PTR 91 bullet button question.

[Eddie1965]

I recently purchased a steel lower for my PTR 91 (http://www.robertrtg.com/store/pc/HK...ES-40p3007.htm) and when I tried to install it I noticed that the bullet button that came with my rifle (Radlock) does not fit with this lower.

Do I have to switch to a different type of bullet button? And if so, which one do you prefer?

Thanks

If it looks like this one posted in another PTR thread then it should work with the metal housing or at least it works on mine:

Just like this. It is only a cover, all the metal parts for the release are held by the upper receiver and will take quite some disassembly to remove. If you are converting to a metal lower, you will most likely end up having to trim it to fit over this little plastic piece and hold it in place.

The Prince 50 bullet button is hands-down the best.

That plastic BB is absolute garbage. The price 50 BB is all steel and will work with any lower. Hands down its the best one for HK style rifles.
