Which BCM barrel

[TXinfidel]

I'll second the 16" SS410. I picked up a 'sale' upper from BCM with the DD lite rail, puts any MK12 I have shot to shame with MK262. It is a .75MOA barrel when it is hot, and I have shot many sub .5 MOA groups with it.

Txinfidel,

Do you use exclusively mk 262? Is it your own make or bought somewhere? Are there other cartridges that do well in it?

I just ordered the 16"ss410. Should be here tomorrow. Wondering what it is gonna like.

T&E'd a SS410 16" KMR Upper and it was phenomenal. I never found a Cartridge it didn't like. It would bughole M855 @ 50m when a RDS was employed on her. Solid Sub-MOA.

Thanks HD. Good to know. That is the exact upper I ordered. I did it mainly because I was going to have a suppressor and wanted to mitigate POI shift. Wanted the thicker profile, but still lighter weight on a SPR type rifle. Had to sell off one of my ELW/KMR uppers to get this done.

Perfect choice and reasoning. This is probably one of the smartest Profiles available on an AR Barrel.

Got to take it out today. This is all suppressed, (YHM SS QD)

It really liked Freedom 55gr and Hornady 75 gr BTHP. 23.5 gr varget.

best grp




average grp m855 (wolf gold was about here too)


I only had one target. so I had to get creative...sharpie where I was aiming (on middle points between orange bullseyes).

Overall, I am happy with grps. Only problem is the shooter was a spaz.

When or if you get the chance, try some .223 FGMM 69 & 77 SMK, and funny enough, Hornady (Varmint or custom?) 55gr Vmax... those have all shot super tight for me.

I've also had good luck out of the Hornady Match 75gr BTHP .223 stuff.

Shot a .65" 5 Shot group @ 100y with BH Mk262 the other day...was really pleased with that!

These barrels (quality SS precision) normally shoot better than we can on most days!
