AR build questions......
« on: June 21, 2012, 11:02:39 PM »
Do I need any special tools (torque wrench?) to put this together?

I saw a video of a kid who looked about 15 putting one toegether with nothing but a pair of vice-grips, a flat screwdriver, and a punch ....... I seem to recall that some stuff needs to be torqued to specs.....

What are the specs, and who is having a build party for the noob this weekend?

Also, I need a lead on where I can find poodles in quantity, as I'll have a gun just for them!

..... also, I need an a-3 carry handle/rear sight ..... anybody got one they don't need terribly badly?  I'd make an offer but am not sure what they cost new..... see? Noob.

i built two AR's.  the special tools, BK had and helped me finish them up.  you'll need to torque the barrel and barrel nut assembly and the stock nut.  i think they came out ok.  i think the torque is around 35lbs, but don't quote me on that.

Do you have a complete upper, or do you need to assemble barrel, handguards, etc?  I have not done that, but I do believe you would likely need a wrench (possibly an AR-15 multi-tool) to tighten the barrel nut and attach handguards.

Or are you just assembling the LPK in a stripped lower, and installing the buttstock?  If you are installing a buttstock, you will need a specialty wrench.  I believe the AR-15 multi-tool would work for that too.  I just went to a fellow gun nut friend's house and borrowed it for a few minutes.

If you're just building the lower, you don't need anything special.  If you're also assembling the upper, you'll potentially need some specialized tools.

I have a carry handle/sight for a flat top that's just sitting in a bin.

I admit it has been a while since I put together my lower, and I have only done one, but I swear I had to use a specialty wrench for the nut that secures the buttstock.  Did I imagine this?

It can be done without the specialty wrench but the wrench is nice to have.  Usually, they're pretty cheap too.  I'm sure several of us have them and wouldn't mind loaning to another member.

How much to convince it that it would be more useful atop my PSA (assuming the Brown Truck of Happiness shows up and the driver rings the doorbell this time..... darned brown-clad ninjas!)?

The upper is already barreled, but the castle nut on the lower looks like it needs a special spanner of some sort.....

How about $20 for the carry handle?

You can tighten the castle nut on the lower with a pair of slip joint pliers.  I've used a rag to keep the jaws from chewing up the nut or you can use the special "spanner".

Are you in Omaha?

$20 and a 6 pack, did you say? Sold!

I'm south of Omaha a bit, but the A3 carry handle/rear sights at Brownell's are like 75 bucks, IIRC..... I can make that drive...... maybe Saturday I'll find some time......  where are you at?

I also need a bit of blue locktite.... other than torquing/locktiting that castle nut, and adding a rear sight ...... I just need some P-Mags, a sling, dies, bullets, work up a load...... oh, and now I'll have to stock small rifle primers, too ......
