Have you used one of these? I went to the site and I’ma little unclear about building the baffle system

I’ve done form 1’s before. I’m just curious about the baffling for this system.No I haven't. Unfortunately I live in a state that I can't own one. Do some research on form 1 suppressor. Tons of info and a friend of mine just moved to Montana and filed for his form 1 and was good to go in 30 days

Should be plenty. You can get a rough idea of port size if you have a decent selection of drill bits. I have a BA SPR barrel that had the same issues. Port was .07ish, had to drill it to .09ish to get function..0935 is what ballistic advantage tells me. I don't have pin gauges to verify
That’s a better port size than the .1-.105 called for in Mk12 specs as most here aren’t in need of Arctic capabilities..0935 is what ballistic advantage tells me. I don't have pin gauges to verify
Absolutely. Let us know what you come up with.I only have a handful of tungsten weights in order to dial in a 300BLK pistol and that's only going to make the buffer heavier anyway. I've been wanting to go with a JP setup since I first saw them and it looks pretty customizable so that's the route I'll most likely take if it comes down to it. Thanks for the tip. I had considered getting some aluminum bar stock and cutting lengths to swap out steel buffer weights to see what would happen, but I also don't want to cause premature wear on internals. First I'll verify again that air is moving through the system, but I'm confident that it is, then try the 77gr ammo, then mess with weights.
So BA is known to jack up port sizes at times...just might want to check...So here’s where I am so far, still need an optic. No where near clone correct but it makes me happy. One major problem though, it’s not cycling correctly. Ejects spent case at 3 O’clock, bcg doesn’t lock back on empty mag or load a second round. Air moves freely through the gas system with a plugged chamber and air introduced at the muzzle. I only fired 5 rds of Win M855 through it. BCG was torn down and oiled properly prior to testing.

Doesn’t seem right. What do I do?
Specs:
Aero upper and lower
Aero NiB BCG
BA premium 18” SPR contour barrel
Rifle length gas
CMMG gas block triple checked for placement and carefully dimpled for set screw using a dimpling jig
Mil-spec internals/recoil spring/rifle buffer
Allen Engineering brake and collar
What optic did you decide on getting?Hey guys, just an update real quick. I was able to hit the range today to do some testing. Still don’t have any 77gr. yet, but I wanted to shoot so I went out. I messed around with buffer weights. I acquired some .500” aluminum round and .500” delrin round. I don’t have a digital scale but I do have a cheap powder scale that only tells me grains. For scientific purposes, I measured out .600” lengths and cut the rods. Aluminum weighed in at just about 81 grains. Delrin was just about 42.5 grains. Fun project but swapping weights in the buffers did nothing for me to be honest. After fooling around for about 80 rounds the rifle started acting right, meaning it was stripping the next round off the mag and locking back on empty. I had the same issue with the M16A1 clone in the photo. Using Okay Surefeed 20rd and magpul M3 mags, the A1 clone is reliable in my mind, the Mk12 is still a little shaky but seems to be running much better. Nothing I own runs with tulammo, shocker, but seemed to be ok with PMC X-tac, did real well with M855. I’m hopeful with 77gr and now maybe parts are mated, things work well. I was running the bolt fairly wet with Lucas oil and it seemed to get gummy once dirty, not to mention it was only upper 30’s today, even though Lucas says -38*F. I don’t know. I cleaned everything and put light coats of Lucas CLP on everything. I’m waiting on an optic and the 77gr for the next outing and see how it runs. Today was a glorious escape.

I decided on the Primary Arms GLx 2.5-10x44 with the FFP ACSS Raptor reticle, with their corresponding mount. It seemed like there were a lot of pretty good reviews on it across the net and I didn't really want to spend more than what it costs, especially since I have another rifle that needs some kind of optic as well. I'm sure it will fit my needs just fine. I'm currently shopping around for something 1-6 or 1-8 for a carbine. Sitting on a couple hundred rounds of 77gr to try out once the optic arrives Monday.What optic did you decide on getting?
That's a darn shame.It used to be one of the Navy's best kept secrets, until the mid 90's it was mostly word of mouth. We still have a problem in that ship's and commands don't support it even as a no cost TAD, marksmanship isn't seen as vital to the ship's mission, and even falls victim to an anti firearm bias in some chains of command.
We used to have a lot of Coasties in Hampton Roads that shot with us. We still have a couple. Maybe we all shot together one year.That's a darn shame.
My brother shot both PAC and LANT Fleet and the All-Navy as a Coastie. I started in 1999 as an (Army) invited guest and went Distinguished. I learned a shit-ton from the Navy teams (both East and West Coast) and shot with a LOT of active and retired sailors.
My first experience with 77s came from the Fleet Matches. All shooters (regardless military or civilian) drew Crane-issued commercial HSM 77s or M118 7.62. If you didn't have data you'd better at least be centered-up and zeroed.
I think part of the Mark 12/SPR's mystique came from the fact that on 9-11 it was really the only hot-rodded M4/M16 hyrbid generally available to "Vanilla" (non-JSOC) SF/SEALs that was free-floated and had a reach advantage with different variable scopes that were not ACOGs or rare 1-4 Schmidt-Benders.
Hey Boone, can you give me some specs on this little guy? curious on barrel length, gas length, and handguard length. Thanks!And his little cousin.

I shot Atlantic Fleets 88-94. Shot All-Navy 88-94 with exception of 89 when I was recalled to the boat. Shot Interservice Rifle in 91 and Nationals in 93. In 91, the All Navy's were at Camp Pendelton, CA. In 1990 they were at Dam Neck and the PacFlt team shot on the East Coast. I think 94 was the last All Navy in a single location at Dam Neck. The guy who took the top Active Duty Grand Aggregate was CDR RJ Thomas, a Vietnam Navy Cross awardee (as a PO2 SEAL) who fought off VC with just his M1911A1 after a helo crash until help arrived.We used to have a lot of Coasties in Hampton Roads that shot with us. We still have a couple. Maybe we all shot together one year.
I just shot that ammo the other day from my Mod 0 with @TheGerman . 2752 avg, SD 18SG Ammo has their Mk262 in stock from IMI, got in some yesterday.
That's because you're probably a youngster and maybe not in-service.Sorry, all I feel is, "Meh, just another fucking AR!".
You are lost...Sorry, all I feel is, "Meh, just another fucking AR!".
True story. I first saw Mk12 Mod 0 in Iraq in 2005. Some ODA cats were next to us on the FOB in Hiit, and I was like "OooHHhhHhhh what's that cool thing?" Those guys were doing some serious work in town almost every night.That's because you're probably a youngster and maybe not in-service.
Before and just after 9-11, the generic military person's options were M16A2 or M4, and not many options to add accessories.
So, for those of you that haven't reloaded for the PRI Mod 0 upper with the Douglass barrel:
The chamber is probably a minimum spec. Even the 1x fired brass could be easily pushed into my Lyman chamber check gauge. Just needed minimal work in my Mighty Armory die.
