So not your standard mil spec rifle.  (I'm not a huge AR guy so I'm thinking, $450 upper strapped to a $100 lower, built with a $60 parts kit...) :chuckle: :chuckle: :chuckle:

Maybe "Mil Spec" wasn't the wording I was looking for...."Budget" AR may be more descriptive.  Again....my 20" heavy barrel varmint rifle was capable of sub MOA.  Just trying to figure out what I should expect.  I love reloading, I love bolt guns........I don't love AR's.
”budget AR” and “mil spec” is the same thing. The lowest bidder wins the military contract so it’s always budget. Lol

I do not necessarily agree that budget AR = Mil-Spec.
The Colt M4 Carbine CR6920, or the FN same Spec, are battle proven dang good rifles.
There are a few ton of “budget ARs” that do not stand with Mil-Spec Colt or FN.
I will say there are also allot of decent rifles below the $1000.00 price range. And many manufacturers have improved their ARs to be equal or better than the Colt and FN, in the same price range.

Ya I dont see the connection between "mil spec" and "budget" as one is not indicative of the other.

Nice shooting!

Weekend before last I was shooting at the 100 yard range, when I glassed my groups I could not help but notice two lanes to my left someone was hitting sub-MOA.
I looked left and saw this gentleman at least my age if not older, shooting “off hand”  :yike:
I have met most of the shooters that hit this range. I had ever seen this gentleman.
I watched his hits through two 20 round mags. If it were not for two flyers, he would have had 40 rounds sub-MOA.
I waited to talk to him. He was ex-Army Delta (in the 80s-90s, shooting a Danial Defense WPSM4A1 Signature Series, with a Steiner M8Xi 1-8x24, A $4k scope!
I have shot the Steiner 1-8x24 twice, probably the sweetest variable scope I know. Also extremely expensive.
It is rare to see a true master of his craft shoot. This guy never had his rifles touch the bench. I was amazed, mostly because I have been a believer in off hand shooting, because this is the how you or I will be shooting in a real life scenario.
I practice all the time under 50 yards, with multiple targets while shooting and scooting. And hate to admit it, but the eyes just aren’t what they once were. And at one time I was very good at CQB. Seeing a guy my age still shooting like that was. Really nice to see.

Worked up three loads and went to the range today.  Shrunk that initial group by over half and am shooting sub 1.5 MOA.  One of the groups was right at or under 1 MOA.  It appears the gas gun likes a little less velocity.  May try a tuner brake to see if I can tighten it up even more. 

First picture is the bolt gun 16" 300 blackout shooting suppressed 5 shot group, 2660 fps.

Second picture is the AR 300 blackout not suppressed with 2 grains less, 2460 fps.

Have to post the pics from my phone....so it will take a minute or two.

 Very nice!

What barrels do you have on those?
And triggers?

It's got a Timney Impact trigger and whatever barrel palmetto puts in their uppers????   I'm not a huge AR guy, but had this one put together on the cheap to fill a void in my life.  I'm impressed with how it is shooting right now and hope to tweak it a little more to have it shooting as close to 1MOA as possible. 

I have a Rise Armament Trigger that I may try out in this rifle to see which one I like better.  The price was right on the Timney when I bought it so had to try it.  It breaks right at 3 lbs.

That is pretty good accuracy for a stock off-the-shelf PSA barrel.
