I finished building my first lower receiver a couple of weeks ago and added a PSA SHQ 13 stainless steel 16in upper that includes a 13.5" SQR Hybrid Free Float rail. All told, I spent about $875 putting it together. After feeling proud of myself for completing this task without marring up the Phase 5 lower much I decided to take it to the range. So, I grabbed 10 rounds of black hills 69gr OTM, 10 rounds of HPR 60gr VMAX, and 10 rounds of HPR 75gr BTHP and a box couple boxes of hand loads and PMC 55gr fmj. I setup at Charlie Haffner's rifle lane and used about 5 rounds to sight in the gun and 50 yards and the preceeded to shoot 5 rounds of black hills 69gr at the target setup 100 yards out. Looking through the scope, the group appeared to be just over an inch in size. Things were really tight .5inches or so till the 5th round. I shrugged that off and loaded up 5 rounds of 60gr HPR. Those seemed to group just under an inch. Then the 75gr HPR. Ugh.. That was easily 2 inches or more. So I went back to the black hills and fired my remaining 5 rounds. What?? 2.5 inch group? Really? Fine... Time for the 60 grain. 2 inch group. Now I am feeling frustrated. I try some of my hand loads. 77gr nosler with 23gr ar comp. 3 inch group. Completely frustrated and flustered, I pack up and go home. There I give the rifles upper a good cleaning, and continue to do so till the patches come out quite clean. I also replace the springs in my QMS trigger with JP springs and bring the trigger pull to a crisp, clean 5.5 lb pull. The following week, I hit the stones river range on Friday (yesterday), after work, and preceed to shoot some more. There, I noticed that my first group with the 60gr vmax were just over an inch, but by 30 minutes, I am shooting hand loads and pulling 3.5 and even 4 inch groups. 4 inches with 5 Tula rounds, just to see. Now I am quite frustrated and feeling it may be time to dump the upper or contact PSA and ask them for some pointers on what I might be doing wrong. I pack up my rifle and noted that my hand guard was warm to the touch. At home I give my barrel another thorough cleaning and as I am cleaning it, the warm hand guard continues to wheedle at the back of my mind. Saturday morning (today) I wake up with an idea and a mission. Being an IT guy, I know that computers that heat can do weird things to electronics, and usually one can identify heat related issues by noticing that computer performance degrades over time as the PC is running. Pllying this to my rifle, and with a bit of googling, I began to theorize that my stainless steel barrel is likely more susceptible to performance degradation than my Sig M400 enhanced chrome moly chrome lined barrel and that this is the reason for my performance issues. I pack up and make a trip to mount Juliet, were I pick up some match grade ammo at Academy and Reloader's Bench and head back to stones river to test my theory before I dump my upper. Sitting at lane six, I un-case my rifle, line up my various boxes of ammo and setup a stopwatch on my phone. My plan; shoot 5 round groups, however, to test my theory that heat has been my issue, I will let the barrel cool for 30 seconds or more after 3 rounds and then fire the remaining 2 rounds. First three rounds I sight the gun in with the third round nailing the bullseye. Now for the black hills. 5 rounds at 50 yards (windy and I wanted to minimize its affect on the rounds) .43 inches. Double that and we are still under 1 inch. NICE. Next up, HPR 60gr vmax. 5 rounds, .45 inches. WOOT. Then the HPR 75gr. 5 rounds 1.6 inches. YIKES! Alright, now for some of the new stuff I just picked up. Hornady 55gr vmax .56 inches. Not terrible, not great, but acceptable. How about the 75gr Hornady vmax performance (the slower of the two on the market). .49 inches. Sub MOA. Since my goal was sub MOA, I am pleased. PMC precision 75 gr, this stuff is expensive at $1.5 a round. .96 inches. Crap! Finally, my 69gr hand loads with 25gr BLC2. .38 inches. What?!? Excellent! So, lesson learned. Pay attention to the heat when precision shooting. Sub MOA AR for sub $1000. I am pleased and I haven't even started load development. With some luck/patients and methodical attention to detail I summize I can dial this down to nearly .5 MOA. tl;dr - let the barrel cool more often when shooting my new upper and I will get rewarded with sub moa groups, which was my goal.

