[ARCHIVED THREAD] - Mags won't seat when bolt closed (Page 1 of 2)
Posted: 1/18/2015 3:06:43 PM EDT

First off I've read a dozen threads about this so I'll go over what I've done. I've got a BCM Ricci 16" rifle and when the bolt is closed the mags need some serious force to get them seated. So much it severely dents the cartridge on top of the mag. I'm a very big, strong dude and I have no doube the force is enough to break the mags and other people simply can't seat the mags.
1. Both Magpul and Steel mags have been tested 2. It doesn't matter if they are loaded with 5 rounds or 30 3. I've had the mag catch as loose and tight as possible with no difference It seems to be 100% the bolt, I took the bolt out and the mags seated fine with no issue. Is this an issue I or BCM can correct or something I just have to live with? |
I have no problems seating mags, and this is how much PMags sit above where the lower meets the upper. Separate the lower, and compare yours with the picture below. Notice the bullet pictogram with 5.56 x 45 written within it, and how the lower dissects the bullet point in half of the pictogram.

Unfortunately nobody I know owns an AR so I can't switch out the BCG |

How many rounds are you loading in those mags where seating them on a closed bolt dents the cartridge? It's usually a bit tight seating on a closed bolt. Quoted:

With 5 rounds in the mag, the rounds will be pushed below the feedlips so under no circumstance should that dent the casings. That wouldn't be the upper... that would be a mag issue but you say it does this with multiple mags so ??? . Are you making sure you are seating the rounds all the way back in the mag or is it possible that the tip of the projectile is catching on the front of the mag preventing it from receding into the body of the mag upon insertion? From an open bolt, once you insert the mag, will it feed a round and cycle? And you are the only person you know that owns an AR... wonderful  . I honestly don't think it is your upper man. It sounds like your mag is inserting too far into the receiver causing the feedlips to contact the bolt before the mag catch can engage... look at the pic above (and below) and see how far yours goes. You have a LGS that has ARs?

I would like to see that happen.

It only dents the cartidge when it's loaded to 30 or 29. Any less than that doesn't dent the cartridge, but it feels just as hard to load it. For example, I have to turn the rifle on it's back against my knee, I insert the mag, and have to hit it with all my weight to get it to go in. I don't see any marks of wear on the mags themselves, and they load fine without the BCG in the rifle. They also feed fine as I typically load the mags with the bolt open and I havn't had a single malfunction, 500 rounds through the rifle (Tested all 9 of my mags) |

First off, I would STOP what you're doing with using excessive force to insert a mag.
Something is obviously wrong and you're not going to identify or correct it by using excessive force. Could be any number of things, from a bolt catch a little too large, to an upper or lower receiver machined out of spec or some odd tolerance stacking issue. The best option for troubleshooting at this point would be swapping upper and lower halves from another AR15 type rifle to see if you can narrow down where the problem is coming from. |

Stop forcing in the mags before you break something. See if your LGS will let you swap out uppers and lowers. |

I think he likely meant if he uses a 5 round mag with 5 rounds not a pmag with 5 rounds in it. If that is what he means then there is some voodoo going on because there is no reason spring tension would be strong enough.
OP I would bet you are loading 31 rounds instead of 30. Try downloading the mag a bit and see if that helps. Also take a picture of the round on top as it appears in the magazine. |

There's your problem! I keed! I keed! One question that hasn't yet been asked: what brand of ammo, bullet weight, cartridge OAL? Factory or reloads? Some types of ammo (match 75+ grain) are near the max (or in some cases with very low drag [VLD] bullets, exceed) OAL for a standard AR mag. Perhaps the OAL of some of the cartridges are causing binding near the bottom of the magazine. |

Pictures are worth a thousand words. Pic of lower with mag inserted, pic of mag taken through ejection port, pic of damaged round, pic of bottom of BCG.
If your lower with a Pmag inserted actually looks like the two above then the problem would likely be in the upper or at least it's not a gross defect. Since mags insert fine with the bolt open, and being downloaded makes no difference then it has to be the body contacting the carrier, however if the body were contacting the carrier hard it would not run 100%. Something doesn't add up. If your comfortable with it post up your state, maybe someone is near you and willing to take a look or let you try another BCG or upper. |

