Zealot Rifle Chassis by KMW

@Terry Cross would/do you recommend skim bedding in chassis generally?
I would totally recommend doing anything that would make the finished rifle more accurate, more consistent and more trouble free.

If I thought that skim bedding the Zealot chassis helped, I would bed every one I built. On an already expensive rifle, there is no reason I would omit a step that would improve the rifle for my customer.

I don't bed any of the Zealots.
Also, like the IMB, they are not sensitive to the torque on the stock bolts and they shoot small.


The IMB is an internal chassis I designed and use in almost all of the SENTINEL stocks. I was not a fan of such and had no intentions of trying that but I had a project to compete for a while back that had a "no bedding" requirement. I had to design the IMB to compete for it. It worked really well. I refined it over a few years and for the last 10yrs every SENTINEL or LongSword rifle I have built uses the IMB bonded into the SENTINEL fiberglass stock.

When working on the CAD for the Zealot project, I wanted to bring over all of the proven tech that was applicable from the SENTINEL project. The SENTINEL IMB as well as the SENTINEL DBM bottom metal was merged into the Zealot chassis. Both are proven across a pretty rough user history. As was hoped, both of those aspects have worked perfectly from the start with the chassis project.

If I had to hazard an instance where this chassis might benefit a skim bed, it would be if the user mated a factory Rem 700 receiver to it that was particularly curved and inconsistent on the exterior surfaces. Maybe.

For all the other actions out there, I would say bedding probably wouldn't hurt but I would also be surprised if you could quantify any improvement either.

History may prove me wrong but so far, not.
 
Any chance it’d work with a Coup de Grace without having to mill it out due to the trigger hanger?
The chassis body is designed to allow trigger hangers but I have not had access to a CDG action or CAD file, so I cannot make a solid statement about the ARC trigger hanger clearing. Area of concern would be the rear of the trigger hangar where they put the large socket head retaining screw.

The chassis body for sure clears the Impact, Tempest, MacBros and BAT.

Once I get an action or solid model of the CDG*, I can render a statement.

*ARC tends to change things along the way. If they have a different iteration of the hanger or the hanger retaining screw that is Pre or Post production of whatever I inspect, there could be a problem.

I just got my first KMW Sentinel last night and I immediately tried to fit the Coup De Grace. The stock has the Integrated Mounting Block and the trigger hanger does not fit as is and will need milled. The screws used to secure the trigger hanger hang down even lower than the block and I may try to replace them for a more flush fit. The stock is a few years old and I do not know if the design has changed since it was made but as is I am going to mill it to fit.

The second part to think about is the coup de grace is really made to run with the AW mags, and the AW mag fits and appears to be the right height with the KMW bottom metal but if you plan on using aics, per ARC's website "AICS magazines will require a shorter than standard magazine latch". Again this is in reference to the Sentinel and not the Zealot.

Also the cad files for coup de grace can be found on arcs website here (https://www.americanrifle.com/shop/...ion-1747#attr=491,494,495,519,512,522,514,516)
