Did this video help you?

Fitness4Function: Your disassembly video was very helpful but now I'm trying to reassembly with a new flat top valve and I can't get the piston to pump in toward the valve. Taken it apart and reassembled several times with no success. Any help will be greatly appreciated. 

CARLOS RODRIGUEZ: DESMONTAGE

Syed Iftikharuddin: i have one 1322 crossma .22 ned repair iwant to sell it for 5000 only

wrockw: Thanks

Greg M: Nice vid

Charles Roberts: Hi Mike; mudduck48 here. This is a great video you have made telling how to take the "NEW" 1377 apart. Now could you please tell me how to take the "OLD" 1377 apart? How do you remove the C clip off the front pin with out scratching the barrel housing? Thank you for your time.

Jacob Magnuts: do you think the front site is a little thick? i want to get a thinner one? i may have to cot on it

fullspectrum1971: Hey Mike, I just installed a flat top valve and piston in an 10 year old Backpacker that didn't work anymore. I put in new seals and it really packs a punch now! Thanks for this video it really helped! Funny thing.... I was careful with taking the frame off so I won't lose the tiny ball for the trigger safety. But guess what it flew out. I thought I would never find the little bugger cause it's so small, but I found it. Thanks again Mike!

ArJeeVeeBee: Hi, great instructive video. How does one get the valve back in; same way it went out, or is it easier from the rear? Any tips on how to get the screw hole to line up best?

ptkenterprise70: how important is it to debur your "tube" when installing your ft piston? where did you get your ft piston? is there a place you can get all your mods?

mrSympatica: excellent video.What is the best thing to use for smoothing the inside of the tube?Is it emery cloth? or some very fine sandpaper?

miketheknife2: @mrwiggles2 I wanna see that bad boy shoot im slow but i try not to miss anything.

miketheknife2: Crosman air pistol owners forum A great forum

Marcio Maia: Great video! I live in Brazil and those crosman pistols are really expensive, reaching above US$ 400,00. So, it's imperative to keep them in good shape. And this video helped me a lot. Thanks...

miketheknife2: @fullspectrum1971 Your very welcome im glad it helped you out. Im going to install a FT setup in my M417 as soon as i get the nerve to take her apart,lots of screws and parts it should be a challange. Thanks for watching. Mike

Zhengyis: thx

miketheknife2: @MrEricdgreat No a BB is to big if you have a problem finding one send me your address and i will send you the ball. And yes keep the older classic stock. Mike

miketheknife2: Thanks i glad it helped you.

sandpiper9988: Awesome Video :O)

miketheknife2: Yes it goes back the same way it came out it cant go in from the rear. to line up the holes is easy just line up them by eye before you put it in the tube once its in put the screw for the grip frame in then you can line up the transfer port hole by tunning with a small allen key.Make sure you lube the O-Ring good before you install the valve and piston.

Angel Gtz: does any.177 cal barrel fit on the 1337

miketheknife2: @Emeraldtablet7 Cool im glad it helped.

Angel Gtz: hi mike just

fox walker: thank you . this video is a big help . the spring and ball trick is the best .YOU THE MAN !

MrBloodFF: @miketheknife2 I Heard If U Want A Longer Barrel On The 1377 , U Need To Widen The Barrel Band So The Barrel Could Go Through ? How Do U Do That ? (Please Make A Video ......…......… Thanks

G Vargas: Each time I pump this gun the air seems to come out can you tell me how I can fix this by myself please thanks

miketheknife2: @Emeraldtablet7 Thanks not a problem im glad it helped you.

CaptAmerica12: Thank You for this

Greg M: I have an older style 1377 ...the bolt does not lock well and I lose air when I fire.

morganheylvsyou: Mike, Thanks for the heads up on the CAPO forum, hey, an idea on a future video... how to change the valve spring to make the air dump better. just a thought. Thanks again, Todd

军 李: 你需要别的物品吗 我想换个1377C

miketheknife2: Thanks man.

miketheknife2: You can use a ball from one of those ball link key chains and a spring from a bic lighter.Or order from crosman.

miketheknife2: Cool glad to help

TuxedoRyder: Thanks for a great video Mkie. Was able to get my 1377 back to operation better than original after it failed to hold pressure. Just a piston cup and two O rings from crosman was all it took. Was amazed at the large burrs that required removal prior to reassembly and did not lose my springs or balls, thanks again!

miketheknife2: Your welcome !!

miketheknife2: You will cut the O-Rings and the gun will leak air if you don't debur. Look up mellon air . com.

MrEricdgreat: Great video. I lost the little ball but not the spring could I put a bb in its place or do I need to order one. Any idea what I could use instead of ordering one and have to wait? I am fixing a first generation 1377.I think I am going to retire this one a get me a new one. Thanks Eric

fjvs1960: Top notch vid. Thanks a million.

kg4eiq: I'm just getting back into air guns again. I was wanting to know how to dissemble my 1322 and 1377 and install a flat top piston and valve. Do you have any suggestions on a forum I could join to ask question to? This has been a very helpful video.

slickman911: Zzzzzz..... Hurry up dude...

miketheknife2: Thank you !

miketheknife2: @Gixxer983 No need to lube at first unless the piston o-ring is dry then just a small drop.But you should clean the barrel on any new gun.

Walter Kennedy: who does the best pay for mods around, i send them my gun and they do the mods, thanks

Craig Arndt: What perfect timing for this video, my steel breech came in the mail today from Crosman. I just finished mounting it and putting my Tru Glo red-dot. I'll let you know how well it shoots!

61pickgun: Thanks for the video...it's a great help.

miketheknife2: Your very welcome.

Steve Braddock: Great video! Do you know any valve mods for the 1377? I just picked up this gun lotta fun. I think it would be very accurate in the right hands.

dwshowman: Thanks Mike very helpful,great video

JASKIRAN115: the piece of the hammar chipped off, do you know how to get another one
