Really nice...
Machined really nice. It does stick out a bit more then the standard mag release button, but I think that was purposely done to make it easier to find in quick situations. The knurled surface on the oversize pancake button is machined really nicely. No dings or any of the knurling smashed down. Screws on and embeds into lower cavity of magwell really nicely as well. Not tight at all, but not really any slop either. Hole drilled and tapped on oversize button is great, as when botling down, threading didnt catch or stick, which usually means it was a bad machinist job. No, this was pretty smooth. Just as a note, this works well with the Norgon ambi-catch sold here on Brownells. I bought both for my ar, fits up beautifully. I wouldn't hesitate to put on another ar in the near future I build. Actually, would be one of the first parts I buy in accessories.
Nice part
This is much bigger and easier to use than the stock mag release. I like the fact that it sticks out further than the stock release; it's location feels very natural and intuitive. This works really well in conjunction with the Magppul B.A.D. as well. It is also a nicely made, high quality part. You will have to definitely remove the bolt catch to install this correctly, but that's only a minor pain for such a useful upgrade.
Just what I needed !
I bought a new R15 rifle in 204 cal. and I didn't notice that the magazine release button didn't work. I took it apart and found it was defective, so I ordered one of these, it got to my home in a few days, simple to install took about 5 min. Better than the Factory release button. Thank You Brownells !
Should come with o-ring
I have several of these and they all have an o ring snapped over them to set under the button. This keeps the operator from depressing button to the point that the mag catch falls out and allows installation without removing the bolt catch. All you have to do is seperate your upper and lower and rock bolt catch back and forth as the latch moves over it the last few rotations, once mag catch is in place snap o-ring over button. Problem solved.
Great product
Like others, i agree machined real nice. Feels good looks good. Sticks out far enough that during mag changes the weight of the rifle is enough to engage the button. The spring weight seems a bit stronger than my original aswell. You will have to remove the bolt catch though, and for that reason i give it 4star rating.
BIG BIG BIG mag release
I ordered these for two rifle builds. Good quality and finish but are HUGE, I think very ugly also. I am ordering another kind since these are very large and stick out very far from the reciever. Just beware they are VERY LARGE!
Must install carefully
Nice large button. Comes with new spring. Requires removal of bolt catch to install (pain) to screw magazine catch far enough into release button to prevent the mag catch arm from over-extending and rotating. If you don't, you can depress the mag release button too far and the mag catch rotates down (bad in a fire fight, your next mag will just fall out...)
Half done
Bought this extended button hoping to get more thread engagement in an AR10 lower. Even trimmed side of button to clear raised rib. You cannot thread the button on far enough to keep the mag release from falling out of it's slot when the button is depressed. If this item was 2 piece I would give it 5 stars but it is not so 3 stars it is. Very well made. No I do not recommend. Krusty
Emphasis on Extended!
High quality part. The button head is about twice the size of the stock release. What I didn't plan on was the length of the extension, which is also about twice as "high" as the stock release (3/8" from receiver). This is fine for target shooting or competition...but... as a lefty, when I carry the rifle muzzle down with a two-point sling, the button either stick me in the chest or makes significant contact with a tactical vest and mag pouches. This results in a moderate chance of accidentally dropping the magazine, which makes it a buzz-kill for tactical use.
