Lower parts kit question

Post by Dutch253 » Sat Jun 17, 2017 5:34 pm

I've started my first AR build and went with the Aero Precision ambi stripped lower. I got a little confused when I started picking parts for the lower though. When I did the math, the parts cost around $300..for a lower that cost half that! I didn't select anything over the top or exotic. This is my first build so the question is, is this normal?

LPK (lower parts kit) should be in the $30-50 range most places. Unless you're getting the extra special smoothed, shaved, titanium, unicorn blood trigger stuff. Match level trigger assemblies can go for the $300 you're mentioning, so perhaps that's what you're looking at?

But the standard LPK I got from PSA was right around $30 and worked like a charm.

Hey Dutch, I would check out PSA. A parts kit itself should only cost 20-40$ for a very basic kit. you can of course get much more expensive sets that have a lighter trigger pull weight. I would link you some however I'm at work and don't like to search gun parts at work.

But PSA has some, Midway USA has some, I believe you can even get some off Amazon. The only kits that should cost that much are VERY high end light trigger pull kits.

Good Luck!

So the kits I was looking at included more than just the springs and pins. They had the grip, trigger, take down pins, ambi safety selector and the trigger guard.

Just LPK or buffer, tube, stock and the other parts required to finish a stripped lower? Most people just all the trigger and springs the LPK.

Some if the parts you will choose depend on what type of complete AR you are looking to complete. Do you want a carbine length rifle? Or will you want a longer barrel to complete a full rifle length AR?

Below are the basic parts to complete your lower for a carbine. Brownells is having a sale this weekend and has DPMS complete lower parts kits for $39.95 and a complete carbine stock kit for $49.95. Basically for $90 you would have a complete lower half. If you use coupon code M6S you would also get free shipping.

Complete lower parts kit

Complete Carbine Stock Kit
http://www.brownells.com/rifle-parts/st ... 44659.aspx

If you want a complete upper for your AR, you would also receive a free $25 gift card with the purchase of this upper.
http://www.brownells.com/rifle-parts/re ... 86806.aspx

The final part you would need is either an optic or basic "iron" sights. I would suggest these sight if you just want something quick, easy and inexpensive.

One other thought. Keep in mind you will need a small hammer and a punch set to complete the lower. If you don't have one or don't know anyone that you can borrow them from you can use the ones in the following links:

8 oz. Ball Pein Hammer
https://www.harborfreight.com/8-oz-stub ... 95930.html

Punch Set
https://www.harborfreight.com/5-piece-l ... 93111.html

Are these the best tools money can buy, no. But to get the job done for one lower receiver they are perfectly fine. However, I would suggest investing in the following tool for placing the bolt catch release pin. It will help you keep from marring the side of your receiver while pushing in the bolt release pin. If you don’t use this tool you can cover the receiver with vinyl electrical tape to protect the finish. Don’t be shy with the tape!

Sorry, thought keep rolling in.

If you haven’t actually already purchased your AR lower here is a link to a complete kit with every part you need to build a complete AR15 all in one box.

http://www.brownells.com/rifle-parts/re ... 88054.aspx

Personally I’d use an 80% lower receiver but that requires additional tools that you might not have access to or be willing to purchase.

Enjoy.

I'll take all that into consideration, thanks.

I pretty much stick to SOLGW LPKs with thier "fighting trigger" wich is basically thier version of an ALG ACT trigger. Thier parts are none mim and on par with BCM and DD, the lpk+trigger are around $80. Sionics Weapons systems also sells complete blemished lowers for $200-250 with a NPQ or Nickle boron coated trigger,QD end plate,magpul grip,good buffer springs. Both Sionics and SOLGW are "combat grade" hard use type stuff and not lifestyle brand crap. I'm a noob here so feel free to ignore me or interrogate me as needed.

I'd say it's more of a PG-13 type that leans towards R rated on occasion.

You can curse, but keep in mind that folks often browse ZS at work or around their kids.

We don't get many zombies here, but we do get the occasional troll who comes in, makes a few idiotic posts and then gets banned by whatever moderator on duty that day.

If you want to laugh or feel your IQ drop, I suggest looking up posts by 'Zantra', 'Longy' and 'Hokicake'.

We're all still unsure if those were three different people or just one really determined person with multiple accounts. :lol:

I knew I forgot something. Thanks, Woodsghost.

Back on topic, I've been seeing the DPMS and XTS branded lower parts kits the local Academy store and I'm considering picking one up for my eventual AR build.

I know DPMS' quality is decent enough for a plinker, but I've never heard of XTS. Anyone use the XTS lower parts kits ? If so, what's the quality like ?

Well, first you’re gonna need a Ciener .22 conversion...

:lol:

I’d just grab a PSA lower parts kit with some flavor of the ALG trigger when they go on sale. Many versions... You can get just the LPK and piecemeal the rest when they’re on sale too. Sign up for the deal blast email...can get annoying with multiple emails every day, but lots of good deals pop up.

Currently out of stock, but here it is with a Magpul MOE stock and grip: http://palmettostatearmory.com/palmetto ... igger.html

I’d get the 7075 series aluminum mil-spec buffer tube vs. the 6061 “mil-spec size” tube for a few bucks more, though either will do just fine. I have builds with both and no issues.

Have you built the upper yet?

PSA also has the magpul MBUS set on sale for under $100.

Re: parts, I spend money where it matters: bolt/bolt carrier, trigger and barrel. Unless it’s a specialty build with lightweight parts I almost always use Bravo Company/BCM or Daniel Defense (DD).

Almost every rifle I’ve built has a BCM bolt (most with a BCM carrier too) regardless of cost...simply the best in my experience.

Every one of my personal rifles has a Geissele trigger, again the best trigger for my needs...ALG gets you 90% (or more) of that trigger for 1/4 the price. Built on the same EDM wire cutting machines as the Geissele triggers, just not guaranteed to be match grade. I have ALG triggers in most of the builds I’ve done for friends and family.

Barrels are a preference thing...a lot depends on what you need it for. Hard to go wrong with any flavor of BCM or DD barrel.
