ATI Nova Liberty, Freedom, and Seneca Aspen Monocore XL Baffle Stack
Increase the sound suppression of your shroud with this monocore. This is a two part system that replaces both barrel bushings. It pushes the shroud an additional 40mm past the barrel, giving room for better sound suppression! It also features vent holes so you don't have to drill holes in your shroud. It is optimized for .177 and .22 caliber. This system is for more advanced airgun tinkerers, so if you are not already elbow deep into modifying your airgun, please do not purchase! This system is designed for the Seneca Aspen, ATI Nova Liberty, and ATI Nova Freedom.
I've designed this to be hand fitted, so some sanding of your monocore might be necessary to make it work perfectly with your airgun. Remove a little bit of material at a time and check your progress. I've done this to eliminate o-ring failures and to increase rigidity. You'll also need to drill the hole to attach the shroud to the included rear support. Please feel free to ask any questions before placing an order!
To install you'll need to remove your shroud and the two bushings that connect it to the barrel. Mark and drill a hole in the included rear support for the screw that secures the shroud. Drill it slightly undersized and the screw will tap the threads for you. Slide the rear support down the barrel until it touches the receiver. Tighten the 4 set screws. They should be oriented like an "X" to provide access to all 4 screws. Sand the monocore lightly until it will push through the shroud with a little resistance. Slip the monocore on the barrel and carefully push the shroud to the rear bushing you installed. Reassemble. Again, this is a part for the experienced airgun tinkerer, so if you do not have the abilities or tools to work safely, please do not purchase.
