Sound Amplifier Muzzle Device for Crosman R1 / DPMS SBR Co2 Air BB Rifles

Description

While most of us are typically seeking the quietest airguns, I took a little bit of a different approach on this one.
Since the DPMS SBR and Crosman R1 type BB guns are utilized primarily for training and/or fun purposes only, I figured i'd try to make the experience a little more life-like with a sound amplifier.
No, this will NOT make your airgun sound like a real firearm
.  Not even close.  What it will do, is give you an audible increase in muzzle report with more of a "
POP
" sound.
One of the biggest cosmetic flaws of this model is that the quad rail ends with a filled in end cap that is unrealistic and ugly.  This is exposed when utilizing the stock muzzle device (left photo).  As shown below, this device was sized such that the cap is covered and gives a much more realistic appearance.
This item is 3D printed with 100% fill for maximum strength and minimal acoustic damping.
The outer surface is post processed to give a smooth, brushed finish to match the rest of the model.
This is a very time consuming effort, but who wants to put an obviously printed piece with visible layering lines on their airgun?
This is an example of what you will receive.  No airgun is included with this sale.
This item will fit both the DPMS SBR and Crosman R1.  Technically, it should fit any air gun with 14mm CCW threads, but the dimensions I designed this with were to match the DPMS SBR and Crosman R1 specifically.
