Valkyrie (Rifle)




Valkyrie is a slightly trimmer version of Aquilae and Accipiter.  Boasting the same fusion TIG welded tubeless 17-4 H900  stainless steel construction and baffle technology, it gives up little in suppression compared to it’s “chubbier” bretheren, and is rated for cartridges like the .300 Winchester Magnum and .375 H&H Magnum.  

Why make a .1″ narrower can?  Well, some people just like 1.5″ diameter, and some handguards won’t take a 1.6″ suppressor for those who want to tuck them.
The  standard configuration for Valkyrie is with 1.375-24 Bravo pattern  threads to make it compatible with your favorite mounting system  adapter.

ECCO Machine rifle suppressors are offered standard with no mount for those who wish to run a mounting system other than those we offer.  We feel that there is no need for our customers to be paying for a standard included mount that they do not need or want.  Our Direct thread mounts or taper mount adapters and brakes can, however, be packaged with a suppressor purchase at a lower price point than when purchased individually.  If you wish to bundle mounts or adapters with the suppressor, please message us and we’ll send an invoice with the discounts applied.   We can apply the discounts after-the-fact if you have already purchased the suppressor online.
