Had the afternoon off so I spent some time putting together my AR-15. Guess I timed buying the parts (October) right...sheesh...
The gear:
I mostly used these guides:
Really, it's not hard to build your own AR-15. A little harder than I thought, though. Major tripping points:
Still have to put on front/back sights, and install the optics. I also don't have a castle nut tool so I ordered one to tighten up the stock.
Two things disappoint me:
Now I want to build another one
The gear:
- lower I got from JC Weaponry - great guy
- MOE upper (1:7 16" chrome)
- MOE M4-style stock
- CMMG 2-stage LPK
- MOE sights
- Awaiting arrival of Burris rings and a Bushnell Elite 3200 scope
I mostly used these guides:
- ITS Tactical YouTube: DIY AR-15 Build - YouTube Really liked this series, though some of the instructions were specific to the parts they chose. Still, very helpful to see the work as it was done.
- CMMG LPK video: CMMG Lower Parts Kit HD - YouTube Man someone spent a lot of time doing the video rendering for this. Beautiful vid.
- BuildYourOwnAR15.com - not that great a guide, really but for $10 it wasn't bad.
Really, it's not hard to build your own AR-15. A little harder than I thought, though. Major tripping points:
- Hammering the roll pins in. This wasn't hard just kind of a pain.
- I didn't have any problems with the spring-loaded detents but only because I read numerous times that they are easy to launch/lose.
- Screwing in the stock with the takedown detent, buffer spring, etc. was ridiculous...took a while to get that all done.
- The CMMG 2-part trigger is different than every other guide. Took me a while to realize that the disconnector and spring in the box weren't needed and that the trigger was already assembled. CMMG customer service was very helpful.
Still have to put on front/back sights, and install the optics. I also don't have a castle nut tool so I ordered one to tighten up the stock.
Two things disappoint me:
- The hammer and trigger pins fall out at the drop of a hat. Seriously! I ordered some of the KNS no-walk but these are ridiculous. Don't know if something is mismade or misinstalled.
- The two-stage CMMG trigger is...well, let's just say I have a different idea of two-stage. There are two stages, but it's a light first stage and a very heavy second stage, which really defeats the purpose. I am going to reexamine all of that setup in case perhaps something is not correct but it's not adjustable and it does dry-fire correctly so I don't think I put it together wrong.
Now I want to build another one