It is always more difficult to seat a loaded mag on a closed bolt. +1 So stop doing it already. Always lock mags on an open bolt. What you are doing is abuse. When you abuse a gun, it usually will find a way to return the favor, which frequently doesn't go that well for the operator. Now I'm not saying that something isn't wrong or that it can't be fixed. I'm just saying we can't zero in on what is wrong from here. So, to keep using the rifle until such time as an answer appears, just lock on the open bolt. Evidently builds go this way sometimes. I'm inclined to think 'tolerance stacking' comes into play. But even on a perfect set-up, there is very little play left in a loaded mag and the operator will frequently encounter resistance to mag lock in the 'tactical reload' where the rifle is loaded and the previous mag, which may or may not contain ammo, is dropped and a loaded mag locked against the closed bolt. Unless you are practicing the 'tactical reload', there is no need to ever lock a loaded mag against the bolt. |

I've had difficulty seating fully loaded mags before, but not that bad. It was usually a matter of finessing it instead of forcing it. Loading mags all the way can cause feed problems. I'd only load them to 25-26. Maybe try that? If loading your mags to 30 rounds causes feeding problems, then something is wrong with your rifle. |
|
If all magazines do this, different brands included, something is off with your lower or the mag-catch.
I would mic the distance from the top of the magazine catch inside the magazine well to the top of the receiver and compare against a known good lower. If this is what is 'off', look to see if the catch is thicker or the hole in the reciever is too high. If it is only a few thousandths off, you can sand/file the top of the catch carefully. This will relieve a tiny bit of pressure off the seating effort. Be very meticulous in doing this, as even a couple thousands can make a big difference. Regards |

Regards Couple thousandths making a difference here? No. Hell the tolerance spec is probably 5 thousandths. If you are truly denting ammo, on a 30 round magazine, with ONLY 30 rounds in it, and still failing to seat on a closed bolt, then something is WAY wrong with your magazine, or something is terribly out of spec (to the tune of more than 20 or 30 thousandths or more) with the upper receiver, lower receiver, mag catch, or bolt carrier. The ammunition hits the bottom of the bolt carrier when seating on a closed bolt. This pushes the ammo down into the magazine little to allow for full insertion of the magazine up to the catch. There is a little room in all milspec 30 round mags to accommodate for this, and a LOT of room in all PMAGS (which sometimes allows people to put 31 rounds in the mag without realizing this) SOME people downloaded to 28, for the purposes of creating more room for the ammo to move, to ease a close bolt magazine change. |

They also said it compressed the springs too far and might cause trouble feeding. |

You can have feed problems if your mag is filled to capacity regardless of whether you load with bolt open or closed, but that's the perpetual discussion.
OP here says he can't load regardless of number of rounds in the mag, so there's obviously some other problem in play. |
|
I've had it happen with Pmags. I believe it is fairly common with them
(I even heard once that pmags weren't designed to be inserted on a closed bolt [grain of salt]) if the rifle operates properly otherwise and there are no feeding issues when installing mags on an open bolt, then just do it that way. (provided your bolt is locking back on an empty mag every time, that would be the proper procedure for reloading anyway) |

