    Gemtech HALO: inconsistent POI shift; any other problems?

    Hi everyone,

    I'm heavily considering the purchase of a Gemtech HALO. I love its overbuilt design, I love that it has wider apertures for avoiding baffle strikes (I understand this comes at the cost of less suppression), and I love that I can transfer it between my rifles while giving each rifle a different muzzle device better suited for its needs. Overall, I adore (the idea of) it.

    However, I've read that it can create an inconsistent POI shift on rifles, meaning every time you attach it, the POI changes from the last time it was attached. That's a dealbreaker for me, if true. Is it true? And if so, are there ways to avoid it?

    Additionally, are there any other problems with the HALO that I may not know of? I know it can sometimes carbon weld, but I feel that's not unique to the HALO and happens in other suppressors too.

    Thanks for any help you can provide.

    Probably my favorite suppressor.

    Now I don't claim to be a super sniper and I don't use a HALO on a rifle for a precision marksman role. But I have not noticed any POI shift at all quite honestly.

    That said, I am pretty OCD so I tend to place the open area of the retaining collar at 12 o'clock every time.

    I have not had a problem with a carbon weld, but I have noticed if I try and remove it when it is "toasty" it is very difficult (I'm assuming due to metal expansion). But if I let it cool I can remove it by hand without issue.

    I know when it's time to take a brass brush to the interior when it becomes harder to take off the rifle.

    Yes, harder to take off when hot for the reasons you mentioned.

    Did he just use "overbuilt" and "Gemtec" in the same thread?

    I remember when the HALO came out 40 or 50 years ago and seeing pics that SteyrAug posted back on BarfTard. I think those silencers were used in the civil war or Korea or some shit!

    If the 7.5x-thicker blast baffle stuff is to be believed, yes

    I'm curious about something. I remove my suppressor every time I'm done shooting so I can more easily clean my rifle. And while I don't always do a full immersion clean of the suppressor I do clean out the rear mounting area.

    Doesn't everyone do that?

    You'd be surprised. I know I do.... but I see these "stuck silencer" threads pop up from time to time...

    I thought everybody cleaned the mount too... Even on a semi-dedicated suppressed gun I still do it.

    I guess so.

    I've let my suppressor get so bad I can shake out the gravel (seems like broken clay) but I've never managed to actually get one stuck on a rifle.

    I suppose the real question is if people are leaving them on, how are they cleaning their barrels? Are they really pushing all the barrel fouling and cleaner/lubricant into the suppressor?

    Since there is an active Halo thread here, does anyone know if it (the current generation) will work with the extended A2 flash hiders provided they are mounted with shims or peel washers?
