I put together my first lower tonight. Took me a little longer than I thought, about a hour. Anderson lower and parts kit. UTG stock kit. I got about 140 in all of it. I picked up a PSA upper for 199 shipped, the stainless one, and one of their bolts for about 79 bucks.

My question is this. Compared to my SW MP15 Magpul AR, the parts kit seems a little rough. Naturally right? Any one use one they found was better quality without breaking the bank?

I have 2 more stripped Anderson lowers with parts kits to assemble. THinking I need a 7.62x39 next. Or a 300 BLK and suppress it and shoot deer with it. 

And this one I just put together is my kicking around the hunting club riding a 4 wheeler gun. Or truck gun. No point in roughing up my nice MP.

When u say feels a little rough, are u talking trigger?   If so look at an ALG ACT trigger. Then just buy one of the parts kits that has everything minus thr trigger.

Not just trigger but safety is rougher feeling and parts aren't as solid as my mp15. Just don't sound as solid.

Safety selector looks less robust. Make sense?

Sometimes on a safety is you take a file to the tip of the little detent pin and just barely take the point off they work a lot smoother. 

But I am sure there are multiple quality levels of kits.

A rough safety will sometimes get a little smoother over time. You can also improve the feel of the safety by using a higher quality detent and spring. We use KNS brand springs and detents in our SS-AR's. They lock into position well and have a smoother travel between positions.

When you say, "Just don't sound as solid." Do you mean, the safety doesn't lock in the safe and fire positions as solid as your M&P? If so, make sure you didn't accidentally put a takedown/pivot pin spring in place of the safety spring. That could cause a "mushy" feeling safety selector.

Think in terms of holding a Taurus revolver and then a Smith or colt. It may be the parts kit I have just isn't machined as finely. I think the actual safety switch is less robust looking than my mp15.

For its purpose which is knocking around on my ATV at the hunting g club it's fine. But my mp15 is slicker.

Anderson is a decent lower and their kits are the budget norm. These kits are punched and turned out by the lb. and are purposed for low budget builds. For what you purpose this build for you are spot on. It will probably function very reliably but it would take a fair amount of elbow-TLC to get it just close to mid and high budget builds. The Anderson lower can be built to a very smooth accurate component with top end parts. It's all in what you want to spend.

Good luck with it.

Welcome to the OT!

Not sure your budget, I just did a build that included a lower parts kit from WC and have had no issues with functionality, etc. Nothing really fancy about the lower parts kit other than they claim they to use it on their builds. Note, it does not include trigger, I bought that separate by design.

A smooth trigger makes a world of difference in an AR too me. Makes an AR-15....almost bearable. Big Grin

I saw some video on the internet that said as long as the lower was made out of 7075 or something like that, it was good, no matter how much you want to pay.  So I don't feel bad about my Anderson lowers.

I may look for a more high end parts kit for the next build. Fat boy tactical has a trigger that isn't as pricey as the others out there, I think for around 100 bucks or so. That is where I got the other two parts kits and stock kit to build my other two lowers. 

I really want to do a 7.62x39 one, but I hear good and bad about them having feeding issues. PSA seems to get good reviews on their upper. I will know more after I shoot this one and see how it does. 

I like to tinker, so I may take a stone or some 2000 grit sand paper to the next one. I put some MPro 7 oil on it, and it seems to have smoothed out some. Trigger still not fantastic, but I can solve that issue. 

Thinking I may sell my MP15 and use the $ to build out my last two. I just didn't see the point in dragging a 1200 dollar AR around the woods getting it all nasty on my ATV.  I got 438 dollars in the one I just put together.  

One of these days I will build one completely from scratch. I really enjoyed building this one, I need to tackle building an upper next.

Check out del-ton. They make great stuff and have great prices. I have a delton setup i built that has over 15,000 rounds. Just keeps on trucking along.

For lower kits i have often used cmt or del-ton. Both have worked great for me.

Look into a 300 blk. With the 125ish grain loads they are very similar to the 7.62x39. All u need is a barrel change. Everything else is the same.

