Think I've narrowed it down.
10.5" 5.56, semi auto, relatively light duty. Anyone tested both side by side? Specs are very similar, but not everything shows up on paper. |

I've never shot an Ecco, but I actually shot my 10.5 5.56" last night for the first time with the Polo K. It was awesome. Extremely surprised at the suppression compared to the size. Really love it on my SBR. |

 Budget Price, High End Performance: OCL Polonium K review I really like my Polo K and think it’s a great can. I have no experience with the 5X5, but I have had Ecco chop my Rex MG7K and he did great work; I have no doubt his own cans are excellent as well. Honestly, I’d probably get whatever you can find in stock right now! |

I haven't read anywhere the dB reduction of the Polo K.
Does anyone have reference ? |

Unfortunately, I don't have both cans to compare, but I'll just say that all of my ECCO cans (including my 5x5) are beautifully made and punch above their weight as far as performance. I'm really happy with my 5x5. I know that Otter Creek does great work as well and I've heard a lot of great things about the Polonium K, but there isn't anyone I'd rather buy a suppressor from than Nick and Jerrica at ECCO. (I'd wager that you're going to be happy with whatever choice you make, frankly)

Quote HistoryOriginally Posted By StarCityShooter: Thats what Im hoping. Dont really want to tear apart my LT 12" and replace the GB and tube if I dont have to You won’t have to. For the K all I do is H3 buffer. The geissele super 42 h3 specifically is my favorite but if you don’t want to spend for one of those a basic h3 swap works well with a springco blue |

I’m a fan of short suppressors and the Polonium line seem to get great reviews for 5.56.
Is the K worth getting over the full size? It’s a 1in difference. |

Im not worried about spending the money on the Geissele, I just will not put Geissele in my LaRue rifle I can put it in one of my Aero short builds though if needed |

Quote HistoryOriginally Posted By dmk0210: I have the full size Polo and wish I would have gotten the K (lighter, less back pressure). But I don't think the K was actually out yet when I got mine. Might not have been. The K came out like 6 months after the full size. Truthfully I regret not leading with the K and sometimes I regret not making the K the only version. The K gets a bad wrap just because of the back pressure from the full size when in reality the K is very pleasant. |

Mine lives on a 12.5" midlength. I also have an 11.5 that will be getting a Riflespeed AGB that I think will pair really well with it. I think the problem is a lot of folks don't want to tune their guns with an AGB.  Have you ever considered making a Polo 30 K? |

Quote HistoryOriginally Posted By dmk0210: Well, when you say that, even though I probably should have gotten the K first, I'm actually glad I own the full size. I certainly don't want to give it up. I really just need to get the K also. After owning a bunch of 5.56 cans, I've really started to appreciate K cans in general a lot more.

Have you ever considered making a Polo 30 K? I have a polo 30k at the shop and frankly it just sucks. The design doesn’t scale well when you factor in 30 cal bore + K length. I just don’t feel good putting my name on it |

I just don't feel good putting my name on it I keep hoping someone will someday crack the code and find a magic solution, but the large bore size may just make it unworkable. I'm stubborn, but maybe the better answer is just lighter 30 can cans instead of shorter ones. |

If a H3 buffer and blue spring are recommended for the K, what would that cross over to in the A5 system? H3 is nearly identical to A5 H2 weight but not sure how that crosses over being that it’s a longer system.

The Ecco is bored to accept 6.5 CM, the Polo is 6MM.
Not sure if that'd be a deciding factor for you down the road. |
