This is one of those things where the theoretical meets reality. Out running a Benelli trigger isn't particularly difficult. But other than doing mag dumps into the same spot just to see how fast you can do it, it serves no purpose. (Then you start to play the game of "go as fast as I can without going so fast it doesn't work. You work on your timing and rhythm. Sure it can be silly expensive fun a for a few minutes, next thing you know you wasted 125 rounds and didn't really learn anything. lol) "Damn, I can't do something that never actually happens!" So it's a "problem" that's not really a problem. As to the WHY, it could be that the Panzer is over gassed (and beating itself to death). So the fact that it can do something you don't need to do might not be a good thing.

Like many of you, I waited a long time to pull the pin for a M4. I just received a spanking new M4 LE H20. There seem to be two ends of the spectrum on the first things to do with a new gun, one end is to start blasting away, and the other is to field strip, inspect, clean and lube everything prior to firing. Being of the clean school of practice, when I got to the BCG, I noticed there was a chunk missing from the little o-ring that holds the 028-J firing pin retaining pin. See the pic, beautiful US made mil-spec o-ring on the left...damaged 0-ring on right. No problem, I thought, just order some spares... Welcome to the world of Benelli parts. Midwest has the firing pin retaining pin and o-ring for $6 plus $7.99 shipping, and Freedom Fighter Tactical has just the o-ring for $13 plus $16.50 for shipping. So between $13.99 and $29.50 for this o-ring? And of course, no one, not even Benelli, reveals the exact dimensions or where the o-ring is sourced. An internet search reveals that one common solution is to take the 0-ring to Home Depot, or order something similar on Amazon. The problem is that these o-rings are from China, which is why you can buy those 300+ o-ring variety packs for $10. Neither of these options seem very appealing, especially for a weapon that many owners end up sinking at least $3K in to. I have some interesting experience with o-rings, as I have owned two M35A3 6x6 over the years with the central tire inflation system (CTIS). Each tire has 11 locations that air can leak...and who knows how many more from the engine driven air compressor to the tires. So all this requires lots of o-rings. So when you go to buy parts for these old military trucks, each part has number, and a military spec that goes along with it. The US Army does not use Chinese o-rings from Home Depot. I also saw that some were suggesting Viton o-rings. These are great for hi-temp applications, but Viton o-rings are ineffective below 5 degrees F as they become hard and inflexible. Buna-N seals have superior abrasion and tear resistance, making them more suitable for heavy-duty industrial applications. So, after a lot of research, I found a source for USA made mil spec o-rings that are the exact dimensions of the 'unknown' Benelli o-ring that meets ASTM D2000, MIL-P-25732, SAE J200 standards. The Buna-N material and construction meet strict military standards, are resilient and offer resistance to tearing, motor oil, ammonia, ethylene glycol, isopropyl alcohol and mineral oil. The are sized to the SAE standard AS568. The temperature range is -65F to +275F. It doesn't seem that anyone knows what happens when these o-rings fail. They are called upon to serve as a friction wedge vs their usual job of sealing. The top of the firing pin retaining pin has a mushroom cap on it, and I am only guessing that it could back out until its hits the receiver wall for quite some time. But if it does back out and break, and somehow the firing pin is released...you are hosed. There are plenty of videos on YouTube where the factory rep easily removes the firing pin retaining pin with their fingers. If yours was not so convenient to pull out, and you pried it out with a tool of any sort, you should probably check for chunks out of the o-ring. You can also use a Glock tool to easily push it thru from the other side. There is really no easy way to buy just one Buna-N mil-spec o-ring. So I ended up with a few more than I could ever use. If you are interested in one of these for $3.75 & free shipping, send me an email at [email protected]

This is probably going to sound a bit negative but it’s an honest opinion. Most aftermarket upgrades will not add much if any value with the exception of the mag tube. You would be better off selling those separately. As it sets you are looking at $1800-$2200. You just aren’t going to get 11721 (out of stock) prices out of a m1014.

All good suggestions, I’ll see what I can do

something that is easier to actuate maybe a dimpled or checkered/knurled texture, maybe round but concave to naturally adhere to the shape of the human finger pad it could even be mushroom shaped but as long as the texture is really good! on both sides, I dont like how the left side is a flat untextured small circle

we appreciate all your attempts at innovation! any ideas for a different safety, the TTI and Daves metal works are both nice, but I can see a different design flourishing

I want a sbs one day, and this looks perfect for it!

Never posted before but here is my customized M1014. Have another one I have left as original.

I've since put a t2 on the full stock gun

I don’t have many posts here, so what the heck, here’s a picture of my new-to-me M4. It’s the one on the bag. i was getting a zero with slugs first. My M1S90 is on the bench.

That’s the thing, as a buyer how do you know it’s well done? How do know if the receiver was properly heated and recoiled tube was properly installed. You don’t know if the 7 round tube functions correctly, you don’t know if the trigger housing binds the FCG. The gun has never been tested so you don’t know what you are getting into. Almost every modified firearm I’ve sold the first questions are do you have the original parts and who did the work. There’s always exceptions to the rule but that’s been the vast majority of my experience. most drop in aftermarket mods unless rare or hard to find don’t add no where near the value you paid for them. If separated you can usually get 40-60% of your money back because you have a bigger buyer pool. There’s always the chance someone will buy it for his asking price but with M4s selling on GB for $1400-$1800 (some with 7rd tubes & Adj stocks) the market isn’t very hot right now. I do hope he gets all of his money back but unless he’s willing to set on it until the market is hot again at some unknown point in the future that might not happen anytime soon and it sounds like he need $ now.

Like I said it’s probably going to sound negative but it’s my honest non sugar coated opinion. I’ve been selling and trading guns for 25 years now and I learned a long time ago you are better off parting out your aftermarket stuff and selling a gun as close to OEM as possible with a few exceptions. As for value you can literally get a BNIB 11721 or a m1014 for less than $1800-$1900 with a little patience. If someone has purchased it and modified it, it’s no longer NIB and neither is the price. Don’t take my word for it go to the gun forums or GB and look up the completed auctions and see what they are ACTUALLY selling for (not the listed prices). With the exception of a few newer or rare models most M4s are going for around $1500.

Probably better off removing parts and selling them.And sell m4 stock to get some of your money back.If not as is $2500

Never fired with a bunch of upgrades including mag and trigger makes me uneasy knowing full well how the gun should run VS how it might run if I buy this one. There’s not going to be any accountability or warranty if it doesn’t perform flawlessly

Try slowing down and being more deliberate with shot placement. What's the point of a high speed mag dump anyway??

Start high, that is a sweet thunderstick! I would not ask less than $4500 initially, you can always come down if needed. I'd be surprised if someone doesn't snatch that up.

it is negative and you know it, your flat out wrong with the suggested pricing not to insult you, but your post is insulting, there is no way that m4 sells for that low, no way anywhere on any day. crap post. this "after market parts dont add value" rhetoric is some fudd lore non sense, what are you talking about? so a $240 Geissele trigger added to an AR15 that came without one, adds no value to you? an Agency handguard and a Geissele hammer add no value? a collapsible stock adds no value? only a 7 rd tube? 🧐
