Default Crosman C9A

Hello Air Gun shooters & Merry Christmas. I picked up a an older .20 Air rifle, and I'm not overly familiar with them. It was in a local thrift store with a price tag of $49.00! As I was looking it over, a couple of other male customers wandered over to me, and expressed interest if I wasn't going to buy it. I snatched it immediately without even a good inspection. It seems solid. I believe it's a discontinued Benjamin-Sheridan. It was a bit stiff and dry, and the bolt didn't want to move at all. I applied some Pellgun-oil to the pump linkage and bolt. It holds air, and seems to shoot hard. (I don't have any .20 pellets, so that's why I wrote that "seems" to shoot hard.) The original rear sight is still attached, and judging by the various screws, it appears that it has never been taken apart or "opened up". There's no evidence of a scope having been mounted. Basically, it seems solid with just a bit of honest wear. Naturally, I was unable to locate .20 caliber pellets at WalMart or Big-5 (but I checked anyway).

So here are my questions for anyone knowledgeable about the Benjamin-Sheridan rifles. First, the pump handle seems to be a little bit out of alignment with the stock. Is there a simple fix for this? Second, the wood stock looks very different when compared to my Benjamin 392. On the other hand, it appears much lighter compared to my other Walnut stocked guns. Is this a Walnut stock? Lastly, what part of the serial number will tell me the year of manufacture? Thanks in advance for any information.
UPDATE: There's actually a bit of black paint still inside the last half-inch end of the barrel. I think I'll remove that now.

Just looking at pic 1 I can tell its 90s-early 2000s. There should be an etched serial # the first 3 digits will be year month.
Far as pellets go I always order online as big-5 is way over priced. The big5 in my area recently started stocking the .20 Benji cylindrical pellets. Order from a site called Pyramyd air. They do the buy 3 get 4th tin free. The Benji and JSB are the way to go.
That's a walnut stock. Since it's a Crosman made Blue Streak you can see the similar design that your 392 has. So you got a walnut before they went to the cheap hardwood.
The pump arm could be due to a previous owner over pumping it. Which requires more effort and causes improper pumping technique.

Hey Rob,
Thanks for the response and information. Yes, I had previously read that the first digits of the serial number were the month & year of manufacture, and it made sense when I looked at my 392, which reads: 013, which I believe means my 392 was made in the year 2013; that's also when I purchased it. This C9A serial number starts with: 601; which I suspect means June of 2001. I pulled the bolt out last night, and cleaned it, pulled the stock & cleaned it, and applied some paste wax and hand buffed it. It looks much better now. I took a closer look at the pump handle alignment issue. It appears that (perhaps) the previous owner was pumping it, and somehow allowed it to twist. I try to avoid doing stupid things with my gear, but I put the rifle in a padded vise, and used a large screw driver to gently untwist the pump arm linkage. It looks correct now, but who knows. I'm going to install my Williams peep, and shoot it a bit for groups. Thanks again for the information.

Nice work brother! If the stock is still off a little and it bothers you. It did for me on many of occasions. Get yourself some of the small felt stick on dots. Add them to the inside of the forearm. Obviously, add them to the side that will adjust the forearm in the direction you want. Now in the closed position it will make the arm sit straight with the butt end. This will also quiet down the rifle during pumping.

Default C9A update

Hey Rob,
Thanks for the note. I borrowed the Williams Peep sight from my 392, and managed to find a tin of Benjamin .20. The rifle shoots one hole cloverleaf groups at 15 yards, and just a bit bigger at 20 yards. When I move it to 25 yards, the groups open to about an inch. To be fair, I think it's my old eyes are unable to focus on the front sight as well. Might have been the sun at that time of day.

The pump arm lines up pretty well now, but my OCD mind won't let stuff go. Anyway, I took the top end off (put some oil on the pins, drove out the two pins, and then the little pin inside. I removed the little wheel, and I can clearly see where one of the twin bars is slightly bent. I put it in a padded vise & attempted to tweak it. Honestly, it looks the same now as it did before I attempted this fix. By the way, I've seen several of your posts on the GTA, so I know you are familiar with what I'm talking about (even if I don't use the correct part names).

I might just keep it and shoot it as is. But, there's a part of me that keeps looking at the Mac-1 Solid Steel (Billet)Pump Lever. On the surface, it looks like a simple part exchange, but I know I'll have to drill holes in the wood pump handle in order to remove the two pins. I'd hate to mess up this C9A. I might just send it to Mac-1 for the complete package.

I've always wanted a steroid 392, but my current production 392 was a refurb and accuracy isn't great. The wood on the 392 looks and feels cheap. I also have a Lundy Integra Base that I also experimented with, but it puts the scope up pretty high, presenting a poor check weld. Also had to bend the bolt handle a bit to clear the scope, and then pumping is a problem with the scope in the way. Basically, my 2013 Benjamin 392 isn't worth the cost of the Steroid. It's too bad Crosman doesn't make a higher grade 392. Anyway, thanks again for the help. I'll look for the felt stick on dots.

There are 2 parts that Tim has that I absolutely love. His front end plug and the steroid lever. Both are rock solid, should I say steel solid. I've managed to get power up to 18.39 FPE on the cartridge 392 and C9A with only 8 pumps. So I don't need the steroid lever as I'm not over pumping like his steroid rifles need (14pumps)to get max power. Regardless, his lever is very nice!! It really adds heft to the rifle. For my keeper rifles I'll get his steroid plug. It's a well made solid piece.
So here are some pics of the lever. I lined up rifles that you have so you can get an idea of what you need to do. All the holes are at the same distance apart regardless of model. The left rifle is a 392pa. The middle is a 392P with the steroid lever. Right is a C9A.

Notice the middle lever is solid as oppose to the other being hollow.

Steroid lever

Hi Rob,
Thanks for the follow up. I sent you a PM. Thanks for the photos. I've never seen what the billet linkage looks like installed. I was considering buying the Billet parts, and having a go at it. Given the cost of the parts, I might as well throw another $75 at it for the power mods, and just have Tim/Mac-1 do it all. I sent him an email a few days ago (no response; I'm sure he is busy). I'll call him in the morning for shipping instructions. Thanks again.
