SW M&P10 Gas Block/Tube Removal Problems - Help!

[lshel]

I'm was installing a MI DPMS .308 SS12 free float handguard and low profile gas block. I removed original gas block with Picatinny rail but tried to drive out gas tube roll pin which was a pain. I finally had to drill out roll pin with drill press. I've tried pulling out gas tube and it will not budge. Is it locktite in place or what? I've applied liquid wrench around tube and thru gas hole and roll pin hole to let stand for a while. Do I need to order a new mid length gas tube? Any advise would be appreciated.

If you had to drill out the pin, I probably would order a new one

I've heated gas block with a small propane torch and could not get gas tube out by pulling on tube near gas block with gloves on. Since that didn't work I put gas block and tube in the freezer for 6 hours and tried pulling gas tube out by gloved hand with gas block in a vise, gas tube would not budge. Back in the freezer over night and try again tomorrow morning. Any other ideas?

 

I order a new gas tube which is suppose to be here by Tuesday, if all else fails.

This morning after being in freezer overnight, I took gas block and gas tube to work bench and hit back of gas block with several hard taps with plastic pallet to maybe loosen tube. I tried to pull tube out by hand, but no progress. I put gas tube in leather padded vise and clamped very lightly and had gas block sticking out one end of vise. I then took plastic pallet and lightly tapped gas block pulling gas tube from gass block opening. After seperating the gas tube from gas block, all looks good.

 

My wife has some plans for this Saturday morning and probably most of the day. Later this afternoon or Sunday, I'll finish installing new low profile gas block and new MI 12"' SS Gen2 free float handguard to M&P10.

Glad you got it out. I'm of the belief that some of these factory installs are forced in place.
