Mil-Spec 7075-T6 Carbine Receiver Extension / Buffer Tube - Raw - 6708 Review

Great project buffer tube!

Bought three and after some cleaning and deburring, sprayed them with Aluma-Hyde, they came out great. Will be buying more when they come back in stock.

Quality tube fits ar15 stock and lower well.

Quality tube fits Ar15 stock and lower well. This fits most Ar15 mil spec stock due to its thin Aluminum wall that not all mil spec tubes are the same. Some fits some stock but not for other mil spec stock. This fits my most stock.

Awesome.

Item was great, as described. In the raw, so it should be fun to paint.

In-spec, perfect for my build

I was looking for an unpainted buffer tube so I could polish it up and mate it to my PMACA 10/22 chassis. Fit was perfect; polished up nicely. Attached a minimalist stock at the end of it, and now I’ve got the perfect lightweight 10/22 build.

Perfect Buffer Tube

This tube is a perfect neutral tube for any build . I bought one as a place holder for my newest build and liked it so much i left it installed. I didn't experience any problems with it and have tried several butt stocks with it and it worked great with all of them. Buy a few and have them on hand for your next rifle.

Raw tube

Inexpensive. only complaint is that tube has some dark discoloration on milled surfaces. looks like something acidic darkened those surfaces. Its in the medal not applied on top

Exactly what I wanted

Was l little rougher than expected with the finish, needed to be sanded to clean it up but fit as it should. Worked great to anodize to custom color.

Raw buffer tube

the buffer tube is mil spec - the quality is good, it's really raw so you do need to sandblast it to get your finial finish - this is great for cerakote or Diyer paint job...

Tubes were raw but worked as needed. Can paint them any color to match my build.

Raw buffer tubes??

I ordered two of these because they we cheap. After receiving them and cleaning them with some sand paper they turned out Great!! I started a custom raw build and these are toe go to buffer tubes just for that. I used 320 grit to start and it cleaned up most of the harsh oxidizing on the aluminum then I went with 800 grit, 1500 grit and finally 2000 grit to give it that shiny finish.… read more They fit snug and perform great. The smooth finish lets the stock slide gently across it with ease. I have not fired my rifle yet but I'm hoping as snug as everything was on the inside and out with it being 7075 I'm hoping it baffles the twanging sound of the spring. The spring and buffer fit perfectly inside of the tube with minimum to no play at all. Pros: Quality made Looks great finished in a raw form Tight specs and great fitment Cons: Some work needed for finishing Over All; I would recommend this to anyone looking to do their own custom builds.

Perfect Buffer Tube for builders

I have been painting custom AR's and this buffer tube is excellent and is of excellent value. It is 7075 grade and I don't have to blast any finish off of them, ready for paint. If you are building/painting ARs, this is an excellent buffer tube that is Mil-Spec for an awesome price, especially how everything seems to cost more right now.
