A non-upgraded spring sniper? You'd be better off throwing BBs at people. I had a similar issue so I bought a couple extra AEGs, they are a much better loaner and backup. I've a had a fully upgraded TM L96, total cost would've put me at over $1,400 and it still wasn't precision enough to be worth my time. They are only fun if they are crack accurate and you want to be in the top 1% on the field for distance.
If you're set on buying a cheap one, then get one that is 100% TM VSR compatible. At least later on you can tinker with it and make it viable.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
