    Bought a stripped lower for $50 from palmetto state armory. Need suggestions for some parts that are budget minded but quality. Some of my wants are:

    Extended rifle length free float tube.
    Chrome lined barrel.
    Flattop receiver with m4 feed ramps.
    Solid adjustable stock.

    I am not about having names to list off when describing my weapon so long as i know the parts are quality and will function when the time comes that they need to. I really am looking for sone direction on what i can skimp on and what i need to pay top dollar for. As well as some sources in which i can find reasonable prices and good service.

    Well brother , there are some quality parts out there that don't break the bank
    1-Diamondhead rails are nice and run $150-20
    2- FN makes a nice chrome lined barrel for around $200
    3- Magpul makes nice $50-65 stocks
    4- Aero Percision makes a upper for $80 to 100 based on if it's stripped or comes with port cover and forward assist. Of course there are cheaper components but then you get cheaper quality product. I think these parts are good quality and on the cheaper side. They are name brands but the cheaper ones on the spectrum.

    I bought an AWESOME upper from PSA and got it a few days ago. It was something like this
    http://palmettostatearmory.com/inde...um-ss12g2-without-bcg-or-charging-handle.html

    CHF, chrome lined and all the specs you mentioned with Kmod rail which I love. I paid about 350 for it and am thrilled. Looks and feels very solid. There is also this
    Therhttp://palmettostatearmory.com/index.php/psa-m4-strikefire-premium-black-friday-upper.htmlis

    I would take a week or two and check PSA every day for their daily deals. You already have a good start with their lower. He'll I saw a deal the other day where they had a complete upper and complete lower that totaled around 450 when bought separately.

    I also bought a BCM gunfighter and spikes BCG and love the whole set up. Gonna start a lower soon.

    I personally like a mid length , but thats my personal preference . Carbine length has been around a long time and ran flawless for a long time. Saying that out of the 9 ARs I own all are carbine except 1 .

    16"-18" barrel midlength is best.

    18"-24" barrel rifle length

    18" works ok with either rifle or midlength

    14.5" barrel carbine length

    i would never buy a barrel that is over 14.5" with a carbine length gas system.

    Jon, what do you find wrong with 16" carbine gas systems ? That seems to be the general standard on most 16" barrels . I have a 14.5 with a mid system that shoots very soft .

    because its too much gas into the bcg and to offset that you need heavier buffers or buffer springs or smaller gas port. beats the snot out of the parts a little more breakages are more likely of key parts in the bcg.

    your 14.5 the difference between the mid length and carbine length as in how soft yours shoots is that much again with a 16" barrel in a carbine gas layout. its the opposite of what your experiencing.

    if a barrel maker goes out of the way to port a barrel correctly for a 16" and carbine length it will work well. but that is almost never the case. you can alos get around the over gassing with an adjustable gas block.

    carbine length was designed for the 14.5 barrel. lots of barrel makers found it easier to just drill 16" non nfa barrels for the carbine length than puzzle out a new design that works correctly with the 16" barrel which eventually happened with the midlength system

    This is true and spikes is one that I ran into with over gasing a 16" carbine . I believe they do this to make them more reliable with cheap steel , under powered ammo . Its not a bad thing but your right it does over work components . I mitigated the problem with a 4.2 oz buffer which I believe most of their complete rifles come with a H2 buffer to eliminate that issue

    they do it cuz its cheaper.

    the weight of the buffer doesnt offset the gas beating on the bolt carrrier components. the gas goes into the key at higher pressure and slams the carrier open harder which can hurt the bolt lugs extractor and key more than needed.

    the DI system is STILL a piston design but the bolt acts as the piston.

    The Dissy is just a 16" carbine or mid length gas system with the front sight that has no gas function other than to get teh longer sight radius . Its all for looks . If thats what you like get it . Im building a 5.45 dissy / carbine setup right now.

    yes. they arent reliable with lighter loads cheaper ammo etc. can be some issues.

    a dissipator is a 18" barrel with a rifle length gas system. works so-so. its why you dont see a lot of em.

    if you want the look do a 16" mid length with lo-pro gas block and rifle length free float. the vltor casv system looks pretty hot in that config.

    Check out the new EMR rail by ALG (Geissele). It's super light and affordable.
