Tube diameter is thicker than you think, and could be problematic

Long story short (due to character limitations), the larger tube diameter and U-shaped notch beyond the threaded portion ended up creating a huge headache for me during my install, resulting in the destruction of the tube, the castle nut, and the Spike Tac QD endplate I was planning on using. I was not very happy.

<br>FYI, for those of you using a Magpul castle nut wrench... it will NOT fit around this tube, so plan on using a different wrench for your install.

Good price if it's what you want.

This buffer tube will NOT work with the Tailhook Mod 1 arm brace. The specs for the brace are 1.17-1.20. The diameter of this tube is 1.24. Disappointed but there was no info regarding sizing in description.

Can't go wrong i feel.

As my name says I'm a Noob at AR building. But not a Noob with Fire arms in general.
<br> The treads do not feel gritty when installing. Tube feels hefty. Castle nut and End plate feel suitable. 5 stars.
<br>This was an unbeatable price. An equivalent buffer kit from another site.
<br>Rhymes with Crown-snails, wanted twice the price. And about a week to ship. This was shipped supper fast. Like Amazon Prime fast. With just basic usps priority. It was at my door in three days, from 1,579 miles away.
<br>While i am new to building ARs. I belive all my purchases going forward, might just end up coming from this site.

NICE

Attached to the back end of a Radical 10.5" pistol upper. Ran about 600 rounds of steel and brass in one session and have nothing but good things to say. No failures of any sort.
