I have never had any issues with an AR cycling any ammo. IMHO they are not nearly as picky/fincky about ammo as folks think they are. That said I love my LWRC upper even though it is a pig.

Edit--- I prefer a 1/7 twist barell but this is a decent price on an older Bushmaster.

My Elite Car will it anything I feed it. But so will my Colt M4 6920 MP-R

I built mine. It runs any ammo I put in it, with no hiccups!

I've never had any AR not function with any type of ammo I fed it. There are many factors that come into play with any issue of FTF,FTE,etc. to just start laying the blame on the ammo.

Most shooter's that complain about having problems with an AR don't know how to trouble shoot the weapon to know what is causing the problem,and most of the time,the shooter is the cause of the problem by not knowing the How-What-When's of owning / shooting / maintaining an AR15 in the first place.

Guy's buy or build a new AR,and they don't clean and lube it like it should be. Then they don't try to break everything in,sometimes things take a while to mate together to run like a fine tuned machine.
I don't know where some of you come up with these High powered - Low powered 223/5.56 ammo things. Factory ammo is loaded to SAAMI specs in the USA,and CIP specs in other nations.
The only low powered loads would be sub-sonic loads,and they are known to play havoc in gas guns.
Even if you hand load at a loading manuals starting load,it will cycle an AR with any bullet weight chosen.

Have to agree! With over 1,500 rounds through my AR-556 of just about every brand out there, I've had zero failures of any type. It goes bang with every trigger pull. Totally reliable!

My colt 6920 eats whatever I feed it. All the off the rack stuff is good to go and this includes the Tula.

Colt 6720 (light weight) or 6920 (m4). Will eat anything---but out of respect for my 36 AR's I do not run Steel case ammo....period. Also of those 36 AR's, name brand or Mikey built with Aero components all will eat factory brass ammo and my reloads without complaint, malfunctions are not acceptable.

My Arma Lite will run any thing! But I stay with US made ammo it likes 69Gr match bullets I have shot 5 rounds that was one hole a little bigger that the bullet it self My Windham likes the cheep 62 or 64 from any made in the US The Fiocchi is the only ammo that I have ran in my Arma Lite that is not US made and it does like it very good That is how I found out it liked 69 match bullets. I have 1/9 1/8 1/7 I like the 1/8 for all around shooting I do not shoot any thing over 69Gr I do have some extra uppers that I switch out when at the range.

I have numerous AR's... none have ammo problems.

In all honesty... I had to read the OP's original post numerous times.

If your SCAR won't run M855 ammo... ( and no offense at all ) something is wrong. Seriously.

Your friends DD should also run M855 with no issues.

Again no offense, but the original post truly baffles me.

IMHO, I would get the SCAR fixed.

Are you sure the gas system isn't set to the wrong position ?
