    Question Critique my Build

    I'm making this post in an attempt to acquire knowledgeable and accurate criticisms about my build and what I can do to greater improve it's overall effectiveness & reliability in a life & death situation. I don't plan to argue or defend my points so feel free to post accordingly, and if you don't see a reply from me just know that I am actually reading your responses and learning form everyone input.

    The Purpose
    While it's 'primary' purpose is aesthetics, I've done a bit of research to make it as functional as possible. I would like it to be able to run in an SHTF situation as well as a home defense scenario. The added bonus would be it's capability to perform in competition and hog hunting. (both of which ive never done but would like to get into)
    Ultimately, I would also like it to last should a time come that I'm able to run thousands of rounds monthly if not weekly.


    With that said, the following is what I have setup as the AR that I'm building in it's complete form:

    Core Parts
    Flash Hider - AAC Blackout Flash Hider (Pinned & Welded)
    - 14.5 Centurion Arms CHF Barrel Carbine Gas Length (Pinned & Welded)
    - Centurions Arms Low Profile GB (Pinned)
    - 13.5 Centurion Arms CMR Modular Rail
    - Carbine Length Gas tube
    ----
    - Parralax Tactical Upper Assembly
    - Fail Zero BCG (was planning to go Centurion Arms BCG but it was sold out )
    - BCM Gunfighter Ambi Charging Handle
    -----
    - Seek-ins Precision Forged Lower
    - BAD-ASS Ambi standard Selector Switch
    - Magpul Miad Grip
    - Weapon Outfitters H+ Buffer
    - Sprinco Blue Buffer Spring
    - DS Arms Mil-Spec Buffer Tube
    - Noveske QD Back Plate
    - Spikes Lower Kit (plan to change trigger to Geissele SD-C)

    Attachments & Other Parts
    - Magpul CTR Stock
    - AImpoint T1 with LaRue Tall Mount
    - Aimpoint Flip Magnifier with LaRue Mount
    - Magpul MBUS Pro (front and back)
    - Surefire Scout Mini with Drop WIng mount
    - Magpul Handstop

    Misc.
    - D-fender Extractor Spring

    Get a 16" barrel. You'll thank me later. Go for mid length gas as well.

    Consider a Raptor over the BCM ambi charging handle. I love the Raptor, as do many many many people.

    I'd save money and get the magnifier last, and learn to shoot with your red dot without magnifier. You may realize you don't need it, like many people including myself have. Same with the handstop.

    The only reason I got the 14.5 was because I heard centurion arms was amazing and 14.5 was the only ones available at the time I made my purchase. However, I definitely hear you on the 16 inches.

    With that said however, what kind of problems I can expect out of going pinned and welded? And would it be detrimental to my survival in SHTF or home defense?

    As far as the Raptor is concerned, I really do want one and it was what I wanted originally. (its actually what i had on my old built) i just went with the BCM this time around to try it but if you can give me additional details as to why I should go for the raptor that would help me a lot.

    16" gives you a bit more velocity which means longer effective range in which fragmentation can more reliably occur. The 1" difference you won't notice at all. It also lets you run a mid gas tube which arguably shoots smoother. Longer barrels are also slightly quieter.

    If you want a gun you can depend on in life or death, get a Colt, KAC, Noveske, DD, BCM etc, put an optic on it and buy ammo and training and go shoot it. Then based on your experience actually using it, decide what to replace or improve.

    Just a personal thing on the rail, I'd go with a Noveske NSR, the new Midwest Ind Keymod, or the upcoming BCM Keymod. I think they look better and are lighter.

    For the Bbl, I'd recommend a mid length gas 14.5" or 16".

    I don't think you should necessarily set your heart on a Centurion bbl, they're about as good as anyone else but I haven't heard anyone praising them above anyone else.

    For your charging handle, this is really just since aesthetics was one of your goals, but perhaps get the Raptor

    For the grip, the MOE K2 is getting released soon, maybe look into that. Functional and pretty aesthetically pleasing.

    For your stock, have you perhaps considered an Vltor IMOD? The clubfoot or regular version, either one. With the IMOD you get a better cheekweld and also storage, in exchange for a scant .05lbs addition.

    I don't have experience with this, but I've heard a lot of people pulling away from the RDS + Magnifier build. Apparently the off axis weight of the magnifier is a bit annoying. Maybe look into something like a Accupoint 1-4 if you want the zoom?

    Ah I see. For now it's too late as far as getting a 16 (much of the upper I already bought) but I'm considering getting an upper with a 16 inch in the near future anyways in the case I need to make use of those advantages.

    @Renegade
    I'll definitely take that to heart. Though I am curious, how far can a 'Frankenstein' build go as far as matching a 'top tier rifle' made for the same purpose in mind?

    It definitely makes sense that a fully built rifle would be better in general since all the parts would be spec'd and measured accordingly as it is assembled. What I'm curious about is if a custom built rifle could ever match a complete one given that both of them were constructed with the same purpose in mind.

    @Hygienist
    I do have some parts that I haven't purchased yet and I'm sort of borrowing accessories as of now to test and see how the upper runs.
    I'll definitely put all those things into consideration as I near the completion of my build.

    I would honestly save the money on the FZ BCG and go with a milspec BCG. I own a WMD BCG and I can honestly not see or feel the difference. Cleaning is about the same, not to mention that the finish stains.
    I would also run the H2 buffer with the blue Springco. It's reliable and runs all types of ammo from my experience.

    Goodluck

    Ehh... i kind of regret it myself. I hope I can return it but given that I've shot 100 rounds through it already I don't know if they'll take it back X_X

    If I have to keep it, then I'll just make due and make that choice to go for something else with the 16 inch mid-length upper i have in mind.

    Parallax Tactical also makes a keymod rail that is very similar to the NSR.

    Seriously? We are talking about Centurion Arms, right? You know, the company that machines their CHF barrels from FN M249 blanks?
