How hard is to change one out and what tools would i need besides pliers and pouches
thanks |

Not sure why you'd be using pliers or pouches.
Sturdy table steel hammer GOOD punches The delrin block sold by Brownells (or midway?) is pretty helpful too. Start with an oversized punch to get the pins moving, then move to the smaller ones to tap it out the rest of the way (once you get the pin moving with the oversized punch, the pins move easily). You likely have taper pins, so pay attention to which side is the small side. Hit it on the smaller diameter side to remove. |

What brand of upper? The taper pins on some brands are known to be insanely stubborn. Your best bet is to send it off to a qualified smith... and save time, money and frustration. I learned the hard way. Just use a large punch and heavy hammer/ mallet to get it moving, once it moves switch to a smaller punch. Be sure to support the barrel and gas block, then knock the living hell out of it. They are tight most of the time, so you cannot baby it. |

Im the type of personality that would rather do something my self when it comes to my rifles or pistols, or car, or truck, or tractor, or, well you get the picture.
Changing out a gas block is pretty easy, IF you have the right tools, a good hammer and good punches are a must! I took a 2X4 about 8 inches long and used a drill press to make assorted sized holes to use as a block, works well enough. I'd say give it a try, if you cant get it then go pay a 'smith. Good luck Rob |

I learned the hard way. I bought a DSA barrel, and when it arrived it had a front sight tower on it. I read up on the proper way to remove it and used all the right tools (contoured wood block instead of brownells tool) and proceeded to beat the hell out of the pins and they wouldn't budge. I did eventually get them out but destroyed the pins in the process. Learned that DSA does not use tapered pins, instead they crush fit straight pins. |
