Hey everyone, I was looking to get an upper from BCM:
http://www.bravocompanyusa.com/BCM-BFH-16-Mid-Length-Upper-Receiver-Group-p/bcm-urg-mid-16%20bfh.htm I was wondering, in the future I wanted to make it a flat top without a FSP (once I save up some cash for a eotech or aimpoint). Is it difficult to change a FSP out and put in a low profile gas block? What tools would I need? Any and all help is greatly appreciated! Thankyou! |

Worst part is removing the damn taper pins from the FSB. You will need a good support for the FSB to lay on, a ball peen hammer, and a brass punch. And the will to whack it pretty good to loosen the pins.
There is, somewhere in this section, a tutorial about all that. Might even be a thread; search for it. P. |

Dremel the FSB off. Since they are mated to the barrel and drilled on a jig, they are almost never reusable. If you do attempt to get the pins out, use a real taper pin starter so you don't flatten the heads out and frustrate yourself.
I like grinding mine off with an angle grinder to fit under a TRX or quad rail setup anyway. |
