Am I missing anything to complete the lower (or its twin)?

I have all the videos bookmarked.

The ultimate goal of the rifle isn't clear, so let's say general purpose target usage.

Thanks!

yeah, looks like you got everything to finish the lower.

Should be no problem except the work.

A good set of instructions or guidelines. Some thing shave to be done before others.

Let us know what videos you personally found the most useful.

Some say a clovis pin (1/4"X2") is useful in assembling the lower.

I find that's the best way to assemble the pivot pin. Easy as 1-2-3.

I meant to say clevis pin, not clovis pin.

I knew what you meant. Regardless of how you spell it, it's a great way to assemble that pivot pin.

i just built my first lower and I recommend watching the brownells ar 15 build videos. they show it step by step and you can stop and start and backup as needed. they are very useful.

 

[j_h_smith]

There are many great videos and diagrams on the interweb. Find one that you like and follow it through. Just don't force anything. Painter's Tape is also a good tool to use, so you don't scratch up the receiver.

Good Luck!

do you use it like the brownell tool? damn that's a good idea.

This is really a good idea especially if you aren't using proper tools. I've scratched a couple of lowers installing a pin that wouldn't have happened if I used tape.

I recommend a diagram with all the LPK parts on it. I laid them out on the printout before I started. Kept me from searching for parts.

I used this CMMG LPK install video on my first lower, really helped me.

Not really that hard. Best tip I got was to be careful with the trigger guard and to place it in a large box as you work.....it will catch the loose spring that eventually jumps away.

Painter's tape, 1 gallon freezer bag to work in, and a razor blade to press down the pivot pin spring/detent as you thread the castle nut.

Also an automatic center punch to stake the castle nut. This can be done with a regular center punch, but this reduces the chance for messing something up.

 

[l730dc]

I use a credit card/ID for the pivot pin (Its super easy) ... and taped pliers for the roll pins.. they both work great.. I have no tricks for the castle nut.. I always use a castle nut wrench


.. you know what you're gonna do with the upper yet?
