    The standard lpks are the same for all calibers except for 9mm IIRC, I'm no expert, but it looks good to me.

    That lower is awesome BTW.

    Well it has upgraded parts like the pistol grip and ALG trigger. If you want those things it may be worth it but you could get an LPK or LBK from PSA or others for less money and upgrade parts later if you want.

    Nice lower by the way!

    Thanks guys! They claim these parts are forged, which I guess makes them stronger than the average LPK? The Grip I will change, but I think I'll keep the trigger, and I love that it comes with a good Ambi-selector switch. it's Badass ;)

    So if i was to keep everything but the grip, would this be a decent deal for the LPK?

    A standard PSA LPK is $60, add the price of a lower and it comes out to $160-$180. So yeah that's not bad, even without the grip.

    Ahh i think you guys are missing the price here. The LPK ALONE is 135 with the special ambi selector and not totally crap but better than normal trigger. Lower is 175 by itself.

    Ohhhh....:eek:

    I looked up the trigger, it's just a standard mil spec trigger with a $2 trigger job done on it.:p

    But the Safety selector runs about $60 so it's not a terrible price I don't think.

    The lower itself is a little too expensive in my opinion, but it's just freaking cool.

    I think ill get the lpk then. The lower is perfect for me. I love the resident evil games. Hell, my avatar is the T-virus. The nerd/firearm enthusiast onme can not pass this up.

    Although it seems all LPKs are the same, they really aren't. I've see too many pictures of broken DPMS bolt catches. Also, my friend broke the tabs off his alloy lower, when he was trying to install a triggerguard with an out of spec DPMS roll pin.

    I'd highly recommend spending $10 extra bucks and getting at least a PSA (who sources their parts from FN's suppliers), Daniel Defense or G&R.

    Thats kind of what i was trying to figure out, what makes some lpks junk and others good. This one they are claiming to be forged, but i couldnt find any info if that was a desired feature or not. It seems like this would be one of the better sets, but iust dont know for sure

    $175 for a stripped lower you love is not extravagant. So it's $50-75 over a plain jane lower, that's a drop in the bucket when you look at the cost of the complete rifle. You'll be glad you got the rollmark you really wanted plus it's the first thing your friends will look at when you say "how do you like my new build". If you don't get what you want, over the years it'll bug you until you finally sell it.

    Usually it isn't specified whether lower parts kits use forged or billet components (besides, the type of steel is more important than how it was shaped). I just checked at BCM and their Stag, RRA and DPMS LPKs don't say. No doubt it depends on the part, a trigger or hammer will be different than roll pins and detents.

    Even BCM's complete lower doesn't specify much about its LPK.

    I'd get a good kit and not worry about it too much. Two LPKs I've used that I didn't like were DPMS and DTI, the Stag, ArmaLite and Daniel Defense were much better. The kit you're looking at sounds good with the upgraded parts (if you like those upgrades). I think you want it so just get it and enjoy building your new lower!

    Dude that's a sweet lower and the LPK includes all the upgrades you'd probably want to the do anyway. Add spikes buffer tube assemly with an ST-T2 buffer and Magpul stock and that will be a really nice lower! I have a build with ALG QMS trigger and it's a nice improvement over most stock triggers.

    http://www.joeboboutfitters.com/Spikes_Tactical_6pos_Milspec_Carbine_Stock_Kit_p/sp-sla500r-k.htm

    It's out of stock now but get on the notification list as they do come back in stock often enough. There's other places around that may have them in stock now.

    You may want to order a spare LPK before you even start the build as they are always good to have around and it's easy to launch the pivot pin detent into oblivion on your first build never to be found. Then you’ll be pissed you can’t finish it till you get more parts, I know this...don't ask how :eek:

    Thanks! I actually had already chosen that exact buffer kit :) and i was going to do a CTR stock. As far as assembly goes, i just need some roll pin punches and a hammer right? Any specific hammer?

    Bolt stops from any maker will break if you snap the hammer against them. NEVER pull the trigger on a bare lower w/o controlling the hammer. It will snap the bolt stop with ease.

    That is my go-to combo. Have it on four builds now with the enhanced buttpad.

    For the hammer get a two sided one with metal/brass on one side and nylon on the the other. Other than that the roll pin punches and you're good to go for the lower.

    Really, really good advice/reminder!!!
