The best luck I've had is a combination of the USPS postal inspector and the local PD making a visit. The latter doesn't always happen since some PDs are too busy and won't even take a fraud report. Other times, if they hear about one fraudster multiple times, they'll act on it.

I don't have any personal experience with it however I've heard it does a good job of keeping the muzzle flat with some redirected sideblast though not as bad as the FSC from PWS. My problem with muzzle devices is most demo guns are fitted with either an AAC flash hider or muzzle brake since those are the suppressors I sell to local customers and they want to hear the cans on the demo guns typically.

So this is how I built my SPR upper. Keep in mind that while this serves as a company demo for local customers, I wouldn't keep it like this if I didn't like it personally. I'm doing some copying/pasting from the pic thread. Upper Receiver: Complete PX Forged Upper Receiver Barrel: ODIN Works 18" 3-Gun Stainless BCG: WMD Guns Full-Auto Profile NiB-X Handguard: 14" Centurion Arms CMR w/ bipod stud Charging handle: Rainier Arms Raptor The only thing I wouldn't be able to provide is a pinned/welded muzzle device. While I stock brakes, I'm not setup to do the work. So why do I like this build? 1. It's accurate. ODIN guarantees these barrels to be sub-MOA and they are. I've sold quite a few and haven't heard a single grumble about their capabilities. 2. The balance is perfect. Even with a longer handguard and a longer barrel, the rifle balances at the magwell. This makes for easy off-hand shooting as well as fast transitions. Lightweight handguards and properly profiled barrels are key to managing the distribution of the weight. You don't want something front heavy if you intend to shoot it off-hand. 3. While these are premium quality components, nothing is really over-the-top cost-wise. The CMR is the most expensive part at around $300 but if you think about it, you're building what is essentially a match grade upper that can double as a CQ upper for under $1K.

I could do some shameless self-promotion

Not any with personal experience, no. I do like the Odin 3-Gun barrels as they're guaranteed to be sub-MOA (mine certainly is as is one I sold to a close friend), come with a gas block and gas tube for under $300. They aren't a rifle length gas system though and use an intermediate gas system which is about 1" shorter than rifle. They weigh a little under 2.2lbs and are extremely well balanced. There's also White Oak Armament and Rainier Arms who have 18" SPR-type barrels with rifle length gas systems.

It's a much more extreme measure than what CA is required to use. I believe the MR2 is NY SAFE compliant as I've sold quite a few to NY in the last few months.

So I'm curious about how an AR MR2 maglock would fall into this chart. For those unfamiliar with the MR2, it replaces the magazine catch and button with a two piece system as seen here: The mag catch is secured to the redesigned release with a hex head screw. The manufacturer's directions for permanent installation is to use red loctite on the threads then drill out the hex head once installed. Once installed, to depress the magazine release, you must pull the takedown pin and pivot the upper receiver away from the lower. This exposes the magazine to be either top-loaded or you can hit the mag release and it will drop.

With 3.5" more barrel and the same gas and recoil systems, yes, you will notice it's a good bit sharper in recoil.

Yes but it may ultimately cost you more money. A quality A2 extension kit can be had for $35 and is more or less guaranteed to work without further tweaking regardless of gas system (mid or rifle). Most heavier buffers are $25 to $35 and may or may not achieve your objective. Some adjustable gas blocks are even more than that. See what I'm getting at?

Likely harsher though dependent gas port sizing. My 18" midlength with an A2 recoils harsher than my 16" midlength with an H buffer.

The longer the gas system, the softer the perceived recoil as the rifle isn't cycling as fast/violently.

You can. I've built a couple 18" midlength guns that use A2 extensions without issue.

Yep, the Luth uses a standard riflelength extension.

Thanks for the order! Looking forward to seeing it built up!

If it was my rifle, I'd go with the A2 to keep headaches at a minimum. I prefer shooting to troubleshooting

If you use a carbine type buffer and action spring, you could run into cycling issues, yes. Additionally, your center of gravity on the rifle is going to shift forward and run the risk of the rifle feeling muzzle heavy.

FYI but QB is Intuit which is pretty anti-gun. You'll want to be careful as they can can your account and hold your batches for months.

I ship thousands of firearms per year (mostly receivers) and that's what I do. I don't provide a signed copy of my license unless I know I'm receiving a firearm. This is because I don't transfer firearms that weren't purchased from me as I don't have time for it. I had an issue last year where someone was sent a signed copy of my license with a shipment that I sent and they didn't bother contacting me in advance when one of their customers ordered a firearm and had it shipped to me without my knowledge for transfer. The logistics headache that resulted is why I no longer send signed licenses.

You can land in hot water with the feds too since LE guns don't have FAET assessed and collected.

Do what I did and delete it. I tried pushing the sear pin out to make it fail with the safety gone and it won't.

Yes and no. You can get them for less if you're in a buying group.

Nothing wrong with the sender including an unsigned license. As the sender, they're required to obtain a signed copy of the recipient prior to shipping however you as the receiving FFL can check it in with their DBA and address. Copies of licenses with firearms are an industry custom but whether or not they are signed has no bearing on your ability to check it in. They sound like a noob shipper. Those fit in a Regional Rate which are a couple bucks more than a padded flat rate and wouldn't require such mistreatment of the merchandise.

Haha, no worries. If it makes you feel any better, you are far from the first to mix us up.

Yeah, the ACT LPKs are in stock, we've got a bunch. The first link you posted, the one ending in 659, is what you want. The second link is to Midwest Industries, a completely different company. Unfortunately, I don't know anything about the Wheaton comp. This is actually the first I'm hearing of them.

MBUS sights are decent though I would spring for the Pros due to their extremely small footprint/profile. We've got the ACT LPK for $85.95 and the FSC556 for $94.95. Purchased together, you'd get free shipping to boot. If you were interested, we also have the MBUS 2 rear for $49.26 or a the Pro for $89.21
