Idea's on how to torque and time AR-15 barrel nut without vise

Recommended Posts

Looking on getting any idea's on how to Torque down and time barrel nut for my AR15 without a vise, it probably not going to be possible but hoping. I can easily go out a get a cheap vise fro harbor freight but I don't have the space or table to install one. If anyone knows of a shop/place in NJ I could go and rent a vise for 5mins that would be awesome.

How about laying 2 short 2x6s on top each other like a step, lay a towel over them, lay your upper assembly with the hand tight barrel nut on top, and cover it with the towel. Now drive your car up on the lower. Tighten away.

By the time you buy a vise, upper vise block, torque wrench, barrel nut wrench, anti galling compound and find a place to bolt down the vise, you could have been to and back from a gunsmith or armorer three times.  If you try to rig something up, it's going to take even longer and there's a chance you will be making another trip to the LGS to buy a new upper receiver.

Go support your local smith and save yourself a lot of hassle doing it.

The barrel extension determines headspace. Can't change it.

Well, duuuh.  But it's still a good idea to have a newly barreled upper head spaced.  It's not checked for adjustments, it's checked to verify the rifle is safe and will function reliably.

Maybe it can't...Maybe it can. I have a well known barrel manufacturers barrel that didn't pass my HS check.  Now I am new to all this but checking HS is pretty straight forward with a HS gauge. I checked mine a half dozen times thinking it must be me before getting in touch with the company. They had me send it back to check it. They sent it back to me and said it passed their inspection. Well I of course checked it again and it passed! So maybe it can't be changed but maybe it can be "adjusted" I don't know what they did but the barrel didn't pass my checks before I sent it to them. Anyway...can't hurt to have it checked.

No they can't adjust headspace on an installed extension. 

I would also argue that the bolt is more likely to be at fault than the barrel extension, at least from any reputable company.  This is because the race to the bottom on the sale of cheap bolts is WAY ahead of the race to the bottom on the sale of cheap barrels. 

I would further argue that more likely than either of those is that an inexperienced user is going to do it wrong and get funky results. The internet is full of stupid suggestions on how to complete it. 

Like right now I'm looking at one that says you should do it with a min and max gauge,  except it treats them like a go and no-go gauge. Which isn't correct, as the brand he is using, the go = a .223 GO gauge, and the max = a 5.56 Field gauge. YEs it shouldn't close on either a no-go or field, but starting on afield from new you may actually be able to close on a no-go.  I'm also looking at another one that talks about owning one gauge and a piece of masking tape. And another that is making due with masking tape.  bolt needs to be disassembled and cleaned prior to check. Barrel extension lugs need to be cleaned out too in case anything is hiding there. 

The dudes at an iso 9000 certified factory with CNC equipmetn, experience, and a QC chain that has the right headspace checking tools will do a better job than you more than likely. If you are checking, you should probably also just call/email the barrel maker and ask what bolt they headspace to. Then don't cheap out on the bolt.

HaHa funny. firstly not a millennial. While I do have tons of tools I don't posses a vise as I live in a co-op apartment at this time and have nowhere to place one.  Since I had to get the muzzle device pinned  and welded due to NJ being a semi anti gun state I just had Mike at Tier 1 kill two birds with one stone. Thanks shooter28 for the heads up on Tier 1 defense.

Yeah checked that already, max opening for table top vice claps I’ve found is 1-1/2 to 1-3/4” my upper vise block is 2-1/2” thick. 

Vice to board. Board clamped to table.

if all you see is roadblocks you’ll never get anywhere!
