    One of these days I may ask for some help building an AR, since you live in So Cal.

    Thought I'd toss this out there, but is there a reason all these piston retrofit companies need to be installed by a certified whatever? Take the PWS for instance. It appears to me all you have to replace is your carrier key, gas tube, and gas block and put the system together. It's not rocket science or am I mistaken?

    I thnk it's because a lot of the kits that are advertised as "drop in conversions" aren't, and maybe because some of these companies want to cover themselves against claims of damage to the rest of a firearm even if it was bubba messing up the rifle.

    Technical question:

    Pistol grip assembly... Am i right in thinking that the bolt and threaded hole is standard across all AR-15 manufacturers?

    If it is MilSpec............it is. Not knowing 100%, I would say it is standard. There are a lot of new manufacturers, so can not say 100%.

    when i installed my MIAD grip, it told me i had to use the included screw. ive tightened it down, but the grip is still wiggly. im half considering taking it off and putting the A2 grip back on.

    Different pistol grips can use different length bolts depending on the amount of plastic in the base of the grip. But if they included their own bolt, it doesn't make sense that it wouldn't tighten down properly. Hmm..

    I just put a MIAD on my LMT, the bolt works fine, but I had to shave a bit off the inside of the grip to get it on there, just plastic so no big deal. Getting the trigger guard pin out however was a nightmare. LMT uses some tight ass pins, had the same problem with the rear sight when I replaced them with Trijicons. I was even using the correct tools!

    All thread size are the same, it is spec.

    But a lot of the grip mfg include a separate screw due to the different interior grip chamber which might require a slightly different grip screws.

    Got a question for you AR gods.

    i want to shorten my AR from a 20 inch to a 16. instead of getting a new upper(which i can not afford), i was thinking of keeping a my Rifle length rail system, and getting a new barrel, new gas tube and a low profile gas block and just have some like 4 inches of barrel stick out. how feasible is this?

    It's very feasible. I'd recommend looking into mid-length gas systems and barrels. Plus, make sure to gauge your everything after you do this. You may also need to change your buffer for optimal performance, but I'm not sure on that.
