I have a Troy Defense Carbine. Aluminum mags lock up fine in it as do M3 20rnd Pmags. But my earlier 30rnd PMAG M2's don't nor do (of all things) Troy Battle mags. They just don't lock in even with a good rap to the underside of the mag. If you drop the lower from the upper, same difference. Does this sound like the mag catch needs to be adjusted? Sorry for the noob question. I could swear these other mags used to lock in but perhaps they didn't (I haven't had a chance to shoot it yet). I didn't notice it until after getting the 20rnd PMags which did have to be rapped on the underside a bit at first to get them to lock (they do now)
I'm not sending the rifle back to Troy as I have heard of the time it's taking for those with magwell issues to get their guns back - besides mine doesn't have that particular issue (tight magwell) all mags fit in fine and drop free - they just don't all lock. Worst case, I'll just stick with aluminum GI mags and later PMags but I'm wondering if it might just be that the mag catch needs to be adjusted by someone that knows a bit more about these things than me. Thanks, Earl |

Yep, found the example on youtube (youtube is your friend). Unfortunately it still didn't fix the problem. I guess next I'll try another mag catch and see if that fixes it. If not, I'll just stick with later PMags and USGI.

Ok, I'll look for some noob instructions on how to do that..I'm assuming the bolt release has to be removed? Earl Nope, just need to push the mag release button in so you have enough room to rotate the mag catch. |

Could be but I think most of those people had drop free issues, all mags drop free with this one...problem is I don't want some of them to drop free when theya ren't supposed to! :)
I've heard of others having the problem because the "tab" or whatever you want to cal it on the mag catch doesn't quite engage enough in some mags...that feels more like the issue with this gun...another mag catch might resolve it so I'll try that first. Ear Quoted:
I seem to remember multiple accounts of Troy rifles having a tight magazine well. This may be playing into your problem. |

Gotcha, I guess I misread the problem you were having.
Here is an in stock magazine catch that won't break you on shipping. http://www.thecitizensarmory.com/Magazine-Catch_p_38.html |
| With the upper off, look down the magwell from the top as you're inserting the mag up all the way. What happens when the mag reaches the tab from the mag catch that's supposed to get inserted in to the magazine? I'm guessing its not inserting in but why? Does it ride over the hole? Is it not lined up and it just missed it all together? Compare what you see with a mag that does lock in. You may just have to enlarge the hole on the side of the mag a little. I would replace the mag catch first as stated above before you go modifying mags. |

The important part of the catch is the part that sticks through the slot and actually sits in the magazine's notch to hold it. It should be very square and uniform. If the catch is not square, it could present a tiny bevel to the retention slot on a plastic mag, which could help prevent it from staying snug. Since mag catches are inexpensive and available, that is the first thing I would think about doing, since tightening it didn't help.
(I'm assuming that you didn't just tighten it one turn...you can use a punch or cleaning rod section to push the button in a LONG way, so it is actually possible to tighten the catch TOO much and even prevent inserting a magazine at all...) |

Nope I didn't just tighten it one turn...tightened it a couple of turns to where it was no longer flush with the button but protruding out a bit...still didn't lock. I did replace the mag catch, still didn't lock on the other PMags and the Troys. Hence why I sold them. It locks fine on every aluminum and steel mag so I'm just going to go with those. One of these days, I'll send it in to Troy but not until after it doesn't take 1-2 months to get the gun back.

No, all mags have been unloaded while trying to get them to lock into place. The Pmags and Troys just won't stay locked. It sounds like they lock sometimes - but you can pull them out or if you cycle the bolt it will be able to be pulled right out or just drop on it's own sometimes. Something is probably a tad out of spec in the magwell..like someone said I could probably get things to work if I dinked iwth the mag hole in the mags...but I'll just go with USGI aluminum mags for now. It isn't like I had a pile of PMags and Troy mags...kind of funny though that it comes with a certificate that Steven Troy himself inspected the gun...uhhuh.... (must of used an aluminum USGI mag).

The magazine catch doesn't have anything to do with your problem if standard GI magazines lock in fine.
The problem is your P-Mags. If you looks at the front of the P-Mags, you'll see a ridge, that can contact the front of the magwell on the lower receiver. This can limit how far the P-Mags can be inserted into the magwell on the lower receiver, which is then limited by the bevel machined on the magwell edges by the manufacturer of the lower receiver. GI magazines don't have ridges on any of the four sides that could interfere with the magazine being fully inserted. The magazine catch controls how far the magazine inserts (other than the bottom of the BCG). The treatment of the magwell edges on lowers is one of the only places where you will see a lot of variation from manufacturer to manufacturer. When I went shopping for additional lower receivers, the magwell was one of the features that I paid careful attention to. The heavy bevel on all four sides of the magwell of JD Machine Lowers is one of the reasons I went with JD Machine. I don't remember if it was on this website or another, but a Member posted photos of how he filed the ridge on the front of his P-Mags to allow them to lock in on his AR. |
