I have an approved F1 that's been sitting here for almost two years, and figured it's probably time to build it. I already have six F1 cans. They all have a VSR blast baffle and then freeze plugs for the rest. Probably going with cones on this one.

For those of you using cones (for rifle calibers), are you using one for a blast baffle? Or using some flat instead? I ask because of something a YHM rep said about the Nitro vs the Turbo. As info, the Nitro has a conical blast baffle while the Turbo has a flat one (like the rest of their silencers). They limit the Nitro to a 16" 300BLK barrel, while most other cans are rated down to 10".

I do plan on doing SS for the first two, then Ti for the rest...but was curious what most were doing for a blast baffle. A cone blast baffle would mean a longer blast chamber spacer, while a flat one would require a spacer between the blast baffle and first cone.

I run flash hiders on all mine. That's part of my "complaint". Reality is if I had t found the Nitro for $425, I'd probably cancel it and buy a Resonator.

Here's how YHM explained it:

BigWaylon, you're not the first person to ask us about the multitude of barrel length restrictions for the Nitro. Below is a brief write up on our reasoning's.

The reason there are so many variations of barrel length restrictions on the Nitro is due to the suppressor being designed as a multi caliber do-all suppressor. In order to achieve optimal sound reduction on all tested platforms it was found that a conical first baffle provided the best sound results. Due to the geometry of the first baffle it is recommended that the provided Q.D. muzzle brake be used on short barreled rifles in order to help disperse the initial blast to the sides of the blast chamber rather than directing it at the face of the first baffle. This allows the Q.D. muzzle brake to act as a sacrificial blast baffle and dramatically prolong the service life of the suppressor.

The design of our current Q.D. flash hider directs virtually all of the blast into the face of the first baffle. When shot full auto on a short barreled rifle this could cause premature wear of the first baffle. During product testing it was noted that utilizing the supplied direct thread caps resulted in much better erosion resistance when compared to the Q.D. flash hider because again, the initial blast is not being directed to the face of the first baffle.

All of our other suppressors have a flat blast baffle which greatly increases erosion resistance but in some cases doesn't provide the most effective sound mitigation.

I kinda like the VSR blast baffle. Guess I'll look at it a little closer and see how the spacer would work, or how much longer of a blast chamber spacer I'd need.

This. He put a VSR as my last baffle but I have 60* in the rest of the stack. It's a dedicated 5.56 can. It sounds better than my friends' commercial cans with less POI believe it or not.
