    AR Pistol build deets, good to go?

    Putting together parts for a pistol build. Primarily for fun range time (so will get shot a lot likely) but will travel with me for long trips. I haven't parted together an AR before so thought I'd run these by you guys. Not looking for a budget build or top of the line, just nice and reliable.

    Aero M4E1 threaded receiver set
    Odin Works stainless 7.5' .223 Wylde w/adjustable block
    Trinity Force FW II keymod triangular rail 9"
    Linear Comp
    WMD Nickel Boron BCG
    Geissele SD-3G trigger
    Law Tac folding adapter
    SBA3 brace
    Ambi Safety
    Extended mag release
    Extended pins
    Armaspec charging handle
    Magpul Pro MBUS
    Slim Grip
    Vortex Sparc rds

    I understand 7.5" barrel ballistics and will be working up loads for this rifle. Other than that, any issues with the above I should be aware of?

    Install a Colt or Sprinco M4 extractor spring.
    Take a look at the BRT Covert Comp. It's smaller, lighter and costs less than the Flaming Pig and it works.
    Get a Split Fix for the SBA3. The Split Fix will stiffen and protect the rubber wings. It's well worth the $25 cost.
    I think the Sig Romeo 5 is a better econo RDS than the Sparc.
    INSIDE PLAN OF BOX
    1. ROAD-RUNNER LIFTS GLASS OF WATER- PULLING UP MATCH

    Thank you for the tips! checking them out now. The Sparc has been sitting in the closet looking for a home for a few years, lol.

    I would skip the nickel boron bcg and go with a quality bcg like BCM or Colt. If you're looking for one that's coated look at NP3 instead.

    Hmm, I read through a ton of posts on here as well as other reviews and the WMD was rated within the top 5 BCGs for quality. Am I missing something about WMD?

    Here is one of several threads on the topic of nickel boron.

    So, it's done. Got it out to the range and was getting 3mos with a 2moa dot. No keyholing and was getting ~2250fps using .223 Hornady black 75grn. Tbh, I was pretty surprised at that. I expected some tumbling and in the 2100 range. So def happy there. No failures. The aftermarket pins were slightly undersized and the receiver had a little wobble. Fixed it with the Aero tension screw.

    The SD-G3 Trigger is amazing. Very very happy with it. I think the only low quality parts in there are the trinity force handguards.(Please correct me if I'm wrong). I'm going to switch those out for a shorter m-lok rail of better quality. First build so didnt really know what was best for some of the parts. All in all, I'm quite pleased. I need to take it out to a longer distance range with an LPVO and see if it can hit decently at 200-300 yards.
