| How are you guys holding your lowers while installing and removing receiver extensions? I have a magwell block that I have been using, but it does not give the support that I would like to have. The TM manual states to use blocks of wood, but I am afraid of marring up the lower. Once you start getting up to toward 35ft. lbs., it seems like it could put a lot of stress on the lower receiver. |

35 lbs of torque is actually very little... I can apply 35 lbs to a lower while holding it in my hands. Wow... your pretty strong  . 35 ft. lbs. is the minimum requirement for barreling a receiver too. Can you barrel a receiver with your hands? I guess I better start working out! Anyway, I have a torque wrench and tightened it to 35 ft. lbs, but I became concerned as I did not feel the magwell block was giving me enough support. Does anyone know if there are any tools (other than your hands) used to hold a lower while doing this?
ETA: Not trying to be a smartass, just looking for a proper tool. |

There's a lot more to grab onto with a lower receiver, but yes, I can. The secret is to rest the torque wrench on your thigh, and use both hands to twist the upper.
Trust me, 35 ft lbs is NOT much. Back in the day, when I was still working as a mechanic, we used to play with click-style torque wrenches, just by grabbing the head, and clicking it, gradually increasing the torque on the handle, to get to the point to where you couldn't "click" it, and then hand it to the next guy to see if he could... Stupid, I know, but it was a way to pass the time, on slow days... Trust me, 35 ft lbs is not much. |

I was installing a UBR, so I did not get to use a castle nut. It installs more like a rifle tube. The magwell holder did the job, but I am always paranoid about putting stress on the lower receiver. I would literally poop my pants if I bent a lower (not sure how easy that would be to do). I was just thinking that if there was a better tool to use, I would like to know about it. Thanks for the reply! |
