Title: MROD GEN2 DISASSEMBLY/REASSEMBLY JSAR ALUMINUM AIR CYLINDER
Post by: Hajimoto on February 20, 2018, 12:42:01 AM

Well, New Years Resolutions are always made to lose weight and here is my MROD GEN2 .22 keeping its promise to lose a few pounds. I upgrade the heavy steel air tube with a Jefferson State Aluminum Cylinder and man does it lighten up the rifle!


The rifle will be torn down and reassembled with a JSAR Aluminum Air Cylinder, JSAR SS Balanced Valve, JSAR Super Hammer, JSAR TSS GEN2 and Huma regulator. The rifle will weigh almost 2 pounds less when this is all said and done. The MROD had most of these modifications already installed but I never documented the installation but have been promising you guys that I would, well here it is!

This is one of the best R&R (Remove and Replace) tutorials I've ever seen, including many professionally produced vids I've watched during my 30+ year career in the aerospace industry.

Well done Haji!  We now have an updated Gen II R&R video we can refer the newbs to when needed.  We use to have to refer them to the Gen I videos.

One of the most meticulous dis-assembly/assembly videos I have ever seen.  I like how you repeatedly checked for air pressure, and de-gassed multiple times.  Perfect training for the newbie. 

The JSA air tube, without the gauge hole, will need a vent hole since you are using a regulator.  That doesn't take anything away from the video, but will need to be done to prevent regulator creep.


UPDATE: It was covered in the video just past where I stopped.   :-[

Well done Haj..
The light tube is on my to do list. Your video is done in a way that I won't need to refer back to it when I install mine. It's not all jumbled up with useless info so key steps can be remembered and focused on.
Thank you and JSAR.

Thank you for the kind words, I really appreciate it. As for the Huma regulator vent hole, you may have missed it but please refer to the video at 29:26  ;)

I only had time to skip around it, but it looks very good. I did skip towards the end and noticed the warning about dry firing a SS valve, but I believe that the wording will easily mislead a new user to actually dry fire it. You say to not dry fire it without pressure, but a new user may not equate that to the backpressure from a loaded pellet. They may think that they are fine because there is pressure in the tank, and proceed to dry fire it. I would suggest a more clear text there.

If a new user understands it as you have written it, they would be correct, you NEVER want to have the hammer slam into the valve without pressure in the cylinder.

I understood that the SS should not be dry fired period, meaning do not fire it without a pellet loaded. However, that is exactly what you do in the video, which is wrong for the SS. I hope that Travis will comment. If I am wrong, then great, I learned something.

As I have understood it: Do NOT fire the SS valve without a pellet loaded.
As you described it: Do NOT fire the SS valve without pressure in the tank.

Ah,  ::)  I stopped this morning right after the huma install, before heading out to work.   I had noticed earlier in the video, you mentioned no hole in the tube, and then starting installing.

 The term dry fire can mean two different things 1. to fire with no pellet in the barrel 2. to fire with no air in the cylinder. Im referring to the second. Do Not dry fire the valve with no pressure in the cylinder but its fine to fire with no pellet as long as there is pressure in the cylinder.

Wow. Thanks for this. So the video is correct and my understanding of the SS was wrong. You guys might want to clarify this on your website as well. I never did either one with my SS, but I fully thought you were warning against the 1st.

I was thinking about dojjng all these on my mrod with the exception of using the Huma regs with built in gauge hole. A lot of money though and want to be confident it is worthwhile.

Correct, it doe snot need to be put back in but in this video I tried to address all configurations. You may have noticed that I kept saying if you are not putting in a regulator you will be reinstalling your pressure gauge block which would go hand and with the depinger being installed.
When the video was complete I took all back apart and only had the items that were appropriate in my build. Good question though, hopefully my response answers it.

I just got mine last week and must say it is a great product.The finish actually matches the shroud better than my old one and everything fit perfectly.The install went very good maybe a couple hours and the weight of the rifle now is so much better. I really learn a lot from watching these instructional videos. Thanks

Hey Haj..
Basically posting to bring the thread back to the top. I'm installing my JSAR tube w/gauge hole this morning and I want to refer to your video as I go if I need to. I've watched the video a couple times and it really does give me confidence that the install will go smoothly.
Thanks again for making this video. It's by far one of the best made tutorial videos I've watched for any air gun upgrade.

My understanding is nothing has changed that would prevent you from doing exactly what is captured in the vid.
