Gas efficiency. Plastic. As positioned, the tank will likely interfere with modern masks.
I got this gun not long after it came out, late in 2010. I have used it for several days and fired roughly 2000 rounds through it, a mixture of Draxxus Bronze, Draxxus Triumph, and Toxic. I've used this gun in all types of basic play, woodsball, hybrid, hyperball, speedball, and airball, and it performs well in each.
Overall I am rather pleased with it. The gun is reasonably accurate and will probably improve with good paint. The pump stroke is not as nice as a converted cocker but better than a lot of the old-style pumps. I've had absolutely no problems with mis-feeds, double feeds, or the like. The gas efficiency is not the best among pump guns, with a 11cu compressed air tank filled to exactly 3000psi, I could typically get a small hopper and a small pod, maybe 150-200 shots total.
With picadilly rails on the pump handle and along the top of the gun, it's heavily mod-able and easy to add a variety of sights, handles, etc. I found a bottomline to be a must when using it with a modern mask, otherwise it cannot be held at eye level and aimed without bumping up against the mask.
The gun is easy to maintain but two issues here. First, it didn't seem lubed enough out of the box, a nelson bolt gun should not cock when it is not gassed up but mine was doing so until I lubed it up. Also, after roughly 2000 shots, I can't help but notice that there's a bit of a nick in the ring at the back of the bolt, where it's latched onto and held back by the sear. We'll see if this becomes an issue in the future, even if it does break through the ring it looks like the bolt could be inverted and used until the other side also gives out. But it's hard to tell with only 2000 shots fired through the gun.
One other minor thing about this gun, it is quite loud.
Recommended if you are looking for an inexpensive gun for pump play that is also easily mod-able.
