Assembling an AR-15: Proper Building Methods?
« on: February 25, 2013, 02:23:19 pm »
Rock River likes red loctite a lot. Seems they prefer it to the proper building methods...you'll also find it on the reciever extension.

Okay, I'll bite. What are "proper building methods"?

    Staking the critical places (and properly) such as gas key, castlenut/end plate, properly torquing barrel nut and handguard hardware (with such a wide variety of mounting methods there is no generic guide)...lets also not leave out points such as out of spec chambers, cheap bolts, and dremeled feed ramps.

    The shoddy makers tend towards loctite (or no securing at all) in an effort to save time and labor. Bubba building a gun does it because hes lazy.

    You may ask whats wrong with loctiting the castle nut? Well mainly its a pain if you want to change the reciever extension plus its just a shoddy way of doing it. The gas key and barrel nut however are a different story...

    Use a torque wrench when installing the barrel assembly to the upper receiver as well.

    Stake the receiver extension, like already mentioned.  I will admit that my RE isn't staked (thats because I don't have the tools to do it).  I'll get that fixed as soon as I can.

    The gas key is a must.  You don't want that coming loose at all.  Look into the MOACKS tool.

    FMJ you can stake with a punch.

    I know, but I don't have one nor do I have a vise to hold it steady. 

    I actually built my lower in an unorthodox manner (eg pliers instead of roll-pin punches, etc).

    You don't HAVE to stake the receiver extension. Torque it to spec and it should hold. Check it frequently and you'll be fine. That said, if you have no desire to change your extension, there's no reason not to stake it.

    That's not unorthodox. That's how most people do it. Even for me, I don't buy a lot of those specialized tools.

    I was also sitting on the sofa doing it on my lap while having an ice cream sandwich.

    If you are eating an icecream sammy... you might not be doing it right.

    You should hold the sammy with both hands.

    I think I had like three the day I built my lower, but it's OK I burned it off at Krav Maga later that day.
