This is a Remington model 34 inside magazine tube. It is a reproduction made exactly like the original. These are extremely hard to come by and we finally have some available!
The brass portion measures 18 1/4" and the OAL is 20 1/16".
Very nice part. The end cap is a bit smaller than an original and the knurling is finer. Works wonderful compared to the slightly bent original with an old spring. Original end cap is about 0.475 wide this one about 0.445. Swapping end caps cures this. With original tubes costing two to three times more and hoping they are straight with a good spring, this is a wonderful cost effective replacement. Once installed I don't think most people would know it's a replacement. If you want a quality replacement that works look no further.
