Full Length M4 Tube

Recommended Posts

Full length US made M4 magazine tube in a parkerized finish. Tube is stamped US very small near the base of the threads. Matches the receiver really well. Comes with Wolff performance mag spring.

$100

I honestly have no clue. I am positive it's not carrier comp. Fit and finish is great, the only markings on the tube are "US" very small at the receiver end.

Could be anything, but $100 is a good deal as long as it's not cardboard, lol
Oh that is classic Unobtanium, There are a few manufacturers out there, most important is check the lengh and make sure the threads are a true straight cut and not modified acme (or at least a very good modified acme.)

I was just about to pipe in ... All my FL tubes are marked with "U S" and a batch number stamped on the collar at the receiver end. Also I never did straight parkerizing, all the tubes have been "gun kote" "diamond- kote" polymer finish most matte black color. And yes, a square cut thread.

I still have tubes, and receintly reduced the price to $145 including shipping.

I have one of yours and the threads are as good if not better then the OEM. Some manufactures skimp because the square thread is harder to tap (or so I have heard.)

Thank you "d" , appreciate the good words. I do my best to make a quality product.... may have been the first to make the M4 FL tubes, been at it about 5 years now. And yes doing a true square form thread took a bit of development work.
