Title: Are Parts Interchangeable ? Benjamin & Crosman
Post by: YankeeDude on November 21, 2011, 12:13:20 AM
I just picked up a Crosman Nitro Venom and it should arrive in 2-3 days . . . I like the way the sling mount works on the Benjamin Trail NP & Trail NP XL's. 

I am thinking about the possibility of swapping the appropriate Benjamin Parts into the Crosman to give it the same sling capability . . . Thoughts ?

As far as I can tell from Parts Lists and Schematics the Crosman Nitro Venom and the Benjamin Trail NP share the same action / engine . . . Is that true and can the parts that allow the Forward Sling Swivel on the Benjamin be swapped into the Nitro Venom ?

Also, do ALL of the parts interchange between the Benjamin Trail NP and the Benjamin Trail NP XL's, specifically the Gas Ram ? 

If the Gas Rams will interchange from the NP XL to the NP, and the NP uses the same action / engine as the Nitro Venom, a performance gain may be possible . . . Thoughts ?

Thanks !
Dave

I have heard that the XLs have a longer stroke (hence different parts) but never owned either....

I've shot a Trail NP AW and I own a Venom Dusk. From memory, the actions are externally identical, but the barrels are different since the Trail has the shrouded barrel and the Venom the plain barrel with plastic oversized muzzle blob. I believe the  Trail XL series is different internally than the AW, so expect a different spring/piston/etc there. There are parts diagrams for the AW, XL etc on the Crosman site, but the Venom is still new so there is no parts diagram yet.

Benji Trail XL is actually a magnum springer, so it has a larger piston with a longer cocking stroke, but with the Nitro Venom and Trail NP they have the same piston and compression chamber.

I'm 99.8% sure that they will transfer. They are basically the same gun, with only minor differences, none of which will matter in this case. Only 1 way to find out FOR SURE... break em down and try lol. I do know that the gas piston from the XL won't fit though...

I am mainly curious about adding a Benjamin Trail XP-style forward sling swivel to my Crosman Nitro Venom.

I have looked at the Schematics and the Parts Lists and the numbers are "similar yet different", as they change the names for each model and the numbers appear "close" but not identically numbered.  

My main concern is that the breech of the XP may be different than the NV, since the sling swivel rides between the cocking rod and the breech. I doubt they would use a thinner (weaker) part on the XP, just so a sling swivel could be mounted.

I suspect that the slot in the breech on the XP is milled wider than the one on the Nitro Venom but, of course, I don't know !

The part about using the Benjamin Trail NP XL gas ram in the Crosman Nitro Venom was only "wishful thinking"    ;-)   !

Well, according to my FedEx Tracking Number, the Nitro Venom should arrive sometime tomorrow . . .

Mod #1 will be a CDT GRT-III trigger . . . Then, I'll try to move forward with the Sling Swivel conversion, if possible .

If anyone out there who has a Benjamin NP could take a few measurements for me, it would really be a big help . . . Thanks, in advance !

Well, she arrived the day before Thanksgiving, just as we were heading out to visit friends out of town. I got home about 10:30pm on Saturday night, opened everything up to check it out and mount the scope.

The Nitro Venom has a nice balance and feel to it, but I haven't tried it out yet ( tomorrow ! ) . . . My first mod will be the CDT GRT-III trigger, which I will order next week.

Could someone out there who own a Benjamin Trail XP please measure the width of the slot in the breech for me, where the cocking rod and sling mount attaches?

I am still going to take a shot at adding the Benjamin Trail XP forward sling swivel to my Crosman Nitro Venom, as soon as I can get enough dimensional info . . . Thanks, in advance !

Are there any Benjamin Trail XP owners out there that are able to measure the width of the slot in the breech where the cocking rod and sling swivel attach ?

Thanks, in advance !

You would have to say that while my new trigger is still a few days away . . . LOL !

I am really looking forward to Charlie's trigger in my Nitro Venom. . .   Let me ask you a couple of questions?

How much lighter would you guess the trigger pull to be ?

Is the second stage of the trigger still a mile long, but only lighter ?

Thanks, in advance !

Dave

Pounds off the pull!!! That should be a selling pitch for the trigger! LOL. You can adjust the second stage to as long or as hairlike as you want but be advised that the shorter you make the second stage the more chance your safety wont work... so adjust accordingly and enjoy!

