How to tell Crosman LW Barrel?

[jwilliams]

Does anyone know a way to tell if a barrel for a Crosman pistol is a LW vs standard Crosman?

I got one with the front muzzle break/sight that is supposed to be from a 2300S.  Don't have any reason to doubt that it is a LW barrel, but can't find anything to confirm it either.  Is there anything that is unique to the LW barrel that I can look for?

The exterior differences are pretty subtle.  The finish on both is the same crummy brushed appearance, however the bevel at the muzzle is more pronounced on the Crosman barrels than the LW.  The only barrels I have handy for comparison are .177 and the Crosman bevel measures about 0.060" whereas the LW is a slight 0.020". 

A more definitive way of distinguishing them is to count the grooves.  LW barrels in both .177 and .22 have 12 grooves.  Crosman barrels in both calibers have 10.

Also the LW barrels are choked so if you push a pellet through, you'll feel a restriction for the last inch or so.  Crosman barrels aren't choked but they often come with a burr at the crown for no extra charge   So when you push a pellet through a Crosman barrel, it may snag a bit right at the muzzle.

"Crosman barrels aren't choked but they often come with a burr at the crown for no extra charge " 
Ha! Funny Jason !

All of my Crosman barrels are chocked.  Got ripped off on the burrs though.

Thanks for the info.  It's definitely a LW barrel.  Very noticeable choke.  The crown is not very deeply recessed either. 

One last question if anyone knows.  Are the barrels machined the same for the standard Crosman breeches and the breeches that come on the 1701P pistols?  I have a 1701P and was thinking about experimenting with some longer barrels for it.

Thanks.

No, not a drop in.  The TP type and location is different from a 2300S and the 1701P/1720P.   You can have it cut and machined to fit them though.

you choked the barrels yourself?

[nervoustrigger]

Oh yeah, Keith's comment reminded me that Crosman's barrels for the Marauder are choked.  That would include the P-rod.  Jonathan simply said "Crosman pistol" so he could have been referring to a P-rod.  Otherwise I am not aware of any other current production Crosman pistols that have a choked barrel unless it's a LW barrel.

Thanks.  Is the 1701P breech TP location the same as the Marauder.  Would a Maurader barrel fit in a 1701?

The Mrod barrel uses the same TP, and is close enough in location to get them to work.   The issue will be that the 1701P/1720T use a o-ring on the probe and the mrod uses one in the barrel to support mag use.   The prod bolt will not fit  a 1701P/1720T breech. 

You can easily convert your 1701P to the 12" 1720T barrel.  That should be a drop-in replacement, but only add 2" of barrel.

Thanks for the info. 

I really wish Crosman would take the 1701/1720 platform and make a small carbine out of it.  I really don't need Marauder power levels and I'm perfectly happy with a single shot.  Would love to see something like the 1720 with about an 16-18" barrel and shroud.  Make a decent shoulder stock, unlike the current one, and I'll be first in line.

I have been saying that for years, except I want it in repeater.   I have built some long tube ones, but not that economical.  Maybe crosman will surprise us at the 2018 Vegas gun show.

No identifying marks on the LW barrels, so externally (if the same length as a standard Crosman rube) there is nothing you can quickly check.  Likely could tell from a comparison look down the barrel, but unless you had a standard Crosman made barrel AND an LW barrel, though won't be a "carp load" of help.

[nervoustrigger]

Um, again...

LW barrels in both .177 and .22 have 12 grooves.  Crosman barrels in both calibers have 10.

[Ribbonstone]

Ok...a guy with ne barrel (nothing for comparision) likely could calm down...get an accurate reading of lands and gooves...probably get stuck at "11"...then recount.

But would it really hurt Cosman to stamp a little "LW"..and "X"...or even make then 2/10ths an inche shorter or longer taha a standard Crosman barrel?

[nervoustrigger]

Haha, good point   A little identifying mark would be nice and would be a mark of prestige to encourage people to upgrade.

Regarding counting the grooves, yeah I would struggle with the naked eye.  I grab a 3x or 5x jeweler's loupe and then make a little pencil mark on the muzzle to indicate the starting point.  Then just rotate and count until I get back to the pencil mark.

[FuzzyGrub]

I thought you said crosman marks their barrels with an identifying burr? 

FWIW: I don't remember seeing any identifying marks on LW blanks.   If there was one, it is gone by time you cut and machine it to fit your gun.

Initially I thought counting grooves would be the easy way.  Harder to do than you would think.  Didn't try to mark a point on the barrel.  The very pronounced choke and narrow crown bevel were enough to convince me.

LoL!!!  N.T, now That was Funny!

Trigger said that all his Crosman bbl.'s are chocked. He never said they are choked. LOL!!!  He must be putting chock's under all of them to keep them from rolling off the bench.
