If you are wondering what program I use for the creation of this video, please check the description. It should be included on every video in this series, if not let me know.

They way the x-ray series is done is exactly how visual learners pick things up. Phenomenal job! Are you still making these? Everyone I've shown this to was blown away...no pun intended.

Mossberg and 870 both have locking block roots in the remington model 31 and probably the earlier remington 1917. By a convoluted lineage the mossberg has it because it copies the high standard, in turn a copy of the remington model 31. It be cool to see the old Marlin pump shotgun animated to see if its like the 1897. Not the more boxy marlin but the earlier external hammer fired marlin pump shotgun.

I enjoyed this series. A request: please show a top/bottom comparison of how the safeties work in the 500 vs. the 870.

There's a bit in the 1897 that keeps the carrier from dropping if the hammer is cocked. You didn't cover it.

Excellent video! (perfect amount of talking). QUESTION: With one fired shell in the chamber, I am finding that the pump action is stuck in the closed position. What do you think is the culprit here? - I have been able to free the action with a fairly firm bumping of the butt on to the ground while keeping downward force on the fore end. Sometimes takes more than one strong bump to open. Something is preventing the action from opening. ??? -- Could it be the action bar lock? If so, how can I tell? Thanks.

How to load the gun. In the 870 with the shell

@tropocal2343 7 жыл бұрын

Thank you for *The Only* video out there, showing the shell stop function. I'm trying to figure out why my 870 express FTF, on account of the left shell stop not moving out of the way to let the shell out of the mag tube. 23:14 I repeat cycling sometimes 2 or 3+ times, before I can get a shell loaded. It's very disappointing to realize your beloved HD modified 870 isn't as reliable as it has been revered to be. Hope I can restore it, and figure out why it occurred in the first place. - (Fix it remedies welcomed) I appreciate your thorough and concise explanation. Otherwise, I'm acing it for a VEPR or a KSG. WTF has happened to Remington?....Taken over by anti-gunner group? I digress - *Thanks again!* Thumbs up # 45 & subscribed.

you can't really make out head or tails of the mechanism without the narration,but you could improve on the script since sometimes it's kinda hard and confusing with the back-and forth talking.nonetheless,your videos helps a lot,making it a whole world easier to make a prop based on.

There's no cutout all the way through the barrel for the 870, that's only the Mossberg that has a square window at the top of the barrel extension. The 870 has a divot in the barrel extension that the locking block fits into. While the Mossberg has a window all the way through barrel extension, the locking block doesn't go into the aluminum receiver that I can tell. Haven't looked inside that part of the receiver closely enough with barrel removed. On the 870 garranteed there's no opening in the barrel extensionr! Receiver only has cutout to fit the extension when the mag tube cap is screwed down! The only guns that I know of that have any locking recess directly in the receiver are the guns where the barrel is threaded into the receiver and isnt a quick take-down type of barrel. Example is the High Standard flite king. In almost every respect the Mossberg is based on the flite king, but the difference lies in the flite king having only one slide bar, the barrel being threaded into the receiver on flite king and therefore the bolt locks into a notch in the steel receiver itself and not a barrel extension, and finally the lifter rear pins don't project through the sides of the receiver. I don't know if any high standards have ever suffered from lifter jam with pins coming out of their location but apparently it happens with mossbergs sometimes. I don't think it has anything to do with the fact that the pins are seen in the holes through the receiver on the mossberg. It could be the fit is tigher in the flite king so even with a drop the lifter rear pins stay in place. Dissasemly is almost the same for 500 and flightking practically. The 500 is based on the high standard flight king, and the high standard is based on the Remington model 31, in turn the 31 is based on the Browning designed Remington model 1917, which was almost directly copied by the more famous and improved Ithaca 37. Both the Ithaca and Model 31 Remington are improvements on the model 1917, but while the model 31 is not as sexy as the Ithaca 37, the 31 is actually the better gun. The High Standards are very attractive short receiver guns that have skyrocketed these last few internet gun-forum years! The high standard k210 riot gun used to be a sleeper of a gun purchase but now everyone knows about them. They are cool in being a factory 6 shot with a very cool and sexy way the mag tube is attached under the barrel, combined with the sleek little receiver, these are hot little home defense shotguns, and well beat-up old used police guns sell easily for $850! They are great hunting shotguns to especially the 16ga, but you have to not mind the heavy weight! Most upland hunters want a light aluminum receiver semiauto or slim and light sxs. However if weight and balance isnt a big issue and you put a lot of practice with a flight king, they are a fairly reliable hunting pump as long as interuptor parts aren't worn and channels clean you won't suffer double feed tube jams, it can happen to dirty or damaged mossbergs and 870s as well. Honestly the Winchester 1897 looks to have the least chance of double feed!

