Only tubes I buy

For something that you never see it's flawless. Fit into blocks is always snug enough to hold position while installing the roll pin. The black melonite finish just adds a little extra to your to your custom build.

Nice gas tube

Works like it should.

Works 100% as expected

I was amazed at cost for a small tube of steel, and budget guided my purchase. I installed this with a low-pro gas block on 14.5 inch barrel. Tube was straight with a slight rise by the barrel nut - no clogs, no dents etc. Works as expected for >1000 rounds so far. Can't live without it if you want your BCG to cycle...

Worked like a gas tube should

Holes for pin and gas block lined up. Not sure what else to say about it. I might have paid more than I should for a tube but whatever it works.

Great Value!

Excellent quality with the black nitride finish to get rid of a potential reflective surface, and includes the roll pin unlike many gas tubes out there. Excellent value and worked great with my gas block.

a good value

fits & looks great. good quality. no problems with installation.

Best Gas Tube on the market

These gas tubes are hands down the best out there, and they blend in with the barrel so if you are running handguards that you can see through you won't have a big silver gas tube staring back at you.

Good product

Came with pin and was a very easy install. Other gas tubs are 7 inches. The Spikes is 7.5 inches and worked great. Nice finish to metal surface.

functionality fine

As far,as functionality goes, this product is fine. My only problem is the poor job on the melonite finish. A few spots where rubbed off. Looks too me like a problem with the coating process. The part was probably handled handled improperly before it was coated. Otherwise it's a fine product.
