AR-15 magazine catch/release button problem

[BBSparkle]

I picked up an RGuns lower from Bradis this past weekend and went to install my magazine catch when lo and behold, the button won't even fit.

I suppose my question is: Is it okay to get a file or something to open this hole up some? Or should I see if I can get an exchange on the lower itself? Finally, I suppose I could try another button, but I don't want to have to buy an all new LPK to get one.

Any help would be appreciated, really want a quick fix so I can get out shooting during the nice weather tomorrow.

I would contact Bradis first, to see if they have a remedy for this. Then contact the manufacturer. You could try another release button, I have seen several LPK's that had parts not fit correctly. Only modify the lower as a last resort..

What kind of parts kit do you have? We had some Bushmaster LPKs with the plastic mag catch buttons that were too large to fit the RGUNS lowers, but the ones provided with DPMS and Daniel Defense LPKs dropped right in.

I have the Del-Ton parts kit that came with my whole rifle kit I ordered from them.

I would modify the button prior to modifying the lower.

I would modify the button, but it IS plastic, and I'm unsure of how to do so without breaking it/having it break inside the lower.

First/best option for a quick fix is to file the mag catch button to fit. Use coarse sandpaper or a Dremel tool on low speed, and go slowly, removing only as much material from the edges as needed to allow the button to fit.

When the shop re-opens on January 2, you're welcome to call and I can check our parts bin to see if we have a spare mag catch button that might work on a more permanent basis.

Alternatively, you could just order the required part from PK or Brownells, and have it in a couple days.

Thanks a lot for the opinions, guys. I think I'm gonna go ahead and sand it down for the weekend and pick up a new button next week.

Glad I didn't just hop straight into filing the lower. Seems stupid now that I think about it...

Me too!

Sometimes when one part is at one end of the spec and another part is at the other end, they might not fit together quite the way they should. Neither part is "out of spec," but that's little comfort in the midst of a frustrating build. BTDT.

Just to rule some things out, do you have another lower you can try your Del-Ton mag catch button in?

No. Not yet, at least.. But for $3 a piece, I don't mind sanding it. And we'll see how the new one fits next week. Honestly, I suppose I'd rather have an aluminum button, anyway.

If we don't have any buttons in-stock, I need to do a parts order next week anyhow and would be happy to add one on for you.

 

[BBSparkle]

That would be great, I have a few things I need to pick up from you guys, anyway.

Update:

We do have a DPMS metal mag catch button in-stock; I tried it in one of our RGUNS lowers today and it dropped in fine. I have a couple more coming on my next parts order, as well.
