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. Just find and add the mount you desire to the cart and the applicable discount for the bundle should automatically apply.

Price: From $499

Once we have that information, we will file a Form 3 dealer to dealer transfer and ship your suppressor to your local licensee as soon as the Form 3 is approved, and they will handle your Form 4 transfer from there.