Glock 22, gen 2. Bought 19 years ago or so. I still own it. Almost sold it over some ftf issues. Turned out the magazines polymer near the feed lips was splitting and not feeding the ammo right. Anywho, I have debated selling it since I just bought a gen 4 in OD green. It is in pretty good condition. I may also hang onto it to hand down to one of my kids. Sent from my iPad using Tapatalk HD

I pretty much buy ammo from either Shooters, in Nashville, or I pick it up online by watching gunbot.net, slickguns.com or gun-deals.com. Between those three sites, I have always had enough ammo to shoot my AR15, 22lr and 40s&w. I just save up for a few months and then buy in bulk. I also shoot nearly every weekend so I use up what I buy. Sent from my iPad using Tapatalk HD

I bought one about a month ago. It is quite pleasurable to shoot. Worth every penny. Sent from my iPad using Tapatalk HD

Not saying I agree, but this kind of Passive expressing of ones rights is how the left has made so many in roads into our society. Sent from my iPad using Tapatalk

I agree with the AR recommendation. I would look at maybe an upper in .300 blackout, though, there are a lot of different calibers. Carbon fiber lowers can reduce the price and weight. They can break down to be carried in a backpack. I have seen complete aluminum lowers for $250 or less and complete uppers for $550. Watching for sales, it should meet nearly all of your requirements. Sent from my iPad using Tapatalk HD

:-). Now, you mention the mob turning violent, that is a different story. But yes, I think we will have to agree to disagree. I have no problem calling them rioters, but I cannot justifiably call them terrorists unless they start committing atrocities against the innocent. Sent from my iPad using Tapatalk HD

Be upset. Glare at them, call the police on them. Have the police Arrest them for violating the various pedestrian and vehicular laws that we have, but do not call them, or treat them like terrorists. Israel has to deal with terrorists. What we have is simple civil unrest. Sent from my iPad using Tapatalk HD

I cannot disagree more. It would be wonderful if more groups would simply gather on the lawn of whatever government capitol they were near and protest there, but peaceful civil unrest should not be met with violent response. I would hope that no medical emergencies are not at risk due to a protest, if every decision we made was measured against the stick of 'what would you do if your significant other' was used, then I see our freedoms quickly eroding in the face of personal security. However, I think we have strayed far from the topic at hand, and for that I apologize since I did bring this particular soapbox into this thread. Sent from my iPad using Tapatalk HD

Sorry, but according to the FBI definition of domestic terrorism, this fits right in. First thing that stands out is the intimidation part... Sent from my SCH-I545 using Tapatalk 2 So where do you draw the line on what constitutes intimidation? If violence or the threat of violence isn't involved, can it be domestic terrorism? If so, can drones be used to take the intimidator out? What about using a sharpshooter to put down the leader of a protest that threatens the local economy for a day or two because they have amassed in the streets? Could that be viewed as intimidation and allow the use of lethal force? Sent from my iPad using Tapatalk HD

Build your SBR as a 300 blackout. 9" barrel performance appears to be not that far off from 16" barrel and seems to have been made for SBR. http://en.wikipedia.org/wiki/300_AAC_Blackout_(7.62×35mm) Sent from my iPad using Tapatalk HD

I am in no way supportive of OWS and I agree with the juries decision on the Zimmerman case, but please do not try to confuse or equate OWS actions with Terrorism. In no way are their actions anything close to those of suicide bombers, 9/11, Ted Kaczynski or Timothy McVeigh. The more we loosely use this term, the more power we give the government to abuse this term to attack its own citizens. Just google domestic violence and terrorism and you can see how this term can be misused. Civil unrest should not be confused with terrorism, that becomes a very slippery slope and a double edged sword. All I have to say on that. Sent from my iPad using Tapatalk HD