Thanks for the "heads-up" on that possible issue with the Safety. 

At what point did you notice the safety function to start becoming an issue ?

I'll definitely stay on the more conservative side . . . Thanks for your help !

Yankee dude.

I noticed when the stock was off and I was messing with the adjustment screw just to see its limits and each adjustment I'd check to see where the safelty ended up sitting at and on the safety pin there is a spring looking thing that clicks in and out of a groove when you engage the safety I adjusted mine so that it still goes in the groove when I flip the safety barely. If I confused you let me know and ill post some pics.

PICS would be GREAT !

It would really help me to be able to see exactly what you have been referring to . . .

Any progress on those pics you mentioned ?

I got the E-Mail from CDT that my GRT-III trigger has been mailed and I am watching my mailbox every day !

Thanks !

I'm looking forward to my GRT-III getting here soon and I like to "do my homework" before diving into projects.

Merry Christmas !

Codytwoeyes, yes you can put a .25 barrel on a NPXL1100.  I have just been posting this project that I accidently got myself into.  I am currently waiting on parts.   http://www.gatewaytoairguns.org/GTA/index.php/topic,22449.0.html (http://www.gatewaytoairguns.org/GTA/index.php/topic,22449.0.html)

Alright here they are!

If you look on the top of the safety there are two grooves for when you engage the safety and disengage it. I adjusted mine so when you engage it it goes right in the groove and no further. I practically have no first stage and its completely functional and safe. I also removed the stock adjustment screw and save everything that you take out you might have to put them back in case something goes wrong or you need to take advantage of your warranty. Happy shooting!

Ohhh Dave BTW can you measure your NV's breech block where the cocking linkage connects to? I know there trail's is 8mm. Thanks in advance

Mike,

As requested . . .  The width of the opening of the Crosman Nitro Venom breech block where the cocking rod attaches is .195" - .200" aka 5.08mm ( 5 mm nominal )

I am interested in modding my Nitro Venom to accept the Benjamin Trail forward sling mount . . . Pappa measured his rifle for me and the width is 8mm on the Trail NP. I am curious if the Barrel from the Trail NP will fit on the Nitro Venom. This would make the mod easier and also provide my Nitro Venom with a fully-shrouded barrel . . .Anybody know ?

Ahhhaaa that is a great idea I guess we would need more measurements and look at more schematics.  Ill be on the hunt and let you know whatever I find out

Mike,

Thank you, sir !

Maybe Crosman will eventually get the idea and make it a "factory-installed" item ? It would sure be a great upgrade to their rifles !

 I had the Crosman nitro venom .22  I did not like mine , the power felt weak to me, the rifle felt bulky and a tad heavy, I also order a stoeger x20 at the same time.
 oddly it was one oz lighter then the venom, but felt lighter and way more cool and comfortable and it had  enough power  that i was very happy with it.
 remember all new rifles have to have the barrels  cleaned inside.

the stoeger x 20 is awesome i sanded mine and re stained and refinished it and tuned it.
 btw dave the scope on the stoeger  combo pkg was stronger then the venom combo pkg and had a one peice mount too
 also installed new grt 111 trigger  aw its sweet.

 next step is i may install the first 6 parts from the Benjamin nitro trail XL hardwood .22 from the pdf schematic sheet into my stoeger, with some modification of course

 i just did that with my crosman optimist
 but used the first 5 parts from the benjamin trail hardwood .22  and man  talk about awesome.  i had to mod two things

 yes dave i was thinking of the xl gas spring myself  and i believe  they are longer, but I have to research that  to be sure.

 Maybe the  inside of the piston  where the gas springs rod seats against is shorter, so the gas spring is longer? i will order the first 6 parts from the XL and take a chance  it certainly is cheap enough

A Benjamin / Stoeger "hybrid" sounds interesting, but I don't know if that's feasible or not.

With that said, an image flashed into my head of a Nitro Venom with the barrel assembly of a STOEGER X20S SUPPRESSOR on it . . . Hmm !

FWIW - "Snail Mail" has conspired against me and has delayed the arrival of my GRT-III trigger, probably due to the high volume of Christmas mail . . . Waiting like this drives me nuts !
