Alpha Trooper Inconsistencies

I recently bought an Alpha Trooper for my brother's birthday (him agreeing with me that the AT is the best blaster in our war setting), and noticed several differences between ours.
-Range/Power: Mine has a consistent 11-12m range with good darts. However, my brother's has an inconsistent 10-15+m range. Occasionally a dart sails from one side of the house to the other.
-Accuracy: Mine has good accuracy for a CS blaster, though from what I've read, this is normal. However, my brother's has more inconsistent accuracy. I believe it's due to the power.
-Priming smoothness: My grip slides back and forth very smoothly, as if the grip has been greased. However, my bro's feels like it's scraping against something. However, given that mine is nearly a year old (got for christmas 2010) and my bro's is new, this is likely due to it being worn.

Has anyone else noticed any differences between stock AT's or is this just our pair? I know UT got a bad AT and a good AT, and posted the results/differences, but I haven't heard of it anywhere else.

Longshot LSFG Integration

I recently epoxied and blu-tacked my LSFG onto my Longshot after cutting a whole lot of stuff off. I would have used hot glue but the glue gun exploded before I could use it. :( I've got a new one, so hotglue reinforcements done.
The LSFG has had its AR's removed because it is pathetic. The Longshot is stock so far, until I get boltsled reinforcement brackets, at which point I'll mod it if I feel like it. I'm intending to do the following:
-Remove AR's
-Add NF spring
-Reinforce boltsled
-Reinforce stock (if needed)
-Reinforce LSFG integration (with hot glue)
The shotgun grip I've made is completely removable and works well, but is slightly uncomfortable (being wood).

Nerf Vortex Praxis Review

 

Goodbye AT and Furyfire as my favourites. You are now being replaced by this. Well whaddya know. AT and Furyfire are now my favs again. Now the Praxis is an equal favourite with the others. The Nerf Vortex Praxis is the second most expensive Vortex blaster so far. It is the cheapest one to use disc mags. The Praxis is supposedly the most popular of the Vortex blasters, because of all its factors put together.
