Install sucked horribly back when I did it. I could do it now in 20 minutes, now that I have proper tools / knowledge. It's totally worth it ... I'm a huge fan.

Properly lubing your gun prior to shooting is 10,000x more important than cleaning.

To each their own, glad you like it.

I saw that a few days ago, cool picture, I also instantly noticed and smiled.

Right. Enjoy your safe queens, complete with proper paperwork and benelli brochures, as if anyone who actually shoots cares about any of that useless crap.

Thats a whole bunch of worthless crap sitting next to your M4.

I understand. I work the night shift and I like to party, so sometimes getting up in time to make it to the post office is pretty hard ... especially when you can't remember where your clothes are or where your car is. If you can get a PMO out on Monday or early next week, I'll be happy to sell this to you ... I'm in no real rush.

Price Drop - $45 Shipped - Super cheap for what you are getting ... new this tube would cost 3x this ...

No. In my experience, the stock spring works just fine for the 5 rd and 7 rd mag tubes.

Sure do. 1.30 ounces / 37 grams

Thus the continued price drop until the breaking point is reached. Sales 101.

Price dropped to $50 shipped.

Raven is my favorite.

Price drop to $55 shipped.

Price drop to $60 shipped.

Nice collection. Is that mak/tec/whatever it is (I don't follow hood guns) NFA?

4 ports allowed too much gas to push the pistons. They were slamming unnecessarily hard against the bolt carrier and causing damage. Switching to a 2 port design lowered the impact of the pistons on the bolt carrier, allowing it to still cycle reliably but not beating up the bolt carrier. Today, the "low recoil" barrels that are for sale are the old model 4 port barrels, as these barrels will potentially be more reliable when using low power ammo, as the 4 ports allow more gas to act on the pistons, but with low power loads it won't be too much pressure, thus avoiding the excess wear on the bolt carrier. Get it? Kind of awkward to explain. In short: Modern 11707 barrel = 2 port = good for high power and normal loads, should be good for low power and birdshot loads too, but if you're not oiling right / holding gun right / really weak loads, you could potentially have reliability problems. Older 1014 barrel (low recoil barrel) = 4 port = high power loads beat up the bolt carrier, normal loads should run ok, and low power loads will run (theoretically) possibly more reliably than a 2 port barrel, as the gas pistons will be pushed harder. If I was using low recoil OO buck for my HD, I might consider a 4 port barrel ... but if you use all high power loads, 2 ports are better. I don't think you'll have any trouble selling it, as stated, each barrel is ideal for a different situation. I'm not trying to harm your sale, I'm just letting you know that it's not correctly described at the moment.

Low recoil barrels had 4 ports ...

I have for sale a piece of m4 history ... one of the original Nodakspud +2 extension tubes, made in late 2005 I believe before there were any commercially available full length tubes. The Nodakspud +2 tubes remain to this day the best aftermarket option if you are planning on using a +2 tube instead of a full tube for whatever reason (easy swapping for 922r compliance, afraid to use a heatgun, etc). You can see them at http://www.nodakspud.com/ on the bottom of the page, the new ones are color matched to the m4, while my early model one is a rich deep black, a bit darker than the m4. The Nodakspud tubes copy the design and aesthetics of the Benelli factory +2 tubes, unlike the Tacstar and other junk brands. It is made of 6061 T6 Aluminum, unlike many cheaper brands which use low grade steel. I think the design looks a lot better, as it is smooth and threads over the factory limited 5 round tube without a big bulging nut or anything, like the tacstar units have. I'm not trying to sugar coat it, this tube has been used and it shows in a few spots, mostly on the threading where it would be under the magazine tube endcap. I'd rate it's condition as 95%, when installed on an m4 you would only really see one small blemish, which is shown in the pictures. As is usually the case in high resolution flash closeup photography, it looks better in person than it does in the pictures. As such, I'm asking for $45 shipped (less than half of a new one) anywhere in the 48 states. This price reflects the fact that it is used, and it doesn't have a perfect color match of the m4 barrel. If you're looking for a cheap, high quality, OEM style +2 m4 tube, this is for you.

Good work.

All birdshot should fire fine. Question 1) - How many rounds are through your gun? 200+? Question 2) - Is your bolt carrier drenched in lube? Like literally, drenched. I've come to believe that failure to reliably cycle birdshot comes from one of these two factors, each and every time it comes up on these forums. My first M4 wouldn't cycle anything reliably for the first ~150 rounds. Buckshot, slugs, birdshot ... it would fire 3-4 rounds and have various jams on the next. It didn't have a drop of lube on it, as I was a newb and I didn't figure it would matter. 12000 rounds later now and I've yet to have a single malfunction after I lubed up the bolt carrier. I've cleaned it probably 4 times in all those rounds. Between 3 friends and myself, after my initial "dry" m4 fail prone firing, we have purchased and broken in 4 M4's between us. Each of them has been 100% flawless out of the box with every type of ammo, because before initial firing we slathered machine gunners lube or another dedicated high temperature gun oil on the bolt carrier and recoil spring. Member "Unobtanium" on this board has been through 3, maybe 4 M4's by now, and each has been 100% out of the box as well because he knew to properly lube. As such, every thread I see that related to this topic I've somewhat concluded boils down to these two things, plentiful lube and 200+ round count to make sure an overly tight tolerance isn't causing friction based stoppages (unless something is catastrophically wrong, which I have yet to see). So I ask, how many rounds are through your gun? And is the interior recoil spring, bottom of the bolt carrier and receiver rails slathered up with oil AT THE TIME OF THE SHOOT? Cleaning and oiling with CLP a week prior to shooting often leads to a near completely dry gun at the time of the shoot ... as many multi purpose or cheaper oils evaporate at room temperatures or as soon as they start to heat up. Oil right before your shoot, proper lubrication is 100000x more important than cleaning when it comes to this gun (and most other guns, for the matter). If you have 200+ rounds through your gun, and you're lubed up, you should be able to burn through any brand of standard birdshot rounds without any issues. If not, detail the issue here and see if we can diagnose it.

Explain. ?

I haven't been paying attention, sorry bro.
