    OK I have the benjiman trail np xl 1100 with the lousy trigger. I decided on the bearing fix and really have a sweet trigger pull now. Problem is in my trying different bearings, 5x8x2.5mm, 5x9x3mm and 5x10x3mm I tried the 10 mm first, “WRONG” After installing I cocked the gun and did not hold the barrel, SLAM barrel slammed closed !! Well obviously that was the wrong one I needed a smaller bearing. I installed the 5x9x3mm bearing and boy O boy what a sweet trigger. .A couple of days later I took my gun with the sweet trigger pull out to plink a little. DADGUM shot 2 feet high and 6″ or so to the right. Seems the slamming had done some damage. I contacted one of the better airgun smiths and was told three methiods for repair. #! tape the lower scope ring shimming the scope up. #2 bend the barrel and #3 replace the barrel. NOW has anyone here ever replaced the barrel on a Benjiman trail np xl ??? If so how is it done ?? What do I need to watch for the do’s and don’ts. Any help will be appreciated.
    Ron tha dumbass

    How many yards were you shooting at when it was 2 feet high on POI?

    I would have to say I doubt you hurt the barrel on that when it happened. DO NOT try and bend the barrel!

    For scope shims I use soda/beer can material. When I had extreme right or left issues on scopes I had success by switching the scope mounts either front/back or just flipped them depending on if you use a scope stop. For up/down adjustments I use a shim where needed.

    “lacey1948”10 yds

    
Try and flip flop the scope mounts, see where you at then on your scope adjustments. From there you will know what mount needs shimmed.

    I usually use a double layer of soda can on rear mount when using crosman mounts. That keeps barrel droop in check on Crosman stuff. I prefer to use Hammers 4 bolt dovetail scope mounts nowdays if I am not mounting to a weaver rail.

    I have a high and a low mount Hammers scope mount that came with my scopes.

    I put another scope on it with the same result. I did however use the same mounts. Tomorrow I’ll swap the mounts around and I got PLENTY of empty beer cans to make shims. Thanks to all

    I would replace the barrel if it was off by that much.  I would remove it, take the sight of the front and roll it and confirm it has a bend.  A damaged pivot is also a possibility.  If your pivot on the frame of the gun is bad, you are pretty much burned.  If the barrel has an obvious bend when it is rolled, replace the barrel.  Two feet of error at 30 feet is a massive bend.

    I did a similar thing with mine it had a visable upward bend , when you remove the barrel shroud the barrel its self is pencil thin imo these guns are junk

    You can bend the barrel back down. It is not a big deal. I have done it with great success. Use a wood vice to protect the barrel and bend it a little at a time.  If the rifle was sighted in before just keep test firing it till the pellet impacts close to where it was before. Some barrels bend easier than others. Tom Gaylord show one way here to get it done.

    remove 3 stock bolts, 2 up front, 1 at trigger.

    remove barrel pivot bolt, and cocking linkage clip.  Thats it, I still woudnt rule out scope mounts being off first. Swap the mounts front to back AND rotate them (bolts on opposite sides of current location) first.

    Lots of Crosman dislike/hate here……Dont get yourself down about that. Thats one of the reasons I dont frequent this forum as much as I used to.That and I have kinda moved on to other aspects of outdoors activities. I have owned 3 Crosmans now since I started last year and they are just fine for 25-40 yard pesting with trigger work and upgraded barrel pivot washers. Now, they will not stack pellets in same hole at 50 yards like the FWB or other match grade rifles. If you are ok with nickel/quarter size groups at 25-50 yards then you will not be disappointed. I thoroughly enjoy my Crosmans, and have another one on its way as we speak.

    That being said, my $89 Walmart Ruger Blackhawk Elite was simply amazing and would stack pellets in same hole at 25 yards. If you dont like the Benji, take it back to Walmart as defective (i think they will let ya return it) and get the Ruger. My nitro venom 22 had teething problems, until I made some brass pivot washers, upgraded scope and mounts, and did the trigger mod. Now its my go to for pesting.

    Oh yeah, and……my Nitro venom Dusk 22 was off so far when I got it I hit the wrong target paper on a 2 paper target hanger at 20 yards!

    Google is your friend-here’s a video in which the barrel of a Crosman Phantom is removed. It should be very similar to your Benjamin as far as the way the barrel is attached.

    Pay careful attention and take pics of how things go together so reassembly goes smoothly. Lube the fork, the breech and the washers lightly with Moly lube when you reassemble. If the breech washers are plastic, see if you can find brass replacements the same size at a good hardware store. You may have to do some filing to make them beveled.
    Good luck!

    Do yourself a favor and buy a Hammers 3x9x32 AO scope. and a set of quality weaver scope mounts. I cant recall which set I chose for mine. They were Lows, I think I would prefer medium or highs just because I am a bigger guy, but the lows kept the scope where it should be and inline to the bore.

    Bend the barrel back. You’ve got nothing to lose at this point.

    HERE is an interesting read on bent barrels. BTW, the gun below shoots straight. Go figure.
