    18" BCM rifle upper - range report

    Man, I love BCM's work.

    42-52 degrees. 70% (est.) humidity. Wind from behind a 3 mph full value.

    Ammo is handloaded 69 gr SMKs, 24.5 gr RE-15, LC brass, OAL 2.255" and Tula SRP.

    Distance: 100 yards

    This is my first group out of the new rifle, had to come over 2 mil, hence the 8 shot group with the 2 outliers:

    Here's the second group, still need to come down ~one mil:

    .86 MOA over 10 rounds with only 20 down the tube, and with a std. SSA as the FCG and me driving. Gotta love it.

    Shot the dot drill next (1/2" dots), and did pretty well (for me):

    Now to do some load development and see if she'll really shoot!

    Cool!

    Which 18" upper did you get? I got one of their 16" SS410 uppers to scope up as a "precision" AR, but haven't had a chance to set it up yet. Grant recommended it, said they're real shooters.

    Awesome results man, and great shooting.

    My 18" BCM SS410 is turning out the same type of tiny groups.

    I bought this one above. I'm not a fan of stainless barrels in the white, but it's nothing that a little Gunkote won't fix. I'm really liking the TRX rail so far, when I was unsure of it before I ordered.

    I also have a BCM Ionbonded 16" SS410 that I put an Omega rail on.

    It'll shoot round for round right along with the 18" above, but it's harder for me to drive the way it's set up right now. My best group of 10 using 77gr SMKs was .69" CTC, but it averages .97" over 20 averaged 10-round groups, with me doing the shooting as the limiting factor. Here's an example I had on file here, the vertical stringing is all me:

    Excellent. The 16" I bought was with the 11" TRX. Looking forward to getting glass on it and seeing if it'll shoot.

    Great photo as well!

    Thanks for posting this. I got the exact upper you have for Christmas and just this Friday had a chance to shoot it with a scope mounted. I didn't get the accuracy results that you did, but I'll be the first to admit I am most likely the limiting factor. Shot both Black Hills 69gr OTM and Prvi 75gr OTM with the BH shooting just over 1 MOA 5 round groups and the Prvi right around 2 MOA.

    What kind of mount and optic are you using?
    “The ruling class doesn’t care about public safety. Having made it very difficult for States and localities to police themselves, having left ordinary citizens with no choice but to protect themselves as best they can, they now try to take our guns away. In fact they blame us and our guns for crime. This is so wrong that it cannot be an honest mistake.” – former U.S. Sen. Malcolm Wallop (R-Wy.)

    Larue for the mount, think it's called their LT-104.

    Weaver GS Tactical 3-10X40 for the optic (Midway for ~$299). It's a good budget optic, IMO while your saving up for better glass. It passes the box test and the glass is pretty good for the price.

    I'd skip the Privi for serious accuracy.
