Xisico (BAM) B50 .22 PCP Rifle with Leapers 3x9x40 AO Scope – Part 1

Part 1, Part 2, Part 3

Boy, I hope MasterCard has a sense of humor… here goes: New Rifle and Scope $420, Trip to Dive shop to get what you need to fill and shoot the rifle $1600, Sending 5 pellets screaming through the same hole.. Priceless

I’m very excited to talk to you all about the BAM B50 PCP (Pre-Charged Pneumatic) air rifle. This rifle is VERY different than anything we’ve looked at so far. I want to take the time to thank for providing this sample for us to review. This is our final item from the original set of Xisico products we reviewed a while back.. The BAM B50 has a reservoir under the barrel that holds 3000psi of pressurized air. (NOT O2!) Unlike other rifles, this rifle requires a means to fill and refill the reservoir. Having never had the chance to work with a PCP air rifle, this was very exciting for me.

BAM B50 PCP Rifle. Notice the large air reservoir under the barrel.

The first thing that I learned was that the cost of the rifle and scope was just the beginning. By far the easiest way to fill these rifles is with a scuba tank. You can get a hand pump but it takes 300 to 400 strokes to fill. You can, also, get a table top high pressure compressor, but at $1800, that seems a bit much. So we are back to the scuba setup.

The gun ships with only a quick fill adapter. So the rest of the puzzle they leave up to you to figure out. I’m very fortunate to have an associate who is a Diving Instructor in South Carolina. Sergio Smith, owner of International Diving Institute, gave me an education about high pressure air and what it takes to handle it safely. The first thing I learned is that not every dive shop will be so accommodating. You may need to really plead your case to even get a tank filled, or get your dive certification. Some paint ball supply facilities may be another source to get your tanks filled, but I’m jumping ahead.

We needed to build something that would connect the tank to the rifle’s quick fill adapter. We had our first snag here. The extension that BAM supplied with the gun did not match anything Sergio had in his shop so we took that off and just used the quick fill part. Take a look at the photo below and you’ll see what I mean.

The little brass part is what we had to take off their adapter to build the fill rig
From right to left: quick fill adapter, fitting, “T” adapter, 10k PSI liquid filled gauge, fitting, high pressure hose… continued below

This is the complete rig that Sergio built for me.

The rest of my education about high pressure equipment came next. This stuff is expensive! When it comes to gear that can handle 3000 PSI, you better know what you are doing or know someone who does. You can get hurt very easily if you try and cut corners. Here is what this would have cost if I walked in his shop and needed it right then and there.

  1. Quick Fill Adapter – Included with rifle
  2. Fitting – $30
  3. Tungsten Steal “T” adapter – $30
  4. High Pressure 10k PSI Liquid Filled Gauge – $600
  5. Fitting – $30
  6. High Pressure Hose – $300
  7. Fitting – $30
  8. Pressure Release Valve – $100
  9. DIN Fill Adapter – $120
  10. GRAND TOTAL: $1240

$1240 and we haven’t even talked about a tank yet! When it comes to tanks, you have a lot of choices. Sergio let me borrow a large tank for this review. The purchase cost of the tank…. $400.


Here is the whole system ready to charge.

Now to put all of this into perspective. I took what Sergio had on hand to make this system. If he had time to place some orders, he could make a fill hose with gauge for about $200 to $250. You will still need to pick a tank which can range from $150 to $400, or more if you want a carbon fiber tank. It is feasible to get a fill hose and tank for about $350 to $400. While that seems like a lot of money to spend, you may change your mind once you read the next articles where I’ll talk about how this rifle handles and shoots. One last note, buying used scuba gear is NOT recommended. You are LITERALLY taking your life in your hands when dealing with this stuff. Saving money vs. serious injury is just NOT worth the risk. Also, once you have the basics, you’ll be able to fill all the other PCP guns you’re going to buy.. take my word for it… once you have one, you’ll be hooked! Stay Tuned!