1st animation mishap - the animation is correct your measurements or dimensions are incorrect either for the bolt or the locking block one or the other is incorrect. 2nd animation mishap - yep your correct 3rd mishap - yep your correct.

Hammer spring is better on 870. The mossberg hammer spring is held in by a pin at the rear. That pin walks out and releases much of the spring pressure, and so creates light strike and failure to fire. Fix is something to keep pin held in place. Also lately Mossberg has supper heavy firing pin return springs inside bolt! No reason for that, and either send in to Mossberg to replace, or buy a lighter replacement spring, or cut a coil or two off that spring! Two really bad flaws that could potentially cause missfire in Mossberg 500! The lifter design is actually better from the sense of smoothly and directly chambering a round on the Mossberg vs the high up angle required of lifter to feed rounds in the 870. Many times with the 870, a round will bounce its front edge on the barrel extension edge and you'll feel it, and sometimes if you were slow racking forward you will have it catch and stick, and you have to slightly go back a tad, and then forward again! This is especially true when pumping and aiming up at a decent angle at a high clay! Its not a big deal, usually avoided by making sure that slide is moving at a normal fast rate with no rearward pause. The Mossberg 500 has no issues like this, its very smooth cycling because the lifter is inline with the chamber when up and round is right inline therefore with the chamber as well! Also its out of the way for loading the mag which is nice. The parts also are much easier to replace on the mossberg and the 870 requires a gunsmith to re-stake ejector, or interuptors if they get damaged. If it bugs you, you basically want to touch up the newly replaced ejector because the pins for it are exposed on the left side of the 870! Id say leave it be or paint them or blue them to match. The mossberg ejector spits empties out nice and far to vs the 870! The 870 even with fast shuck, the ejector seems weak, the emptys clear but they don't fly that far. They spin a lot and have hangtime near the receiver before falling to the ground. Overall the 870 is a bit clunkier in function and more a pain to fix. The 500 potential failure to fire however is a bigger issue to me. Some say the mossberg 500 slide bar block likes to unweld from the slide tube more frequently than the 870, but I'm not sure of that, I think they are equally susceptible to welds coming loose and its rare. Its possible because the 500 slide bar assembly has a separate block from the bars that is welded to the slide tube, the bars being pinned to that block, that possibly heat doesnt flow evenly away from the weld, whereas the 870 the slide bars are a 1 piece long strip of metal that wraps around the slide tube and welded there, maybe the heat is more evenly distributed through the the entire length, therefore that weld might be a little more consistent and better weld. Doesnt really make sense though, metal slide tube mossbergs are predominant in the Army and Marines! I think slide tube separation is extremely rare in the military and those 500s and 590s are used hard!!! The 870s in service also are old and well used and still working fine, particularly the old heavy bayonet block fitted Marine corps 870s. Though seeming cheaply made, the pinned slide bar plastic forend of the Maverick 88 likely is better than having a metal internal slide tube because it eliminates the need to weld the bars to anything!

So? Just to be clear, the timing is off on the movements of this animation? My GOD! Between your nasally, whiny voice and the repetitive bashing of the animation, I wanted to go kick my dog! And I love my dog. Dude, if the animation sucked so badly that you had to drone on about “the timing”, why the hell didn’t you make your own perfect animation? We get it. It’s not perfect. Seriously, brother. That was painful to listen to the entire video. It’s a full of a good break down of the individual functions but......👍🏻🇺🇸
