| Any tips on installing a gas tube into the FSB/gas block without bending the tube or hurting myself? I have a PRI flip-up front sight/gas block that the gas tube hole is very tight. I feel like I will need a hammer or pliers to get the gas tube in, and I want to check if there are any tricks to this step before I screw up a $13 gas tube. Thanks. |
| Did you already mount/pin the gas tube in the FSB, and can't get the tube into the upper receiver now? One option is to separate the two - gas tube and FSB/gas block. Mount the gas block on the barrel, slide the receiver-end of the gas tube into the upper as far as necessary to clear the gas block, then bring the gas tube forward to the gas tube and insert it/pin it. Sometimes, that's the only way to get it done with a lo-pro gas block, so maybe that'll help in your case. |
| Thanks for the replies. The gas tube is very tight going in to the gas block. I would need to pound it in with a hammer, and then wouldn't be able to get it out without damaging it. The gas tube is a DPMS tube, going into a PRI flip up front sight/gas block. It goes into the upper receiver just fine, but not far enough into the gas block to put the roll pin through. |
| I finally got it to install easily. I ended up taking some coarse sandpaper to the end of the gas tube and sanding it by hand with a bit of gun oil. Got it down to a size where it would go into the gas block with a bit of twisting easily. All is well with the world/my build, and it is now sending lead downrange without trouble. Thanks for the tips. |
