    I'd like to hear more about the Cav lower, if you have the time and don't mind PMing me about it. The new manufacturers torture test video is interesting, but I always prefer 3rd party experiences to manufacturer claims. This will not, however, be a duty rig, and it's very unlikely that any lives will ever depend on it.
    My gen 2 Magpul mbus front sight is under an ounce.

    The cav lowers both spilt near the rear take down pin with fewer than 100 rounds on each. One had a 6920 upper, the other an LMT 16" carbine upper.

    If there have been revisions to the cav arms lowers through substantial structural changes and/or a polymer reformulation, the new ones might have merit. If not, I see them as .22lr only.

    That's interesting. Given the torture test they showed, I wouldn't suspect that, but I may have to consider other options. Thanks

    This was almost two years ago. If they have improved stuff, I'll give em a shot. Just wanted you to go in with eyes open.

    They posted it earlier this year. I haven't seen anything saying they changed the FRN material or manufacturing techniques since GWACS took over though.

    If it was going to split though, I would think running it over would have caused that. The weld method they use should make it virtually one piece of FRN.

    Other barrel options

    Interesting - I've never looked for a basic 18" upper, so I was surprised to see there's nothing out there like that.

    Just throwing out a couple other barrel options for you to build up or have someone else do the build.
    Brownells has 18" FN CHF barrels for $300 (link) and Criterion 18" rifle barrels for $269 (link)

    RifleGear has 18" FN CHF barrels for $289 (link). Rifle gear may be able to build the upper for you with a FSB installed and their prices and services are similar to Rainier in my experience.


    Otherwise here's a similarly priced option to what you would pay for an 18" FSB upper - use a 18" barrel with a lopro gas block like this one for $180 with gas block (link), put on a ALG, Midwest Industries, or Troy rail for $150 (Primary Arms has Troy rails for about $120), give or take. Then you will be at the same price because of the $180 barrel with block vs $300 barrel + FSB + gunsmithing. Weight difference will be negligible, as has already been stated. You could also build that yourself, only special tool you would need is a barrel nut wrench (maybe not even that - depending on the rail you select, because the options I mentioned come with a wrench).

    Excellent options here.
