    for those that assemble their own ARs, what's your favorite custom small parts kit?

    When I assembled my first AR years ago, it seemed lower parts kits were lower parts kits and besides triggers there wasn't a ton of other parts that were not "mil-spec" or something claiming to be.

    the big thing then was triggers and ambi safties. and charging handles.

    so for your builds, what do you like for all of the small parts.


    for me I like ambi safeties. I always preferred the b.a.d - c.a.s.s with a full size on one side and short throw on the other. I see a lot of people stepping up and going for the talon now but realistically there are so many I'd wonder what options people picked.

    I've tried different mag buttons. not many. I prefer the mil-spec stuff.

    I have 3 different charging handles. raptor, geissele, and the BCM with he large catch. I prefer the geissele

    I like the vltor a5 buffer system

    I haven't gotten into different bolt catches.

    I do like slightly longer dimpled takedown pins. especially because some of mine are so tight I need a tool to pop the pins.

    and I generally have all colt pieces for the pins and springs and all that.


    so what's your go-to setup for building out an upper and/or lower?

    Pricewise I like the Sons of Liberty kits w/o grip or trigger. If Iím feeling spendy itís the Geissele Super Duty for the Maritime bolt catch, ambi saftey and coiled roll pins. but since a buddy loaded me up with coiled pins and I donít consider ambis a must-have, I usually go with parts on hand. I like a couple of the self-locking castle nuts, but again pricey and standard stakers are fine. A5 on 90% of mine. A couple standard tubes for length and nostalgia.Those dimpled takedown pins are nice. With you on charging handles.Have a couple Larue 2 stage though prefer G SDC and E.

    If I could start over all my stocks would be LMT Sopmod or Magpul SL. And all BCGs LMT Enhanced or Sionics NP3.

    A lot of new, good-idea small parts Iíll try, ( especially Rogerís) but costly individual parts add up quickly.
    Iím too lazy to take off all the cool custom parts to put on one gun. Going to be long, cold winter though so ...

    I haven't purchased a complete LPK in a long time.

    The way I usually put together a lower parts kit:

    Fortis or Battle Arms Take down pins... have been buying more of the Fortis ones lately.
    Radian Selectors... I think their design is the best on the market. I will still buy Fortis ones as well, depending on if I'm buying pins.
    Forward Controls Bolt Catches
    Triggers... CMC, Geissele, Centurion Arms or ALG Mil spec triggers.
    Magpul MOE Grip
    Mag release assemblies, I'll just buy locally from Rainier.

    I go with Forward Controls for most lower parts.

    -Mag Release Button
    -Mag Catch
    -Bolt Catch
    -Take Down and Pivot pins
    -Springs and dents which are KNS

    Triggers are usually G but I do have a Centurion Arms 2 stage that I havr installed yet.

    Safety is usually Radian Talon. But FC has many options

    Another reason I sometimes go with the Fortis, I like their 50 degree. Usually I go 45 on the Radian, but the Radian has cuts for 90 and 45, so you can change it up.

    I have a variety of stuff and like it well enough that nothing screams to be changed. Geissele SSA's in every rifle. Raptors on all but the KAC. BAD levers/talons for selectors. FCD bolt catches, mag buttons, and a couple forward assists. The Radian is all Radian, and the KAC is all KAC except for the bolt and barrel. Springs, detents and roll pins come from who cares because they're like rabbits.

    Aero Precision LPK minus FCG is my starting point. Geissele trigger, BCM Gunfighter grip, trigger guard and CH. I tend to use Ergo grips for bench guns. A few ambi controls on certain rifles. I have the Radian ambi safety on one build largely due to recommendations from this forum, but honestly I prefer the ambi on my LMT. If I'm really going to be swapping out a lot, I just by the specific small parts I need from White Oak Armament.

    I mostly use WOA for all pins and springs.

    Havenít bought a ďlower parts kitĒ ever I think

    Use to think the NAD was the best safety setup.. nope.. turned onto the talon and want more of them. Just there shorter arms are better at staying out of the way..

    Triggers , G or Larue mbtís right now

    Fcd bolt catch on one, nice but $$$
    Fcd mag release buttons are the best Iíve used so far
    Buffer systems , variety std spring and H2ís work all day, but tying one of the armaspec srs setups.
    Looking at trying a A5 setup also..

    I need to try an H2 and see what all the hype is about. I have all standards in my small frame guns and they work fine. Is it for softer shooting? Suppressed, rapid fire?

    JP Trigger (comes with a safety)
    JP SCS
    Forward Controls Bolt Catch
    Forward Controls mag. release button and spring with BAD mag. catch
    Forward Controls FA or V7 Minimal
    Raptor CH
    Steel Safety Detent w/ Sprinco spring

    Iíve tried most of the G triggers, Trigger Tech, Hiperfire, CMC, LaRue... JP torches them all. Only other one Iíve tried that can touch it is the Elftmann, and the one I (temporarily) had was a total POS.

    JP torches everything again with the SCS. I like it even better than the A5 system. Softer, smoother, flatter muzzle, never noticed a difference in reliability. That with both the standard and Green spring. Same goes for standard length system with carbine - H3 and Griffin SOBís with everything from standard carbine to Blue Springs and Flatwire.

    The combination of the BAD mag. catch with a Forward Controls button is nice and sits below the fence. Stiffer spring gives a more quality feel.
