bushmaster, promaster, angel led (though not similar, electric...)
invert mini with a freak barrel
Reliable, adjustable feedneck, great regulator, awesome trigger, looks amazing, very accurate because it's stable.
It does not come with a tournament ready board...
I normally don't like to review a gun I have only shot a case through, so keep that in mind, i've only shot a case through this gun, will update if my opinion changes.
The reason why I am writing this review is because I have been so impressed with the SP1. The SP1 is rugged looking and feeling. It does not feel cheap despite being made out of composites. My experience so far with this gun has been playing renegade ball, and some round about testing, as well as breaking it down. 1st, during game play the trigger felt great, light yet snappy on the return, and It was easy to fire very quickly. I used a gravity hopper and my Reloader B. Shooting quickly with the gravity hopper wasn't a problem due to the low force bolt. Their were a few occasions where a paintball wasn't quite loaded with the gravity hopper, however it didn't result in soup in my breach, but rather a great shot just after the misfire. With the reloader B I did not have any instances where balls were double fed, so the detent system is very effective. when shooting the sp1 it is very easy to aim with your gun cocked sideways using the tactical rails and the guns body as your sites. I found this to be a very accurate and consistent method while shooting. The Sp1 shoots very consistently, I wasn't able to chrono it during renegade ball but I could see it in the resulting accuracy of the shots that followed. One of the reasons the gun is allowed to shoot accurately is because the SP1 has very little travel or "kick" during the shot. I was very impressed with this and it is one of the features that really motivated me to do this review so early in owning it. You are easily able to point, aim, and shoot, keeping your aim on the same location with almost negligible deviation, which compared to the promaster and angel I had toted in the past was amazing(not that these guns travel much, but this one almost doesn't at all). I still have to try it on Co2 however that will be coming, and another great advantage of the SP1 is that it really is Co2 capable due to the exhaust valve built into the regulator, I am excited to see the results. The gun is very quiet when shooting, making just a brief audible pop. Maintenance is a breeze, with the bolt out back feature of the sp1 It is very easy to clean and maintain, yet secure enough requiring hex wrenches(I feel this is an advantage) an it's not loosy goosey or anything either. The gun feels solid in your hands, looks very cool, woodsbally, can be adapted to speedball with a blackheart board upgrade and a double trigger upgrade(I like it just the way it is though) and it shoots phenomenally, which is something you just need to try out before you buy. Oh an adjustable feedneck out of the box too!
I would recommend testing this gun out to see if it offers what you are looking for, however I love this little thing. I like all the features which come with it, make sure you read the manual before attempting to mount the flashlight, but everything is their. Its a nice rugged, fun little gun that can meet a diverse amount of needs, whether mil sim look, or if your willing to upgrade it and want a mil sim type gun that you have the diversity of bringing on a speedball course you can purchase the subsequent upgrades and let it rip. It shoots magnificently. Try it out.
