@15:30 note this is for all of you 2240 custom moderz note the way the power adjuster is hollow so you can adjust the length of the hammer striker , this part was a puzzle for me from just looking at the blueprint, Thank you for this video OP , it's very helpful

[@sniperxbow60]

The second part of this video, the reassembly will be posted soon. Parts took a long time to arrive, due to the virus. Stay tuned

howdy neighbor.dont know how you remember how to put it back together.normaly when i take stuff apart it stays that way.but good stuff you have once again proved i am never to old to learn.

[@sniperxbow60]

Jeffrey, when you've had these Crosman/Benjamin guns apart as many times as I have, it's relatively easy and repetitive between similar guns. The Marauder rifle, Pistol,1720T, and 1701 Silhouette, are basically all the same, mechanically. I could've taken that entire gun apart in about 5 minutes, and back together in another 5. I slowed down a bit to explain stuff and to show the disassembly process on camera. Don't worry, I won't forget how it goes back together!!!

How about putting the pistol in a vice or padded rest while working on it? Makes it a lot easier.

[@sniperxbow60]

Barny, yes it would, but I only have a small space to work with, and have not a lot of room for that luxury. When I move, and get my workbench in order, I'll definitely have one. Happy shooting!!

I took out the spring that allows the trigger some flex when its uncocked. I am just under a pound for my trigger.

[@sniperxbow60]

Dutch, I'm just going to clean it, the trigger is pretty sweet as it stands.....the luck that I have, if I touch anything, something bad will happen to it, and I won't get it back

[@Dutch1722]

@@sniperxbow60 Not rocket science. I watched a cowboy movie while drinking some beer and fine tuning so it was as light as can be, I buffed and polished the sear surfaces to shiny, lightly coated them with moly, and tuned it in from touching the side of trigger for a discharge to a very light trigger pull for a discharge. Easy peasy to do if you have the blueprints to follow. Also the trigger stop was fun to mess with too.

[@DocMustafa]

Can’t you just adjust the hammer spring and hammer throw length from the rear of the gun through the hole below the bolt?

[@Dutch.1722]

When you take the valve off the front of the airtube, I noticed that you took off and replaced the black crosman thread tape. Is there anything special to do when you take that off? I need to replace mine with yellow gas tape to rule out a slow leak. My last effort will be to replace the gauge. I replaced all of the orings. I have re taped the gauge. Still have the leak so I wanna try changing the tape on the fill port. Is there anything special to do when doing this?

[@sniperxbow60]

Dutch, I use plain white Teflon tape, and a lot of it. Sometimes it will still leak, and might take 2-3 tries. No special trick, just a hit or miss thing. Some guys use a Permatex thread sealant instead (kind of what Crosman uses), but I find it too messy.

What would be the max distance for this air gun in sub 12ft.

[@sniperxbow60]

If kept at just under 12ftlb, I've hit targets to 100 yards with the same accuracy as a rifle with the same power, for target purposes. To dispatch small pests, up to 55 yards would be possible with proper shot placement

[@airgunsofidaho4886]

@@sniperxbow60 55 yards. That's pretty good. I been looking into the 1720t. now for a few years. Maybe in the future I'll get one. A 1720t bullpup would be nice.

[@sniperxbow60]

With some minor modifications, a 1720T with a Marauder or Challenger trigger swapped out for the original, you can put it in a Challenger stock with small modifications

[@airgunsofidaho4886]

@@sniperxbow60 i just seen a video. where someone had a 1720 on a crosman Challenger stock. I might be testing your slugs this weekend. I'll share my results with you.

[@sniperxbow60]

I've found that the 1720T shoots a variety of my slugs well, within 35 yards, which is maximum Field Target distance. I used the 15 grain flat base at the Carolina Classic in 2020, and took top spot in Limited Pistol class. I'll be competing again in 3 weeks at this year's Carolina Classic, and I'll be using the same.
