Barrel torque magpul wrench

[MegademiC]

Being that the hole for the torque wrench is 2.25" from the barrel nut wrench portion, I assume the torque wrench should be inline with the magpul wrench, not 90 degrees, correct?

90 degrees is correct. If you have the torque wrench inline with the magpul wrench, then the torque values will be higher than you expect.

What Will said. It wouldn't matter if hole and socket of the wrench were 1 or 3 inches apart it's always 90 degrees. You can calculate the corrected value to use it inline but it isn't worth the effort.

Per 9-1005-319-23&P the torque wrench is inline with the wrench. I wouldn't overthink this.

Shit. Now you guys got me lost. I have what I cosnider to be 3 knowledgeable posters disagreeing. I ended up using it inline and final torque was around 50ft lb so I guess it wouldn't matter.

IG, can you confirm inline and that that wasn't a typo? I know the castle nut goes 90, but inline barrel wrench?

You can find people online doing the math and YouTube videos demonstrating why 90 degrees is correct, regardless what some government manual says.

ETA: I wonder if the "manual" takes into account the wide variety of wrenches on the market today, or if it's specific to certain tools.

Yea, screw them military manuals. I mean, what the **** do they know about anything anyway, amirite?

Follow the damn manual and everything will be just fine. It's not they wrote the damn book on the subject or anything.

Read his last sentence. The spec, regardless of the wrench placement, is a very wide range. It's like a 50lb window and you basically have two choices dictated by your gas tube. Loose or tight. Pretty sure you will be much happier with the results of the 'tight' option.

If you want the most accurate torque value that is detailed by the instructions for the handguard you're installing, then the torque wrench should be 90 degrees off the barrel nut wrench.

Unless I'm mistaken, 9-1005-319-23&P refers to a GI barrel nut wrench and a normal milspec barrel nut, for which the torque value is basically irrelevant once past 30-35 ft lbs anyways, since it has to be timed to the gas tube hole. But the inline orientation presumably takes into account the difference.

Using the two wrenches in an inline orientation will result in a higher actual torque on the nut than what you set the torque wrench to. However, it's not that much if the torque socket is just a couple inches from the center of the barrel nut wrench. If you want 40 ft lbs and end up with 45, it's not detrimental to anything.

The Colt drawing says 30 ft-lbs, not to exceed 80 ft-lbs. No mention of tools or anything else. This would indicate that the nut is to be torqued to 30 to 80 ft-lbs, however you choose to get there.

And, while the manual shows the wrench in-line it also states "Torque is measured when both wrenches are used together," indicating that the length of the wrench must be accounted for when torquing the nut.
