Hi Guys
Is there any other other way to lock the upper of an BAR 10 in a vice to install a free float rail without useing special vice blocks??? I don't want to have to buy vice blocks for a one time use. Thanks Tim MoblMec |

Some advocate using blocks of wood, or pieces of that white cutting board material.
I'm waiting on the blocks to be in stock. I got one of the PRI upper pin vise things, but I don't trust it to do barrel installations. (too much torque on the lugs) We need to start an equipment exchange list for these. One guy buys it, uses it, sells it to the next guy on the list for same. Just keep it going. |
| In a pinch, use a couple of thin wood blocks and turn a flat-top upper sideways in the vise. That is, the vise jaws are gripping the flat top & bottom surfaces. Not the best method but I've seen worse––-one guy pinning the rifle against the kitchen table while another worked the wrench, and it iturned out OK! |
| I have done it with the wood blocks, but be very careful. Make sure the block on the underside fits up to the pin stanchions and make sure to tighten enough to secure from twisting, but not soo tight it crushes at the ejection port. The risk of destruction is there. It all boils down to your level of acceptable risk. |

Or use the Panther Claw upper block. It's about the same cost as what badazzar linked to. Either way, USE THE RIGHT TOOL. We're not talking about buying a CNC milling machine here, but rather about $40 worth of tool. It's an inexpensive way to do the job right. |

It's well worth the $40 to be safe and not ruin your upper. I have access to a milling machine and it's still worth $40 to just buy the fixture, instead of spending 4 hrs, plus material cost to make it. If your worried about the 1 time use turn it over on the EE drop the price $5 and it will go quick.
