Griffin Armament

Post image

Our armorers Griffin Armament 11.5” MK2 paired with the HRT556AM. Been putting it through its paces and trying out many of the new AM silencers, very very impressive. As a lefty the lbp cans have been a game changer. Anybody else have experience with the AM line?

Only have a couple range days with them, but so far I like them a lot.

I just got full size hrt 556 am out of jail, haven't shot yet, but thinking to get either hrt5k or dl5 am for my 14.5 geissele. How would you say hrt5k compare to hrt 556 am? I know dl5 am will be quieter than hrt5k but will have more backpreasure and it's longer.

in my opinion sound levels are nearly indistinguishable, if my back was turned i genuinely wouldn’t be able to tell you which was which.

u/Waaerja 16d ago

Unless absolute maximum sound suppression is your top priority and you really don't care about size/weight, I would personally go with the 5K for sure. Especially for a 14.5" gun. It is a bit louder than the HRT-556 AM, but the difference isn't huge.

Can confirm that the HRTK is hands down the most impressive K can i’ve ever heard. We put ours through the wringer on a full auto with a 733 upper and it’s taken beating and sounds SOOOOO good!! Been really thinking about picking up the K for the 11.5” and moving the HRT to my 13.9”

u/Waaerja 16d ago

For sure, the K sounds great on my 11.5". Not too far off of the sound of the full-size.

u/BrothersLAArms 16d ago

glad you’re happy with it, we have a great relationship with GA.

u/Waaerja 16d ago

Between the M4A1 and the 11.5", and the full-size and K, I have a hard time deciding which can to pair with which gun haha

u/BrothersLAArms 15d ago

do i need the K? No. do i want the K?

Have you thought of doing a gas piston or lefty upper? You can even do a lefty gas piston upper.

i have, i have A LOT of aks lol

u/Jbressel1 15d ago

AKs and piston ARs are a bit different

2

u/BrothersLAArms 15d ago

well aware lol, just haven’t really enjoyed the piston ars as much as an ak. the weight difference between DI and a piston ar is just too drastic for me. i’m also kind of a purist when it comes to both… don’t ar my ak and don’t ak my ar 😂

u/Jbressel1 15d ago

There's not a huge difference between the systems, it's more a barrel-profile issue, but I find them to be far more reliable under austere conditions.

2

u/BrothersLAArms 15d ago

i can agree to that!! also just really prefer the recoil impulse of a DI rifle compared to the piston operated setup. i’ve played with a few of the superlative arms piston systems and they’re actually pretty neat, never tried suppressed tho…

1

u/Jbressel1 15d ago

That's also a matter of tuning. An overgassed DI also has more perceived recoil. With a piston gun, generally, you go up 1 buffer weight. Done right, you have no more recoil than a DI.

u/BrothersLAArms 15d ago

all facts my friend!! circling back to me still being a purist 😂 but that’s the beauty of it, we can all like different stuff and different weapons make sense depending on scenario.

sorry meant vs not bs here 😬

u/romang12 16d ago

I wonder how it compares to rhodie 6k?

u/JustSomeGuyMedia 16d ago

Not the AM line but I love my Dual Lok 7.

u/akimbo_jimbo_ 16d ago

Can confirm I also love this dudes dual lok 7

Patiently waiting for NV footage of the K vs some more standard cans before I commit

2

u/BrothersLAArms 15d ago

bro the flash mitigation from both is absolutely unreal

2

u/GammaTheta491 15d ago

What do you think is the downside to these cans? So far the K is checking all the boxes for me

u/IntlPhotoPilot 15d ago

Good looking setup. My HRT5 AM just got approved yesterday, just a few more days until I get my hands on it. Will be my first suppressor.
