Crosman 1377 Piston And Valve Mods




What do you think about this video?

fsdarrell: You mentioned slightly enlarging the valve port; did you also enlarge the transfer port bushing? I believe the current port bushing size is 9/64 inch in US 1377 and 1322 models.

AmericaThe Beautiful! ___: Thanks, I just bought a 1322 and liked it, and a 2400KT is on the way... now I understand how this thing works.....

FJvoodoo: I duracoated mine after 8 years of service. Looks bitchen, was easy to do, now don't have to worry about rust.

Georgii Agapov: ватафак?

Hugh Jhaz: hi .... the model 1377 I have has a sliding breach cover and a plunger type thing you pull back to load spring.. is this a mod or just a variation... would love to know about it...
thanks..

those gains aint loyal bra: for those who live in america your so Lucky. The crosman cost like 50 bucks right !? crosman is almost giving them away for free. Here in holland they cost twice as much and the extra parts like steel breech kit with bolt etc cost like 80,- euro's. Man i want one so bad and fully upgrade it but the gun alone is 100,- euro including shipping. And then i hear you guys pay less then 40,- euro. freaks up my high all the time. Great video btw

N. C.: Hey, just got me a 1322. I remember my grandpa had one of these when I was kid, this was back in the early 70's. He used to sit in his chair and shoot birds and gophers, lol.
Thanks for your video, it really gave me a good understanding when I do my mods.

kevin singh: what mods would i need to do to increase power/fps and where exactly can i get these parts needed?

j Kara: well explained, quietly.

TheVabene73: do you think by trimming off the cone of the original valve will increase velocity to my 1377

David Matthew Summers: I've killed squirrels and 🐦🐇🐀 with mine. Since its a straight shooter I go for head shots. I hit a 🐇 and he ran off. It took 30 minutes to track him Dow. He was done.

Myles Nicholas: So it's 10 pumps for every single shot, that put me off.

Glenn Hanson: Man. I am resealing mine for the first time ever. I can see why that o ring and cup have to be in excellent condition. It's hard to believe that that pump system can overcome the pressure exerted from that spring on the inside!

frederickwentz: I pop squirrels out of trees, and killed a few rabbets with mine. Its the loading that gets me, But at 20 feet it puts a hole into the side of a old dryer. Now I may go to a flat top.

fatbarry barry: for this to be on sale in the uk it had to be under 6ftlb im sure air comes back out the valve after 10 or so pumps, seal up the overflow if its not tamper proof,  i had a rifle like this called a sharpy ace you could pump it up til the pin in the roostering arm snapped 20 pumps would be over 35ftlbs

Kaka Brar: what good is that gun for ? i mean we cannot hunt with crosman 1377. 600 fps is still little less for small game

Joshua Purple: nice detailed walk through of the pumping mechinisms of the 1322/1377...I have actually been looking for somthing like this for awhile now...I have my new alchemy airwerks power RP pumper valve coming today and wasen't sure what I needed to do to take the valve off/apart....still looks like its gona be a pain lol

Mekratrig: Nice, clear, explanation and reason for doing the mod. Thumbs up.

quicksilver40: Thanks for the vid on the flat top parts I've been looking to add.

toneknob: another plus for using a multi pump pneumatic is that you can get full power all year round, unlike CO2..

Schools: Learn how to get phlebotomy training in California! The job pays decent money for the amount of schools needed to graduate.
