 Just started on my First AR build. I'm pretty hany with tools so I don't think I'll have major problems. I do have a couple questions about differrent brands. Has anyone heard about White Oak Precision? Is checking the head space required for most builds? I purchase 2 Lowers at a recent gun show.....DPMS with consecutive sn's. I'd like to build one as a 16" CAR and 1 as a longer standard rifle. Also, during my research iI have found Uppers with picatinny rails welded to them that would change how the barrel is attached. Is there any real benefit to this configuration?

| I can answer one question right off. It is NOT necessary to check headspace on a new build if you use a NEW barrel and a NEW bolt (both from reputable sources, of course). The design of the AR is such that any precision work was done in attaching the standard barrel extension to the barrel, based on the dimensions of a standard bolt. My first build was made up of parts I bought as I could afford them. I have no idea who made the bolt, but the barrel was GI surplus. That rifle was close to a tack driver, and when I did have the headspace checked, it was perfect. Don't sweat it on this issue. |

Thanks....I'm building mine the same way...as i have funds. I could probably buy it built cheaper, but..............!!!!
I can buils a little at a time and not go bankrupt! With the new Pres in office I thought this is the time to buy the lowers. I dont have any experience with gusmithing but I got 40 years of gun knowledge. Should I purchase the same brand upper? OR....are most uppers going to be the same? |
 I meant to also say that in 1982, I purchased 2 Colt ar's new for about $500 a piece...........wish I still had them. Neither one had the Forward assist on them. Even though I didn;t lose money when I sold them in 1987...What would they be wort now!!!!Hind Sight!!!

Quoted: Has anyone heard about White Oak Precision?
Yes. Good stuff. See http://www.whiteoakprecision.com/ and http://www.whiteoakarmament.com/ Quoted: Is checking the head space required for most builds?
Maybe not, but I appreciate the peace of mind. YMMV. Quoted:I have found Uppers with picatinny rails welded to them that would change how the barrel is attached. Is there any real benefit to this configuration?
LMT's monolithic upper and VLTOR's VIS are like that. IMO the benefit is more theoretical than practical. Theoretically, there is less stress on the barrel nut in a monolithic upper. Such stress could theoretically change the point of impact on a rail attached to the barrel nut, but I haven't seen much complaining about non-monolithic rails here. ETA, they also tend to be heavier than, for example, Daniel Defense's rail systems. |
I'm going to check out White Oak Precision...they look prety good on paper!
I saw somewhere that a piece of cord was tied to the bott of a magazine to give it a loophold....they used #550 cord or something llike that. Where do you find this type of cord? Is it like parachute cord?

Its paracord and you can find it at a lot of army surplus stores as well as all over the internet. If your looking for a pull tab like that, you should also check out magpul. They have ranger plates that do the same thing but are made of semi flexible plastic/polymer (according tot heir website it's: pliable Santoprene overmolded onto a stainless steel plate). They basically replace your mag's floorplate and you don't have to tape paracord to the bottom of the mag.
I think you can find the ranger plates for cheaper elsewhere, just used magpul's site for the reference picture... |
