just joined and cheap air guns

All the airguns I have are cheap. Or, at least they started out cheap. I've modded them all to some extent. Some mods are fairly inexpensive ( or almost free). Other mods are more costly.

If I added up all the mods to what I've done to a pair of Crosman 1377 / 1322's: I'd say I probably have around $500 invested in my homemade, Crosman 2289 Backpacker and the same amount invested in my homemade, Crosman 1389. Both of those are superlative airguns, so it was and is worth it.

I got my Crosman NP2, .22 Summit Ranger on sale for $99 (it's my understanding Midway had them on sale for $67 6 month's before I got mine). After adding a M*Carbo NP2 trigger kit ($15), a Tasco 2.5-10X42mmAO scope, an LDC and a sling, the total cost is now around $150.

That NP2 SR can now compete w/ some of the best springers around though. 
 
thats great i am going to have to learn about some of these mods

For the 3 airguns you mentioned in the OP: 'crossman 760 crossman 1077 daisy 880' - there are a plethora of modding vids on you tube. I hope that 760 you got isn't the new one that has the smooth bore barrel. You're limited to about 10 yards w/ that one. Unless you swap that barrel w/ a rifled barrel.

I have a thread on the Winchester 1977XS and the Daisy 880 that has quite a few mods.

they crothhe ssmans i got are smooth bbl but i have them dialed in for 20 yds both are very consistent the 880 is more accurate even with open sights hits harder too but for 50 60 dol guns i am pleased wih all three cant understand all the neg reviews none of mine have broke in half or anything your not buying a 300 to 1000 dol gun i do expect them to work they do that and they are what they are but i will be checking out some mods and higher priced models
