The AR15 Picture Thread

Shoots a lot of groups like that. 16” Douglas barrel bought used off here. Black hills 77tmk

First off, nice MARS! Second, how did you get the TMKs to shoot so well in an AR?
Don’t know they do well in this barrel. Got lucky I guess. Thar was the only group I shot with it that day. Confirming / re zeroing after lending that scope out at a gas gun match.

PSA 75 black tip and AE 50 tipped both went into about 0.8” but I was shooting fast just checking where they land when zeroed with tmk.

Tmks kill great. Better than anything I’ve used

Yeah, you never know with barrels what they will/won't like. I'm just surprised about the TMKs as it seems like they just struggle in ARs for some reason. I have a number of precision oriented .223s that shoot 77gr SMK/Scenar/Berger OTM just fine, but won't group for shit with TMKs for some reason. Out of bolt gun they seem fine though.


It feels wrong to blab in a picture thread, so here's my wacko contribution...

No one in Service Rifle uses TMKs during Rapids for a reason. The tips get banged to crap.
That really goes for any polymer tipped bullet. On the 600 yard line where you are single feeding them and pushing them into the chamber, sure, but not feeding from a mag.
 
Polymer tip bullets are exponentially more deadly than fmj/smk/so/etc

Been shooting them a long time. Haven’t had trouble hitting things / grouping
Just giving the problems service rifle shooters have had with them. 77 SMKs seem to do alright on animals. If there was an accuracy advantage with 77 TMKs the AMU would be using it on their SR team. Right now I believe they use 75 VLDs across the whole course. I’d have to check up on that though.

Very nice.
To this very day, you still can't go wrong with a good ol Mk 12. Even though I know in .mil their role has largely been taken over by M4 Block II's and URGI 's... And the M27 IAR/M38 DMR in USMC.

Actually considering doing a NSW Blk II DMR clone ala the picture below, but with one of Centurion's mid length gas SOCOM profile barrels.

eOriginal Secret Service used KAC SR16 uppers (URX2 and URX3.1) with KAC NT4 silencers on KAC SR15 SBR lowers:

Man @USMCSGT0331 your posts of your collection never disappoints sir 🔥😍

On the IAR prototype and the clone built from a 6921...
What are the differences, if any, re: barrel specs, contour, etc?
They Colt IAR contender was still DI operated , no?


Apologies for all the back to back posts...haven't visited this thread in wayy too long!

Do it all 0-600m rifle.

11.2" Larue Stealth Barrel
Medium KAC FF RAS
KAC QDSS-NT4
Vortex PST2 1-6 Mrad

I slept on the PST2 since its release. Holy hell is it amazing for the price. 80% of the razor at 30% the price. Only gripe is I wish the illumination went up one more setting. 10 on the PST2 is about like an 8 on an NX8.

2500fps with 75gr ammo and a 36/200m zero. VMR2 reticle is good to 650m.

Sorry bro, couldn’t resist the joke. Love the build.
 
Nice !


More details ? Barrel length ? Velocity ? 223 I assume

Thanks man! It's an 11.3" 223 Wylde chamber, only put a few rounds through it to function test so far. Will get out next week to do some accuracy testing with 69, 75, & 77 grain ammo I have on hand & plan to chrono it then. I will say that it functions flawlessly so far with just an H buffer & standard carbine spring. I received a Sprinco "white hot" buffer spring in the mail a few minutes ago for a little extra insurance since it'll be run suppressed with heavy bullets 99.999% of the time. I'll definitely follow up when I get it back to the range Monday or Tuesday!
