I'm probably gonna pull the trigger on a Griffin Armament. 338 can for my DTA.

My primary concern is accuracy and consistency. Durability I'm sure isn't going to be a problem. Besides, I'll be shooting mostly underpowered rounds for what it was designed for...... 7mm Magnums and subsonic 338s.

So has anyone done an accuracy test of the top names in precision silencers that includes Griffins offerings. Maybe testing that shows how they hold up and are they consistent as they heat up. POI shift?

Thanks for any feedback. .
 
We have done POI shift tests ourselves, granted we are biased and so it really means nothing to the consumers. However Fate of Destinee did a youtube video and POI demo with our RSTA can on a APA rig and it showed very minimal POI shift. SNIPER RIFLE TRAINING for FateofDestinee from In Extremis Consulting Group - YouTube its kind of a long video but you will see her demo a POI in there. It was her first time shooting a precision rifle she did really good considering.

The shorter and stouter the barrel, the less shift will be present. The longer and more slender the more shift. The suppressor is basically a barrel weight and will drop POI due to that. This is why you can throw the same can on multiple hosts and see different results with each individual rigs. Factors that influence shift are weight, mounting systems (solid lock up or not), accuracy of the bore line of the suppressor, and baffle geometry (some baffle geometry can negatively effect accuracy or POI shift). We feel we have covered the bases well on these factors to bring suppressors to market that mitigate as much as possible POI shift.

I tested a 300Mag PHS with POI off a Tikka T3 with a fairly slender 22" barrel contour (not sure what it was) and it was 1/2MOA shift, this RSTA on a #7 profile 18" barrel was about 1/4 MOA. Well made suppressors should be have minimal and repeatable shift, but people have to also understand that the platform will influence POI shift as well. In terms of consistency as they heat up... I have not seen anything with our cans to suggest there is an influence. But I have talked to a competitor on the PRS series that requires a very high level of precision and he said that he has noticed some cans will do this. Either a cold bore can shift or a shift as they are fired or something to suggest an inconsistency issue. I'm not talking about our cans I just know that phenomenon is perceived by some high end shooters. He won't run a can in competition though due to the fact that he feels any can regardless of manufacturer will be negative for competition environment.

I think it depends on the competition or level thereof. I competed in sniper comps in the military and I knew some people that shared this opinion, that cans were too inconsistent in a comp environment. I ran cans on my sniper rigs and beat many of these competitors that didn't run cans. I knew where my shift was and zero'd with my can on. I never removed it and I didn't see anything unusual in my ballistics that effected my desire to run with the can off.

Thanks for the interest in our products.

Thank you for your reply.

I think from a competition perspective the only reason I won't run a can is just weight and maneuverability. The shorter and lighter the better for me.

This will primarily be for hunting purposes.


I guess POI shift from putting it on or taking it off doesn't worry me. There's no way I'd go hunting without zeroing anyways.

As far as grouping between with the can on or off...... Well I can't imagine your silencers degrade accuracy in any way. Your mounting systems seem very robust so I'm sure the accuracy I'm looking for will be there.


Now if you could just do something about the NFA wait times.

:(

We are meeting with congressman Paul Ryan next monday to talk about the gross negligence of the NFA branch as well as other things (all pointed towards NFA reform). While a bit of a rhino, I've spoken with him in the past, he is aware of the ASA's efforts for an NFA overhaul and has been speaking with other key legislators about the NFA modernization Act. I think there will be a light at the end of the tunnel to transfers soon. The current administration is bent on targeting the firearms industry and that is another problem. We are doing our best between manufacturing, sales, and promotions to try to get involved politically in NFA reform.

The Paul you need to be meeting with is Rand.

We are not meeting with Ryan because he is Ryan, we are meeting with him because we are constituents in the 1st district of Wisconsin which is his territory. I wish it were still Sensenbrenner as he actually met with us on time and notified the NFA branch director personally of problems with transfer times, etc. They moved geographical territory around in the last election and our business is no longer in his district.
 
Does Griffin have their 338 cans in stock? They usually have pre-sales where they have to sell so many before they make a production run. I have a Thunderbeast Arms 338P-1 I really could not justify trying to save a little bit and risking getting a suppressor that was not designed and built for long range shooting.

Yes we have cans in stock ready for transfer. Quite a few actually. We got out of the business of doing pre-orders as it was an admin mess. Our PHS suppressors were designed and built for long range shooting.

TBAC makes nice products from everything I have heard and read. I haven't handled them so I don't honestly know how they compare to ours. But our products are high quality as well. I wish I could personally demo with everyone that doubts our products but it is obviously impossible to do so. That being said I understand that there is always doubt on new product releases. As our products circulate i'm sure some people will share in their experiences of our suppressors. Thanks

I have a FFL/SOT send me one of your cans and if I am as impressed as you say I will be I will pay for that one and order an additional one, if I think its less than impressive I will F3 it right back to you with a 100.00 bill for doing the paperwork and "demoing" your can.
 
Any updates? Very interested in the .338 PHS and how it compares to the TBAC. PHS is MUCH less expensive as the TBAC and more importantly it seems to be in stock. I'd also like to know how it tames the recoil of the .338.

Here is a really informative video that one of our Texas dealers did with the PHS300 suppressor. It should answer most questions. If you have any specific questions PM me or you can post here. Also RangerWalker is a dealer of ours here and might be able to give you some information on them as well. I don't know how our cans compare to TBAC i have never seen/handled/shot their suppressors. I hear very good things about them though.

Thanks! Very informative and makes a strong case for the Griffin. Looking at one of these in 338 and they're close to being 1/2 what the TBAC retails for. Definitely worthy of consideration!
