    This is a good video on the basics of installing, but it doesn't cover the gas block hole to barrel hole alignment. If the gas block you are installing happens to index perfectly against the hand guard piece or quad rail, that's great, but that's not always going to be the case. I'd like to see a video on how to do that alignment.

    Great video -- how do you plan on installing the handguard ? Take everything apart and do it all over again ....

    im sorry but i have to say it, while your video quality is not as high as a competitors videos... the information given is much higher quality, longer length,more indepth and is not just to sell a product. infact i have noticed its very rare that someone will say "you can buy this part from us" with every tiny tool because its obvious where the items came from!!!. you are trying to help customers who are not gunsmiths by trade. for that i applaud you brownells even if i have never ordered anything from either you or your competitor. well not yet anyways and i know who i will be picking :) happy holidays brownells staff.

    We used to use china markers to draw on set lines so we new the gas ports were lined up but it added extra time to a relatively simple thing

  • @pman5k4u
    @pman5k4u 11 лет назад

    Also many gas blocks of the low profile design have a set screw directly beneath the gas port. Many barrels also come with a indent for said set screw. For other types, such as clamp on, measuring and witness marks is the best thing.

    That’s funny.. I’m actually looking to remove the modular gas block and replace it with a A2 front sight gas block. I guess I’ll watch the video backwards! :)

  • @Pohlville2

    should you loctite the allan keys on the bottom of the gas block and what keeps it from rotating around the barrel? thanks

  • @jamesws3
    @jamesws3 11 лет назад +2

    Why no dimpling for the set screws? From what I understand dimpling makes the block MUCH more secure and is specifically recommended by Larue, etc.

  • @quiggs8361
    @quiggs8361 2 года назад

    So I changed up an m16a4 upper to a low profile gas block (well my gunsmith did) but now I have this small little section of barrel that is in the white showing, that the new gas system doesn’t cover up, I was wondering if there was a way to re-finish over that small section or, if there was anything I could do, really, to not have this shiny ring 3/4 way down my barrel! Lol

      There are oils that when you prelube those pins that they do indeed come out that easy sewing machine oil is a very good example of an oil that will seap into the pin holes to allow for lubration of the pins after a few minutes

    Excellent! Just what I needed. Thank you. Are the gas blocks standardized height?

    • @jamesdewer
      @jamesdewer 4 года назад +1

      No they are not. The exchange of two unknowns. Installing a gas block requires a significant teardown of your upper. By profession I am a Naval Gun Engineer. IMO you're better off learning to hand load and tailor rounds to fit your rifle. It's the reason Companies don't for example, include adjustable blocks. Keep what you got. I know SCAR come with the adjustable blocks but you must realize your introducing more variables into what's now more unknowns.

    • @crabblike

    I'm considering doing this to my rifle for a front sight.

  • @MS-pp3mz
    @MS-pp3mz 8 лет назад

    I hope this doesnt sound like a stupid question but with that front site, i have a 300 blackout and the gas block is already set up and to be honest i dont want to mess with it just wanted to add that style front site, is it possible to add that without messing with the gas system?

  • @biglee6674

      For the gas block set screws, we suggest using 272 Red Loctite but be aware if you need to remove the screws you will have to heat the gas block up with a propane or MAPP gas torch to remove the screws.

    • @rubiconnn
      @rubiconnn 10 лет назад

      The gas block takes the pressure from the barrel when the bullet is flying down it and sends the pressure down the gas tube to push the bolt back and eject the shell and load a new round. Technically you can shoot without one, but shit will fly upwards out of the port in the barrel and you will have to manually pull the charging handle after each shot.

      @@richbradley9043 No problem. Just stick the straw inside the gas tube from the receiver end (make sure its inside the tube) and your other hand or someone else with their hand at the muzzle end. You should feel a good bit of air while you do it coming our of the muzzle end. You could also use a post it not or piece of tape at the muzzle end. Good luck chief...

      especially with low gas blocks available to cheap if you know where to look.
      and a take off triangle sight block costs more than one of the low-pro blocks. so could recoup most of your money.
