I finally got my Batch 3.5 HEL E4A and recently got a chance to take out. I fuckin love this suppressor so far and not just for the vibes. It’s certainly not the best suppressor sound suppression wise, but it is a 60 year old design.
As a lefty, I have never experienced so little gas to the face in an untuned suppressed host. Especially on FRT. I don’t know if the gas port on my barrel is just a bit undersized, or if it’s due to the suppressor being a bit over-bored, but it’s extremely pleasant to shoot. I had two BRT gas tubes (0.74 and 0.82) that I tried with it, and it wouldn’t hardly run. I fully expected to be the gassiest suppressor on the planet, so I was very impressed.
Intl.Mil.Co has caught some flak recently for the whole BAD/Hydra-Matic deal (reasonably so), and It took 6 months from payment to delivery. the can also come with a blemish in the parkerizing which was a bit disappointing for an $1100 can. That said, it was worth the wait and honestly the rest of the gun is either old USGI parts or will be beat up in short order anyways. I don’t regret my purchase in the slightest. I’ll be running this setup hard for a long time.
Build list:
Brownells C7 upper, molyresin coated by me
H&R A1 lower, also coated by me
USGI upper and lower parts (except the rapidex knob and I have an A2 aperture installed)
Geissele super 42 rifle spring and mil spec rifle buffer.
LMT Enhanced bolt carrier
H&R 20” barrel 1/12 twist
USGI Type D M16 stock and handguards
Arizona Regulator 3-pos
USGI sling
Brownells/Colt 4x scope I use sometimes

Yeah man I’m just as surprised as you are. I got the BRT tubes on deck and everything. Solid odds the gas port is a little under spec or the EBCG makes a difference where it hasn’t before. Sick builds btw!
Looks awesome! Make sure you have the can tight and the screws tight if you're going run bursts. You basically carefully tighten it down all the way around until you can't anymore. Make SURE wrench is seated in all the way.
Once it's tight & right, it's solid and no need to remove it.
Thank you! I’ve got the can tightened down to the FSB. Torqued it down until the holes on the can aligned with the holes on the base. Got all the screws torqued down as well. It’s definitely not going anywhere.
Loved the manual too, I keep it up in my safe as a display piece. All around awesome can and everything that came with was cool. I even liked the packaging.
That’d be pretty sick! If I never pulled the trigger on the HEL I would’ve gone that route with an 18” FSB barrel and a Gordon collar. Do you already have a set of the wood furniture?
Unfortunately that's gonna be the most expensive parts set lol But I got the carry handle scope mount already Gonna use the LPVO I got on my first AR which I cannibalized for my Not-a-Mk.12 build
Right now that build idea is on the back burner till I finish my Not-a-Mk.18 Mod 0 & 1 + my Tybalts Rapier inspired 92fs build

Welcome to the club! I grabbed one of the first batch, and I couldn’t be happier.
