We are talking serious fun here!!
For those unfamiliar with the model this is one of Crosman’s most successful pneumatic air rifles and their site boasts that well over 12 million of them have now been sold.
The rifle is charged by pulling down the front fore end and ‘pumping’ it from 1-10 times (cheaper than going to the gym and far more fun...). Dennis Hiller’s Airgun Collectors book indicates that 3 pumps can give around 428fps, 6 pumps 567fps and 10 pumps 637fps in .177 pellet.
The rifle takes either .177 pellets as a single shot, or up to 100 BB’s can be loaded into the reservoir within the stock.
.177 pellets are loaded directly into the breach by pulling back the cocking lever on the right hand side and seating the pellet in the channel. When the cocking lever is returned the pellet is pushed forwards by a rod.
BB’s can be poured into the reservoir via an aperture in the butt of the pistol grip. The black cover on this can be slid backwards to expose the hole. With the BB’s in the reservoir the repeater tube on the left hand side can be cocked by pulling back the lever and locating it to compress the spring. If you then tip the gun forwards and rotate it a stream of BB’s will roll forward into the tube.
We never really used this with BB’s due to the ricochet factor. We just ploughed Marksman and Wasps through them at an array of paper targets and spinners at the bottom of the garden and Dad fitted a basic 4x20 scope to one and used it as an excellent ratter when some moved into the garden.
These have both been used and are working fine with pellets; I haven’t tried them with BB’s simply because we don’t have any. If you want to try either of them out before buying drop me an email and I’m sure we can sort something out…
I have TWO of these to try and rehome, one is slightly older with a different rear sight. There’s plenty of pictures of each so if you’re interested have a good look and contact me with any questions.
Both rifles;

Rifle 1 ; the older model version.
The stock and fore end are wood effect plastic and it has a rifled steel barrel.
Condition is good; no repairs or damage, all plastic is intact and it has the original Crosman marked butt plate. The rear sight blade is a fixed metal one with slot in the top. There is a push-safety button to the trigger housing which works fine. The barrel has lost a lot of the blueing as can be seen and there are some marks to the japanned finish of the action. Big Crosman logo to the left hand side with the model details.

If you know how to date these then the serial number is 678015996: looks like June 1978.
I’m asking £49 collected or posted at cost: just give me time to round up a suitable box! Having just parcelled up the one below I know it'll weigh in at a shade under 3kg so for the UK the postal options would be;
1st class recorded delivery (insured to £39) £9
ParcelForce 48 (insured to £150) £13
Special delivery £21.65
* SOLD to White Ferret pending usual.
Rifle 2 ; the newer model version.
Again, the stock and fore end are wood effect plastic and it has a rifled steel barrel.
Condition is good; no repairs or damage, all plastic is intact and it has the original Crosman marked butt plate. The rear sight blade is an adjustable plastic one that moves up and down a ramp. There is a push-safety button to the trigger housing which works fine. Very few surface marks to either barrel or action; essentially very tidy. Crosman name to the left hand side of the barrel and model details to the right.
Serial number is 377461710, so March 1977
