A few days ago, I decided to upgrade my firearm setup by installing the Precision Armament Hypertap muzzle brake (5.56; 1/2x28; slim body). Huge shoutout to the gunsmith team at RVS for their expertise and support during this process—they were absolutely fantastic.
Here’s what happened:
When I first purchased my firearm (Crypto), the original flash hider was completely loose. The folks at FOC tightened it properly at the time, but when I later tried to remove it, it was impossible to unscrew on my own. That’s where RVS came in.
When they removed the original flash hider, we hit an unexpected snag. The new muzzle brake only threaded about one to one-and-a-half rotations before completely stopping. We double-checked the specs and thread compatibility—everything matched. It turns out the issue likely stemmed from excessive anodizing on the barrel threads during manufacturing, making it difficult to mount the brake.
Thanks to the skill and persistence of the RVS team, they managed to fully thread both the nut and the brake. However, there’s now a 2.5mm gap between the nut and the brake.
Here’s the big question:
Is it safe to shoot in this condition?
- Should the nut be tightened flush against the brake, or is leaving it as-is acceptable?
- The brake itself is securely tightened and will be extremely difficult to remove.
I’d love to hear your insights and advice!
Again, a huge thanks to the RVS gunsmiths for their outstanding work on what turned out to be far from a straightforward installation.
Looking forward to your suggestions!
