Quoted: I'm building out my first EPC-9 (Aero Precision) and forgot to research how to mount a barrel to the receiver (as well as the muzzle device,) before buying everything. My bad. The barrel vise tools that come up when searching, seem to be for larger length barrels.. I need one for a 4 inch. Can anyone point me to a good one? I'd appreciate it, thanks! You will likely have to clamp the receiver. Not the best for MD work but you won't be putting any more torque with the MD than the barrel nut. If you don't have a vice big enough for a clam shell type device there are other ways.  You can also make a barrel vice out of some hardwood. A rosin made from flour and baking soda helps to keep it from rotating.

A couple of bar clamps go a long way. Might not be the most convenient, but they get the job done.

Hold the receiver. Barrel nut torque nor MD install torque will be an issue.

Below is the best for 9mm uppers and barrels. Those 2x4 homemade jigs are so hokey. Spend the $$ and get the correct tool.

A simple strip of leather around the barrel gripped in a bench vise works great. Leather grips well. Clamp as close to the muzzle as possible. That ought to be easy on a 4" barrel. Angle the barrel up to access the muzzle device.
Everyone has an old worn out leather belt or strap of some sort around, so its free.

Quote HistoryQuoted: Pfft….. I can also put a motor together without a torque wrench and it will work but most likely have issues if ran hard sooner or later. Not even relevant! Use of home made fixtures instead of store bought fixtures is akin to whether you would rather put your motor together on a wood bench or a metal bench, not whether you torqued your fasteners. |

Same difference…… a workbench can be anything. A specific clamping device for a specific item, is just that. |

I don't even use a vise anymore. Just put the clamshell around the upper and clamp it to the table with a big C clamp. Works great.

Don’t get me wrong, there are instances where specific tool(s) are require for a given task. But there is absolutely nothing wrong or incorrect with using wood blocks and clamps as a means for securing a barrel or receiver (or to drive a piston out of an engine being rebuilt). In many ways they are superior. Every ‘jig’ has to a greater or lesser extent some amount of play. Wood will mold around the surface clamped vs touching a single point or surface as a jig does once torque is applied.
An $8500 dual plane spectra physics laser is a great tool made specifically to hold plane. But $20 spent on a plastic bucket and 15-20’ vinyl tubing taped to a stick is in every way equally as accurate finding level. Some of you guys remind me of the Harley riders that only ride if every piece of clothing on them says Harley Davidson. |

It really baffles me. Someone will spend a minimum of $700 on parts to build a rifle but won’t spend an additional $100 for the correct tools.
I can build a house with a hammer and a pc of string with a plumb but a cordless drill, air nailer and a real level sure do make it easier, faster and a better build in most cases. There is that guy that has $2500 worth of firearms but won’t spend $500 minimum for a safe. He just locks them in a closet or puts them under the bed. Don’t be that guy just because you can. This isn’t GD so carry on with y’all’s gunsmithing 101. |

If it gets the job done correctly without damaging components, who really gives two shits?

I am more than willing to buy tools, former diesel tech with all Snap On hand tools. When I was a kid I rebuild my Honda dirt bike engine without a torque wrench and changed the tires with screwdrivers. It worked fine. As a teen I did engine swaps with a tractor loader, not an engine crane. Worked fine. |

As a teen I did engine swaps with a tractor loader, not an engine crane. Worked fine. As a teen, I rebuilt my Mustang motor and transmission with basic garage tools many times. The motor would work and ran well but something would eventually break or not work as well as it should because of the high HP. Once I started having it built and tuned by a professional with professional tools, it always ran better. Now the dirt bikes, lawnmowers or compressor motors didn’t really matter because they were just toys/ items that did not really matter if they just stopped working. One build, maybe some duct tape, a screw driver and a used tire but multiple builds benefit from the proper tools. |
