Best up grades: New barrel, clamping feedneck, & stock (for those who like).
Able to use Co2 or Hpa, compact size, lots of rails for attachments.
Stock barrel, other then that nothing else.
I recently bought this marker (about 3 months ago) and it shoots great out the box. The thing I noticed first was that the stock barrel needs to be replaced with an aftermarket one. This SP1 does in fact shoot very straight and its pretty fast, even though its capped at 11bps. Another thing about it is that it weights a bit when you have it ready to play. That there is the only thing I can say thats bad about it. It makes a great starter marker for anyone thats new and wants a better marker to start with. Also more and more upgrades are coming out for it, which is great.
I'll update this review as I spend more time with marker.
I'd recommend this marker to any person thats new or even a seasoned person.
9 out of 10
