Looks great just a bit long - my tube not threaded that deep.

Caps are very well-made excellent machine work. End caps were able to be screwed on all the way by hand. Excellent product I will be buying again .

Very good Machining and attention to detail. Would definitely buy again only I prefer the aluminum but bought stainless steel. A bit heavy but still does the job.

Another Precision part from Twin Tech Tactical. Five star 5 * 5 * do I need to say more! Everything that this company makes is 5 * you cannot go wrong doing business with these people.

Another solid quality piece. Fitment on the wix tube is on point!
Also like to note it you get the "filter cups" there is no rattle noise.

I ordered a single blank end cap in stainless. It was shipped promptly and the fit and workmanship was flawless! I don't see how it could have been better and I'm a part time machinist/gunsmith.
