Sadly it is so. https://orchidadvisors.com/compliance-with-18-usc-922r/

This is the absolute cheapest way anyone will SBS their M4. It's an idea that will sell just fine. The pistons are what break, after many tens of thousands of rounds. The gas caps, eh, spares are spares. If you want to use your long barrel again, nothing more is required than field-stripping to transfer the pistons/caps back.

I am contemplating buying a spare barrel for my M4 SBS, so I can take the gas-caps and pistons off of the barrel for spares (I have a significant stash of spare parts, but missing these). I would then offer the LNIB barrel (minus pistons and gas caps, but INCLUDING FRONT SIGHT) to this forum for sale. It could be used with your 18.5" pistons/gas caps, once you Form 1 your Benelli M4, and would be the cheapest way of obtaining an SBS'ed M4. What does the hive think such a creature would be worth/what is someone willing to pay?

FliteControl's first victim.

Your review is similar to what I expected, based on looking at it.

You've still got a lot of people with legacy and Malkoff/Arisaka models. I still see M600A's for sale from time to time...

Dunno why I didn't see that before! What is the clearance on the lug vs. pocket? I really like that. Will the MOD 2 accomodate older scout bodies, as well, or moving forward will it only support the newer ones?

Can you or someone post a photo of this scout lug/AVA interface? Does this imply a "MOD 2" in the works? Love your company, your CS, and the product is extremely well finished. If/When the MOD2 comes out, I'll certainly look into it.

Zero shift every time you remove the clamp, potentially, barrel distortion/deflection, etc. I'd just not, honestly, but YMMV. If you do choose to clamp it and clean it/remove the clamp: --Steve Rose

I've been waiting for someone with some common sense to buy a Hayl and review it. From what I gather: If you don't use the set-screws, it's going to flop all around and mar the gun in various places. If you DO use the set-screws, it is no-longer toolless to take the weapon down for cleaning, etc. Can you comment further or correct me?

Actually the last one I read about was a .308 with a SPUHR mount. Hakkan himself posted in the thread, and suggested rosin be used. The one thing we ALL agree on, is that compared to 2010, things are doing great for light mounting!

I have the same setup (waiting on NFA), and am going with the IWC. I prefer the IWC because it's lighter, and provides the same functionality. It is the cleaner option in MY opinion. It also properly mounts a SCOUT light instead of relying on compression/tension from compression around the light body. It does rely on compression around the barrel hanger, but it is also keyed, as it fits in the recess where the sling plate was. To me, these things matter for a 12ga weapon. Noone has ever broken either, so less weight is less weight, ultimately, is my take. To me, the AVA looks overly complicated because of all the fittings, and the weak link is the compression on the Surefire body. People complain all the time about scope rings not holding scopes to .375 H&H magnums (similar recoil to a full house 12ga load), and yet here we have a MUCH LESS PRECISE fitment than precision line-bored rings and a honed optic tube, and one ring to boot. It just...bothers me. So I stick with "keyed" mounts like the Scout series, which the AVA pretty much removes from functionality. Also, as noted, the barrel hanger must be 100% true to the barrel, which of course is ideal and all, but not really "necessary" to be strictly honest, for the function proper, of the shotgun. The AVA mount, however, requires this. Any deviation from it reduces the strength of the joints. The IWC mount on the other hand isn't so picky, unless the hanger is severely under-sized, which I would wager is a wee less likely. Also, the IWC allows you to keep your shrouded tail cap. AVA won't.

Now...on to the technical stuff as relates to the Benelli M4, garnered over 5+ years of their experience with a Benelli M4 SBS... -1/22/2017 -8/29/2016 This quote should give you an idea of the volume they see at their range...consider the economics at play, here... 9/11/2016 -1/5/17 -1/22/2017 -2/19/2017 -3/26/2018

Some of you may, or may not be aware of Henderson Defense in Las Vegas. They were nice enough to communicate directly with me via Facebook to bring me this data, so I want to give them a shameless plug before we begin the data, as well. They're a good company, run right, and benefit our Veterans as well as The Public At Large. (All text-blocks as quotes are attributed to Ron, the VP of Henderson Defense/Battlefield Las Vegas, and have been posted as best I can to preserve the context in which he made said statements). https://www.battlefieldvegas.com As I said, first, a message from Ron, the VP, to give a glimpse inside his business, and who he is as a manager/VP. This was posted in 2015, and his business has increased in volume exponentially since then, so his employee count, etc. is likely no-longer close to accurate. To put into perspective just how large his operation is getting to be, they just bought a new (to them) M60A1 tank, with functioning main-gun, they own an M134 which you can fire, etc...

I'm at that 5'10.75" nowhereville, where you're not short, but you gotta lie on your Tinder profile because real men have heights that start with a "6", but XL clothing that fits your shoulders and chest hangs down too low, and apparently Benelli hates you, too.

Can you use that stock on the mid setting, and still see the dot immediately in the RMR? I ask because it should sit higher than irons, while still very usable. I know you don't need it on mod setting, but if you're handling some, could you check? Curious if using this setup will allow me to use mid setting on the stock and be G2G. I know irons I hurt my face, but I *can* do it, it just isn't comfortable at all.

I'd not clamp a +2/3 extension. Not worth the downsides.

The batteries remain in place during recoil, while the light moves rearward. The result is the compression of the spring on the "head", and relaxation of the spring in the "tail". The scouts are well made, and neither action causes loss of contact/random switching. That said, those batteries are hitting each other, as well as the head, each time you fire the weapon. CR123's don't like physical abuse. It's likely a non-issue, but I prefer to cut the mass in half, and reduce the moving parts by half, as well. Again, I'm likely overthinking this, but the math does agree.

I'm using the 14" barrel, so you're gaining 1.5" of light, roughly, while I'm losing 4.5" of barrel. On my 18.5" m4, I went m300 because I simply like the light having less leverage on the mount during recoil or slamming into anything, as well as only 1 battery in the stack vs. 2, to be slammed back and forth against the springs during recoil. Primarily, these lights were made for 5.56 caliber carbines. Not that theu arent super durable, but the shotgun IS outside of their optimal parameter. The less abuse the battery stack endures, the better, imo. Cr123s don't like being beaten up. Most of these are technicalities that live in the realm of theory, but the m300c with 500 lumens is enough light, and my thought process is logical, so I roll with it.

500 lumen M300C IB with 1.25 bezel....dream unicorn!

This is the product the Benelli shotguns ship with. I am curious to learn more about it. So far: -NO CORROSION AFTER 200 HOURS IN A SALINE FOG CHAMBER source: http://www.brignoliarmi.com/698/hunting-articles-beretta-accessories-guns-oil-oil-unifluid-allgun - It cleans, lubricates and protects. Dissolves the residues from the combustion of gunpowder. Anti-rust, eliminates moisture. It remains fluid even at -32 ° C. Source:http://www.armeriacorti.it/it/prodotti/pulizia/olio-mf-82/6262

Nice! Yeah, those on sale for $1900 were a pretty slick deal!

Hang on to your c stock and flip it when the time is right. Honestly what you propose is a PITA, and the m4 c stock just isn't that hot.

Did you re0pace them with oem, or were Wolff springs available at that time? I recall you saying own springs are not the best, but have you run the Wolff long enough to opine on whether or not they are better?

The carriers both have rails that require the cutouts so they can be removed from the weapon as they are not captive assemblies. The m4 carrier impacts the rear of the receiver.
