I have check my M4 and my friend's m4 (in his m4 the hop up works good) I test the my barrel with hop upl in his upper receiver and his barrel with hop up in my upper receiver. I see thats not a problem with this part which push the hop up to hopping. The problem is in my hop up gum. Now i looking what is wrong, becase for first looking, it looks good but not "hopping" good

@weekenny First of things that i think about - was about dirty hop up so i clean it but it doesnt help @t_hum 1. yes 2. Tightened down 3. yes I will try to put more tape or maybe make something to make hop more out in the barrel.

I cant understand why my hop up doesnt work because when i use tape, the hop up stand out more in the barrel but the bb's are hopping much worst them the hop up in my friend's M4 KJW. With tape is a little better then i have stock, but it still bad (first i have 25m on 0.25, now i have something about 30-35m on 0.25 and my friend in stock has about 50m ... )

Hello I have a big problem with my hop up ... ;/ The bb's arent go up (0.25) I saw the little help on page 138 but it doesnt help ... I wrap aroung a lot of tape on hop up arm but it helps only a little. The M4 of my friend who bought the gun in order with me - shoot very well and dont have any problem with hopping the bb's wtf? PS. Sorry for my english. I'm Polish
