to try and loosen up the spring. Either i keep shooting and possibly slowly the valve spring will work itself to where it no longer holds air. Or.... i would have to take the valve out take apart and clip some of the valve spring- something i dont want to do..
I will add more to this thread after completing more if anything..

I have added 2 of #6 lock washers to the hammer and i was still getting retained air at 6pumps and no retained air at 5 pumps.. After a number of shots i shot a few 10 pump shots with a little air retained but continued to retain air at anything past 6 pumps.
So im thinking if i keep the valve spring compressed and allow the air rifle to cool to the 1°F this should help the spring hold a new set and weaken the valve spring, i hope.
I took apart the air rifle and inserted a screw driver into the hammer to compress the valve spring. I used gorilla tape to hold the screwdriver inplace. I am Going to leave this outside for 17+/-hours and see if this will work on weakening the oversprung spring. The weather is suppose to get down to - 9 tonight brrr..

I reassembled the 2100B yesterday. The valve spring is alot easier to compress, before it took alot of weight to get the hammer to move.
10 pumps indoors then went outside to test. There was a little retained air at 10 pumps. I think when the airgun is pumped the valve is filled with outside cold 0°F air. I am very sure this has an effect on the valve spring causing it to stiffen and causing the retained air. I have been shooting this 2100B in temps i would not expose to any of my 13xx"s.
So once the weather has warmed abit i will get more shots through. If i feel like it i might long compress the spring in the cold again using the screwdriver+tape. Note- the threadtape on the bolt did not last.
Thankyou for reading.
