ar10

Well guys, I finally got out to shoot my PSA AR-10 (in .308). I've had the gun for a year and a half, and just haven't had the time to go to the range. I forgot to lube/oil it up before I went. And the buffer spring is very stout. First few rounds didn't cycle, but I had my brass catcher on...

Yesterday, found out that a PSA AR10 is on sale, showed my wife and she automatically said yes and that we can order one this weekend. My original goal for this summer was doing a Savage 110 .308 with an MDT chassis. Price without optic would've been north of $1400. My wife was fine with it, but...

Hey everybody. I did a deep clean on my ar10 and noticed possible etching occurring on my bolt face. I’ve shot probably 500-800 rounds out of the rifle, mostly reloads. I’ve never had a pierced primer and I don’t think I’ve ever even shot a max load out of it. I did have a batch with loose...

I’m having a strange malfunction in my .308win AR10 I’ve never seen or experienced (been shooting the gun for years). The casing would get stuck so tight in the chamber the extractor on the bolt would rip the extractor ring off the brass case. I had to knock the casing out with a cleaning rod to...

I am trying to put together a more accurate battle rifle closer to DM type use concept. So far I’ve got the aero precision M5 upper and lower receiver, lower is mostly together and I plan on going to “heavybuffers” guy for dialing in my buffer weights. I have a faxon 18” rifle length gas, fluted...

I recently bought a few parts for an AR10 build, coincidently, my first. I have a decent knowledge of firearms, but not of building and assembling. I bought a Stag 10 complete lower and stripped upper, links below. It is important to note that these are left handed. I'm currently ordering a...

I used some foaming bore cleaner on my AR-10. Yes, should have read the instructions more carefully. Now I am concerned some got in the gas tube and hardened. Is there any specific tools I should get to clean the gas tube?

Hey everybody sorry for the dumb question, I just got started reloading. i recently did some .308Win load development and found 44 grains of Accurate 2495 (paired with Hornady 150gr BTFMJ 2.735 COL) ran best. Some of my brass has some mild-moderate extractor swipe. According so Accurate’s load...

I'm looking for information about the bolt, buffer, buffer spring and how they interact with each other, tuning for proper bolt cycling. Info I'm looking for: What is the mass of a typical AR 308 DPMS bolt assembly? my bolt is 17.5 ozs What happens if the buffer mass is increased? Will this...

I am not trying to start a never ending internet war here, merely trying to ascertain the inherent qualities of each platform. If you had an AK and an AR with the same: Barrel (length, quality, manufacturer, profile) Chamber (for example, if both rifles were chambered in 5.56 NATO) Trigger...

I've gotten an email recently from POF in regards to my 308 I bought from them 6 months ago, with an offer to "upgrade" my chamber to the new design. I do reload for this rifle and what I'm wondering is have any of you noticed any adverse effects to cases with this chamber? On one hand I...
