Hi all,
Long time reader, first time poster. I picked up my first rifle can today, an HTG .308 Predator. Overall it looked nice although the end cap was threaded on extremely tight. I eventually got it loose but scuffed the hell out of the endcap when attempting to use the spanner wrench. After examining the baffles, I attempted re-assembling and ensured that the baffles' steps were correctly aligned and that the baffles are in the correct order. However, I can't get the end cap on for the life of me. They claim It should hand tighten to within ~0.020" inch of the tube, and I can't get anywhere close to that, even when using the wrench. I tried calling HTG and their number has recently 'changed.' Not sure if this is because they've been bought by Black Rain Ordnance. Any thoughts/suggestions? Really wishing I went with an AAC can right about now.... Thanks for the help, I appreciate it. |

I put the same scratch on my ARIS so I feel your pain. Do you have the belleville springs installed correctly? If you have the baffles indexed correctly, I can't think of anything else holding it up.
ETA: Try contacting BRO and see if they can help you. Try Here. They've got the suppressors listed on their site already so maybe they can help. |

Thanks,
I contacted BRO but they said since they're unfamiliar with their design to first check with my dealer who might be more familiar with them (they said call back if I can't figure it out). The diagram for my Predator looks pretty poor. I'm assuming from the picture that 'back to back' for the Belleville springs means the two convex surfaces touching in the middle and the flat/concave surfaces facing out? I tried all of the combinations (lightly) and the only one that gets close is when they're nested. |

Great ideas,
the threads worked perfectly without the baffles, glad to know those work... I tried stacking it as well and being very careful to ensure they were 'stacked' correctly and confirmed orientation with a flashlight, still no luck. Since it was ridiculously tight to begin with I'm wondering if they just used too thick of Belleville springs. Think there is any harm in nesting them instead of going back-to-back, or finding a pair of Belleville washers that are slightly thinner? (Would the ATF consider that 'modifying/replacing' parts of a suppressor?) |

Got it! I should have heeded MSC182's advice verbatim. I figured stacking them and holding in my hand would work but apparently it was moving enough to offset the height. Now the baffle stack is perfectly flush with the bottom of the threading in the tube. Still not down 100% like out of the box but it was so crazy tight I don't think I need to get the cap that close again.
Appreciate the help, I'll be sure to report back after I break it in, hopefully this weekend.