This is how I fixed my P-Mags and Steel, Aluminum mags with Magpul Followers.... be advised though, after doing this, if you drop a fully loaded mag, the first round ( Or 2 more ) will more then likely "pop" out
I also prefer not to have to force my mag changes... my alterations , resulted in easy to insert mags. The alteration allows the follower to compress slightly more when you insert it. Disassemble the magazines. Do one magazine follower first to see if this helps. Put on your safety glasses..... On the P-Mag, disconnect the anti-tilt follower, and look at the general shape of the bottom of the "legs"...( you should re-contour the altered legs ) you will want to remove about an 1/8 to 3/16 of material from both legs. I mark how much I want to remove with a permanent marker. I use a die grinder with a coarse grinder wheel. That will remove a lot of material fast. The fast grinding action melts the take off material, that makes it very easy to clean up. The melted part will snap right off. You can also use a belt sander... but this is slower....material removal doesn't need to be a work of art, so don't bother to clean it up excessively. I then re-contour the bottom of the legs with smooth edges, again it just needs to smooth-ish... not perfect. Re-assemble.... test. You should immediately see a difference. You can do the exact same thing with any mag with a Magpul follower. The current production Lancer mags .... you need to disassemble the mag , remove the floor plate... then remove the locking base plate from the spring. The "block" that stands proud on the locking base plate needs to be shorter.... Safety Glasses on.... Grind of about an 1/8- 3/16, making it shorter. Remove the excess melted plastic... re-assemble. Test. AGAIN... the shorter "legs" allow the bullets more room to depress in the mags.... so if you drop a full mag on its base... you can expect rounds to pop out. That IMHO is not that critical to me...A Fast easy mag change is. BTW, my rifle that prompted me to do this is a BCM EAG, I suspect they ( BCM ) just uses tight fitting parts... My PSA Uppers ( looser fitting ) don't have this issue. Worst outcome from altering your Magpul follower..... you get to buy 1 new one. |

That right there says the follower cannot depress anymore... my advice is the cheapest way to offer a possible solution , that is why I suggested it. Any and all altered magazines I have done this to... function just fine. Bfoo, you are right on. Ignore the haters as they just love to hate and not offer help.. The superiority complex in play.. |

You say what you like but I will take the advice from someone who has been outside the wire over someone on the internet. Of the 5 instructors 3 have been in combat. But then again if its on the internet it must be true.

Well I'm not going to go far enough to say it's "derp," but when doing a 4-day carbine course I and the guy next to me were having this exact problem doing "tactical reloads." Slamming the mag in and slapping it failed every time. Smoothly inserting it and exerting a normal amount of pressure worked almost every time. I don't slam them anymore now and haven't had problems since. YMMV. |

If your rifle doesn't work with a number of known good manufacture mags, there's a problem with the rifle. There's no way I would bother dicking around with every single one of my magazines so it works in a rifle. That would take weeks. Fix or replace the rifle.

I'll have to try it. Frankly,I was told it was "bad practice" when training at Front Sight (before I owned an AR) and just never tried it. They also said it compressed the springs too far and might cause trouble feeding. Quoted:

I've had difficulty seating fully loaded mags before, but not that bad. It was usually a matter of finessing it instead of forcing it. Loading mags all the way can cause feed problems. I'd only load them to 25-26. Maybe try that? If loading your mags to 30 rounds causes feeding problems, then something is wrong with your rifle. This. I have D&H 30s, NHMTG 20s, and PMAG 30s and 20s. All will seat on a closed bolt when loaded to full capacity. I'll have to try it. Frankly,I was told it was "bad practice" when training at Front Sight (before I owned an AR) and just never tried it. They also said it compressed the springs too far and might cause trouble feeding. I wouldn't return there. Think about it. Why are mags designed to hold 30 rounds if loading them to capacity is "bad practice?" Those instructors don't know what they are talking about. |

But being a rank newbie...I just swallowed it and moved on. |

I have never heard of this problem or experienced it myself but if i had to trouble shoot this problem i would put orange or yellow acrylic paint on the bullet and case (completely covering it) that rests on the very top of the mag when fully loaded. Insert the mag completely then remove. Look for any abrasions on the case and projectile and also look inside the rifle. See of you can detect anyplace where the paint is being rubbed off.
If that doesn't work, paint the completely paint the upper portion of a mag (the part that inserts into the receiver) and insert again fully loaded. Again, remove and look for any paint that has rubbed off. IDK if this will work but it may help you detect what is out-of-spec. Good Luck |

OP left the building on the eighteenth.
He also said the mags were extremely hard to insert even not topped off with the bolt closed. So while the damage to the rounds when topped off may be a clue, clearly it's not his whole problem. Also he said damage occurs at 29 or 30 rounds loaded so either it is a major defect, as in a protrusion larger than a cartridge case diameter (hard to envision the BCG cycling like that), or he's not counting accurately, not counting accurately with PMAGs has led more than one person to cramming a 31st round in, and they are an absolute nightmare to seat at that point and I could maybe see damage occurring if you could generate the force required. But still this is not the whole problem. |
