Gas tube check
Hey everyone. I have a carbine length Smith and Wesson M&P 15, which has an aftermarket YHM gas block. WHen I installed the gas block, I used my existing gas tube.
I would like to have a couple extra tubes in case of failure (I know, unlikely). Is this the proper item as long as I select carbine?: http://www.midwayusa.com/product/997...la=ProductDesc Thanks all!

Measure your gas tube length to be sure.

If you selected "carbine", it is the correct length. If you're going to get it, get the roll pin too.
But there are plenty of other items to stock as spare parts before a gas tube. Firing pin retainer Complete bolt Cam pin Extractor Extractor spring Extractor o-ring Gas rings Detents (for take down pin, pivot pin, safety selector) Springs (all flavors) |

When I get some spare time (nyuk!), I'll post some sources for some of the springs and the roll pins from bulk suppliers like McMaster and Fastenal. There's not much special about the compression springs for the detents and the roll pins - gunnies can buy them in huge bulk.
Some people try to shove things like pipe cleaners and such down a gas tube to clean it. I personally think this is a mistake. If someone really wants to clean a gas tube, pull it out of the rifle and soak it in something like MPro-7 to soften up the carbon, then spray brake cleaner through the tube. |
