POTD: SM15

@Vitor Roma If you've got a semi auto AR15 I don't think it offers you any benefit since the gas tube only tends to become prone to bursting under prolonged full auto fire. I've never heard of suppressors causing them to burst frequently either though I'm sure its happened to someone somewhere.

An adjustable gas block would probably be of more use to someone running a suppressor on a AR15 anyways since the suppressor would over gas the action unless you turn it down some.

Their marketing is a bit sketchy over all to me since I wouldn't consider the gas tube to be a 'weak link' (their wording). I'm sure a inconel gas tube is more heat resistant and all but they're selling a solution to a problem that doesn't really exist for AR15 owners.

Now if you were in the military with full auto M16's/M4's and expected to be undergoing situations where you were frequently mag dumping in full auto (virtually never happens and even then the stainless gas tubes tend not to burst) then yes there would be some sense in buying it.

IMO if you wanted to improve reliability or durability of your AR15 your money is better spent on a better bolt and/or extractors 1st then maybe 2nd work on tuning the recoil buffer and spring assembly. Gas tube would be at or near the bottom of the list for me.

@tts Adjustable gas block is for competition. Period. Has no place anywhere else. Which is fine, cause there's a lot of competition-only ARs. It's good for tuning the gas down so it runs with *just enough* gas for your lightweight bolt carrier and reduced power springs and barely-there buffer weight, and along with a huge muzzle brake gets your recoil down to pretty much nothing. Split times, bro.

@Sianmink It has a place in a lot of other places. Suppressors and different climates make an adjustable gas block a big +

@Sianmink Other guns have adjustable gas blocks by default. There is nothing wrong with having one particularly if you run a suppressor on your gun.

@Vitor Roma I'm curious also. They have a video of them running full auto and melting a stock gas tube, but don't show a comparative video using their "superior" tube. Hmmmmm......
