Bullet button or MM grip

[railroader]

I finally am going to get around to building an off list ar. I'm up in air if I want to go with the bullet button or the MM grip. If I go with the BB and I change my mind I'm I going to be able to remove it without jacking up the receiver. I already have pre ban mags so that's why I'm also thinking about the MM grip. So has anybody taken out a BB. Mark

I started with a Prince50, went to the BB, and ended up with the MMG. BB is easy to remove, but save yourself some time/money and just start off with the MMG or U15

Get the newest version of the BB and it will be a piece of cake. It's a drop-in version that requires no filing. 10% Firearms has them.

The BB vs. MMG is really a personal choice and depends upon the use of the firearm. Fun range toy? That's what a BB is for. Real world use? Get a MMG or U-15.

You'll probably want one of each.

Remember, with the MMG and U-15 you can't have any other evil features (flash hider, collapsible stock, etc).

BB 1 requires filing?

BB 1 requires filing?

yes on the outer sleeve,then you just tap it in with a mallet.should be a sung fit,dont file too much or it`ll be loose in your receiver.

There's nothing wrong with it being loose. That was a precaution from back in the day. The newest version is drop-in.

I vote MMG/muzzle brake/fixed stock/etc without reservation. It feels surprisingly good (especially if you're not already used to the pistol grip), and you'll be able to use your preban magazines.

I've never tried a BB, but the idea of using a tool to drop mags, however convenient, just doesn't sit well with me. I might try it on my second build sometime in the future, though.

Well looks like I'll not only be exchanging that LMT upper but also exchanging my BB1 for a BB2.

Keep in mind the BB2 is also shorter than the BB1.

I now have nothing but he new BB I that drops in and requires no hammering.

My first question in response to this question is do you have any large capacity magazines that you purchased before 2000? If you do, you might want to go with a MMG build as featureless is the only way you can lawfully use those magazines in the State of California.

If you do not have any large capacity magazines, then I might recommend you start with a BB I build since you are going to be limited to ten rounds anyway, why not retain the evil features (which become good-hearted once you have a fixed magazine)?

In the end, you should have a receiver with both set ups. That really is the only way.

I went with MMG knowing I can change to pistol grip very quickly as needed.

I already have pre 2000 20 and 30 round mags for my keltec su 16, and I have a couple of 10 rounders too. I guess my main problem is I really haven't been around ar type rifles so I'm not familiar with them at all and I'm looking for something that is easily reversible. So how exactly is the bullet button held in? Is it friction fit, thats why people tap them in snug? Sorry for all the questions but I like to dwell on things. Mark

if you already have hi-caps. i'd say MMG all the way!

i do not have a bb "yet" but when funds permit i plan to get one. so this is only what ive heard and not personal experiance, so keep im mind that i may be wrong.

the first bb had to be filed to fit snug for ensuring it cant be removed easily. that was back when there was a question about what fixed mag meant and questions about how permanent the alteration must be. now that we have progressed and cleared up things we know that having a drop in part that is able to be removed is fine. so now the new bb works without having to be hammered in and it can be removed with a tool.

This is the bullet button frame (Versions 1 and 2, note the "edge" on 1 that you should file down until it drops in):


This is how the BB looks installed:



The bullet button frame drops in. Then you install the mag catch for the AR (standard part). You put a spring around the catch inside the BB frame. Lastly, you tighten the center nut that screws onto the mag catch (inside the BB frame).

In the end, you have hi-caps. You should get a MMG or U-15.
