    Nickel Boron BCG's?

    i had a Daniel Defense bolt carrier that was IonBonded and i was not impressed. i saw noticeable wear on the rails that the bcg carrier uses to ride on. it was slick and the finish was a beautiful deep black but i was surprised at the wear it received. my np3 carriers feel smoother and do...

    GAP 10 Owners Manual

    there's a one page flyer in the case with the rifle that tells you how to break it in and that's about it. i got one with mine. let me know if you need me to scan it and send it to you.

    GAP 10 Mag release

    If its the bolt release, the GAP, like the POF should use the regular AR15 bolt release. The mag release is a Norgon ambi mag release.

    i wondered how long it would take for a knock off...

    Ah, a lower is a lower. Core15 has a similar billet lower to this on. As others have mentioned, the magwell on the Seekins has a drop in the front. You want to point out the Spike's Punisher logo? There's an 80% rule I believe. There are a lot of lowers that are going to look the same, screw...

    SBR Build

    Actually, I saw a post recently of a letter from the ATF that states, if you have a stripped lower built as a pistol, then converted to a rifle with the appropriate lenght barrel, you can later revert it back to a pistol and it would be legal. Would I recommend doing that? Probably not, that's...

    Dedicated .22 AR upper for SBR?

    I have 2 spikes uppers, one 5.5" cut down by Adco and one 16". It took a while to break in the Spikes upper and get it to feed well with different types of ammo. You kind of have to play with polishing it and the springs. Also had a firing pin break on me and it wasn't bc of dry firing either...

    Looking to build a MK 12 Mod 0

    you will need: PRI tubular handguard rifle length (we're limited to the GenIII's now, the original one is too hard to find) PRI flip up gas block front sight (the original front sight had set screws i believe, and an easily adjustable sight) ARMS top rail (PRI makes a great copy) ARMS 40 rear...

    Umbrella Corporation AR-15 uppers and lowers cheap!!!

    also, Aero's cheaper lowers are the "blems". i bought a regular one at full price ($200) and it looked like someone dropped it. very disappointed in the QC. also had a lot of machine marks. i guess mine should have been labeled a "blem"

    AR15 Platform....which brand/model ?

    the HK is HEAVY. but i won't lie, if you gave me one, i'd take it, but for that price range, i'd rather buy a Knight's or Noveske and still have money left over for glass.

    300 blackout not cycling

    i think the subs were designed to run w/ a suppressor. are you running it suppressed? supers will probably cycle it. but i agree w/ everyone else, it's the buffer.

    Umbrella Corporation AR-15 uppers and lowers cheap!!!

    there were definitely more than 100, i had 2 of them. they have had 3 runs, the first one, the color fill version (done by Mega), and the last one w/o the safety/fire stops. i do not believe they do it in house, i believe they design in-house and then have a vendor mill it.

    KAC LPR barrel contour

    you need a barrel that has a little lip for the collar. i think you may have to get your barrel turned a bit. i would send it to ADCO if it's necessary.

    Umbrella Corporation AR-15 uppers and lowers cheap!!!

    you have to take into account UCWRG doesn't have their own mass manufacturing. they outsource it and have vendors. so their prices are going to be higher b/c they're buying machine time on someone else's equipment (MEGA) and that slows down someone else (MEGA) from producing lowers.

    First build 9mm AR question

    You don't need the spacers/quarters if you have their ST9x buffer, it's longer already.

    First build 9mm AR question

    Try a heavier buffer, or adding one of the Spikes 9mm spacers, and a stronger spring. It could have been a bad heat treatment on the bolt catch. But either way, either a 9mm buffer (longer and heavier than a standard carbine buffer), or a heavy buffer with the 9mm spacer (or quarters...
