Default Building my first AR

so ive been tinkering around with my fal, old marlin and recently installed some new sights on my glock. ive been on the edge about getting one, but with the stuff going on lately i didn't, and i really like working on my guns so i figured maybe ill just build one

so i have been googling my butt off, so i thought i would see if there was anyone on here that has built one before or anyone with general knowledge that might have some advise

so far all ive ordered is my stripped lower reciever from a local guy here, its a MAG Tactical alloy one

so from here i need the parts to fill it, and most of the kits i see seem to be the same for the basic parts, but some have a 2 stage trigger. i read a bit up on it, but not sure that's something i need any ideas on this?

i plan on building a carbine length flat top, with a holo sight and back up iron sights, just want to make sure i put good parts in it, maybe not the very absolute best but i want a nice rifle when im done

thanks in advance

also AK tactical has a full lower reciever parts kit minus buffer housing, buffer and spring for 80 bucks. its DPMS and i gotta say for the price its worth it. THe trigger is crisp and not a lot of dead space. You might want to look into it.

It is easy. Way easier than you think. BUT, you need to pay attention and go slow. The only thing that I find the least bit technical is putting the barrel on the upper.

The rest is super simple. There are some tricks that make things easier but it is a good project. JUST DO IT! ahhahaha

i haven't researched any into the barrel, but it looked threaded, so im guessing it will have to end up being clocked properly to align the gas system? but i will probably have the local guy install the barrel

not exactly sure yet, right now just trying to see about finding places with pieces and parts, but im just buying a little at a time it will be a long term build so long as i can stay focused, found a FAL parts kit at the local shop today wouldnt mind having another Fal so hopefully i can resist

the barrel has a pin in it that aligns the barrel to the upper. the barrel nut needs to be torqued down and aligned for the gas tube.

oh i plan on building it myself but if theres something i feel i cant/shouldn't do i wont. barrel assembly sounds easy but there has to be something to measure and set the headspacing, so thats the only thing ive seen so far that i would probably take to the gunsmith for, mainly because id assume theres some special tools involved, i will post pics as i get parts and work on it, right now my lower is 4-6 weeks out as of a week ago

AR's head space themselves, as long as you get your bolt to fully engage into battery its spaced. Just ensure you have the propper length gas tube and that its exactly parallel with the barrel or you will have binding issues with the bolt/tube junction.

I have. DSA upper a fee S&W upper and 1 LMT upper. All 3 are great DPMS is good too. You should decide first if you want a front site tower or low profile gas block and select a rail system

i do not want a front site tower, i want the low profile, and im still researching but i think im going to do a free float fore end with a rail system, and i would like to have the top rail be a continous(sp?) the gap where the barrel nut bothers me lol. ive been looking at an upper made by Aero, only seen a few reviews but people seem to like them, heres a link

http://aeroprecisionusa.com/shop/cop...r-receiver-kit

kind of a neat idea i think

Default Re: Building my first AR

So another question is I'm pretty sure my buffer and buffer spring are carbine, so when choosing a barrel does that mean I need to get one with the carbine gas length? I did a little reading and what I found is the shorter gas system is fairly harsh compared to the mid length and rifle, I was looking at some barrels with mid length, if I have a carbine buffer and mid length gas system will the rifle have trouble cycling?

It's a different weight buffer and spring is all. I run carbine length gas tubes and buffers you can swap them out when you swap uppers .

The VA Milspec buffer kit comes with a carbine buffer and spring. Your buffer length is dictated by the length of your stock tube (in this case carbine). The carbine buffer is the correct one for a midlength gas system and carbine length stock.

My opinion is go with either a full length gas tube or carbine
The 10.5-14.5-16" all use carbine and same gas set up as buffer. I believe the 20 uses long length tube . I tend to avoid " mid length" or barrells that aren't standardized . I figure if the military uses it as beats it to death its good to go for me as I am not some self proclaimed SEAL/Ranger/Starship Tropper hi speed guy

It does seem that different uppers do require tuning on the buffer. I found that I needed an H on my 14.5 carbine gas tube originally. I had to step up to a 2h with my suppressor on. The rifle would cycle fine unsupressed with a 2H so it stayed. No bolt bounce with it.

I have a midlength 14.5 now. I have been able to back off on the heavier buffer to standard weight for normal, and I forget H or 2H with my can.
