A torque wrench is overkill, IMO. I'd stake it though.

It needs to be tightened more than you can hand tighten with one of those short stock wrenchs. Since the average guy can break off a 3/8" bolt with a 9" wrench at about 40 pounds, not so much. Snug it down firmly and stake it. |

Because I'm really bad about OVERtightening stuff, I use a torque wrench and Spike's castle nut wrench, but a lot of people get by with just "good and tight" It does take more than one of those 6" or 8" tools to get it tight enough. The castle nut isn't going to just wander off if you get it "good and tight," but staking makes sure of that. No Loctite. I use an automatic center punch to stake with - quick, easy, no hammer to bounce off and hit gun/face/hand, etc.

I used the "good and tight" method. (disclaimer: I'm a mechanic so that is what I do for a living) I torque the barrel nut but not the castle nut for the buffer tube. I did not stake mine in case I wanted to remove it some day. If it were a personal defense firearm I most likely would have staked it though. I also figured that if it ever came loose I would decide at that time if I would stake it.

38-42 FOOT POUNDS.
Also, use grease on the threads for the castle nut. |

No loctite. Use grease if you don't plan to stake it.

Thanks guys, all taken care of, thanks to all the replies. Its good and tight, did not bother to torque down, no loctite, and properly staked. Its my first build, and I plan on it being an addition to my home defense arsenal. I appreciate the input!
Thanks a bunch-TS |

I'm certain that an average person can easily get 40 ft lbs with a castle nut tool. Quote HistoryQuoted:

That's the problem: "feel" is absolutely nonrepeatable and prone to error in all sorts of ways. Since I tend to overdo, I'm even more careful when I use a torque wrench...but I get it right that way. |
