Looks Good

by -

Havent installed it yet but feels solid and well made. Was actually a bit heavier than i expected but that doesnt mean much as im still inexperienced.

Quality Product

by -

Part came in a large ziplock, display size bag with product information and a black oxide coated roll pin. The tube has an extremely smooth finish its entire length that could be described as polished stainless. No machining burrs around the gas port, roll pin hole or the bolt carrier extension. Length was as described. Fit perfectly into my J-P adjustable gas block like a glove. I’m a machinist and I’m impressed with this product and will replace my other rifles with this part. A+

I can't recommend... faulty porduct.

by -

Can't recommend this product. I recently had a chance to test fire a new build that I installed this tube in, and the bolt completely failed to cycle. Took it back home, took the tube out of the block, placed my finger over the port and blew into the other end with my mouth. Air easily escapes through the roll pin holes of the tube and some even out of the front.

Maybe just one faulty unit out of a bunch, but I can't give this product my indorsement.

Did not include roll pin

by -

Supposed to include roll pin, but there was nothing in the packaging except the tube.

Solid Tube

by -

This product is a solid and highly polished. No burrs and no complaints so order this product!

Bought a mid-length, got a carbine.

by -

Ordered a mid-length, manufactures packaging said it was mid-length... So either i am the proud owner of the worlds only 14.5 rifle length barrel, or it's a carbine tube :(

On the positive side... the gas tube looks to be decent quality, it came with the roll pin like it was supposed to. I'll end up using it in a carbine build.

Nice gas tube.

great tube for the price. 100% satisfied with it & would buy again for all my builds

Stainless with good quality roll pin……


This is a great gas tube for a great price, when you find quality parts you always return for more, so far I’ve bought 2 for two builds, I coulda paid more for a name but why, these work great almost too easy to install 😊.
