"Ziabeam"My .25 came equipped with the fixed FX shroud.
At "max" power setting (factory settings) it is
quieter than popping the top on a canned soda, and that is with no baffles **(baffles not included) So quiet in fact that the absence of baffles instantly became a non-issue for my needs... and my neighbors are close on 3 sides
End cap inner cone is machined a little rough, but the fit and finish of each section's threads is very smooth and precise, allowing near seamless transition between segments and fairly close tolerance exit @ about .290"
There are 4 identical middle sections plus a distinct front and back. The rifle cutout in the later "long" hard-case requires at least one LDC section be removed to fit.
** These late style segmented LDC's appear to be designed to readily accept a baffle(s) with .125" thick edges.
