The print quality is excellent, and the fit is perfect. It makes the spectrum look even better and the entire blaster feels alot sturdier. Unfortunately the top rail is not picatinny at all, and is about as useless as the stock rail.
The stock muzzle is so bulky, so it could really only be used as a primary. And, with the fps, it was pretty much useless at long range. Now, it can be slung as a secondary. On a side note, installation was a bit tricky, but it worked in the end.
This was such an easy drop in kit, I was worried about tampering with the insides of a flywheel, but this replacement muzzle cut down so much bulk from the Spectrum I adore it.
I ordered both the rail and muzzle replacements from here. Installation was easy and intuitive, and the tolerances were superb and fit in the shell snugly.
Fit and work well