Be careful taking a stone to the trigger and stuff. The heat treat is super thin, u take that off and your parts will get soft and can cause malfunction. I was at a carbine class where a guys rifle started shooting bursts. Turned out he did his own trigger job with a stone. School armorer looked it over and said he stoned the heat treat right off and then the edge of a part rounded off so it was bursting.

Those ACT ALG triggers i listed earlier, are amazing for $70. You wont find a better trigger for the price. I have 5 of them and like them alot.

One note about $400 ARs. They often won't be reliable or very accurate. So i would't dispose of your nice one for a couple more cheapos. In my experience reliable ars start in the 700 range. Super Accurate ars start in the 1000 range. Then u can dump a but load more into them with all the fancy add ons we all like.

I am going to shoot it and see how it does. It is the PSA Stainless upper, it has a fairly thick barrel. More so than my MP. My MP might be 5R, I can't remember. It's really a nice gun. It's the Magpul edition. I got it for cost, I had gone in to buy a sport, and they gave me the Magpul by mistake. So i called the shop owner the next day and told him. I couldn't figure out when I got home and opened the box what was up. When I went back down there and saw we'd have to go back through a call to the FBI I just asked him what the difference was. He said since I was honest, he'd let me have it for his cost to the store and showed me the invoice. So I paid the difference. 

My GF got a Sport last year on Black Friday. It's a nice gun too, for the money. I got her a Bravo Co Extended charging handle (she has shoulder problems from a bad wreck) and a Sparc II, and it's pretty sweet now. Oh and a magpul MS1 sling. She got a hard case and mag loader with it and really liked mine, so... she had to have one. Then her dad got one too. I should get commissions.

I hear ya on the trigger, that I hadn't considered, so I will look at another option, perhaps the one you suggested. I am far less intimidated by taking one apart now. I don't like the standard profile barrels though. You know where they have that spot where they get narrower before the end of the barrel. I just don't like how that looks. 

The 300 BLK is on my short list too. I like the idea of suppressing it and shooting subsonic. Then I could site behind my GF's house in her neighborhood and hunt.

That little notch is so you can hook on a grenade launcher.  Bucky  Everyone needs one of those. 

300 blks suppressed are way fun.  I have a 300 in AR and bolt gun.  The bolt gun is crazy quiet.

Welcome to the OT, Lockjaw.
Del-ton and Doublestar are good low cost parts. Personally, I like Stag for my builds. They are more in the mid range in cost.

I doubt I could afford a grenade launcher, much less the actual grenades. It just seems to me it would be a structural weak spot in the barrel. Especially if you were shooting a lot of rounds rapidly. I am sure the army tested all that, so my concern is probably baseless.

I have a few M4 type barrels, I have one that has over 10,000 rounds and it has been just fine.  So I woudln't worry about it to much. 

But on that note, if you want a good barrel SWFA sells Seekins precision barrels which are hand lapped rock creek barrels for under $250.  There is no better deal on barrels available.  They are top notch.  I just got an 18" one today, can't wait to get it mounted up and shoot it.  Got a SWFA SS 3-9x to go with it.

Well my next challenge may be to build an upper myself too. I was very intimidated about doing the lower, I watch videos and even called a couple of the local gun stores with gunsmiths and asked if I could pay one of them to walk me through the process. Both said no, but one was much more helpful and encouraged me to just take a shot at it, and if I got hung, to come by the store and ask for him and he'd help me thru it. 

I got a set of the Nikon scope mounts and mounted an old Simmons 1.5-5 whitetail classic on it and got it bore sited yesterday, so I am pretty excited about getting to shoot it. I got a Magpul MBUS off ebay for less than 20 bucks shipped, brand new, and it was gen 2 model, but it won't fit under the scope and I don't want to take it off just to add the site. 

It's a little heavier than my MP15 MOE, but it has the PSA stainless barrel, its larger in diameter. 

I definitely want to do a trigger in this one and see if it helps. It's not bad, just has creep. It's not gritty like I have see some of the other things say when looking at milspec triggers. 

I really love to tinker.

Uppers are easy as long as you have the right tools. The main thing is having the equipment to hold the upper securely while installing the barrel nut and muzzle brake. The biggest mistake you can make is trying to install or remove a barrel nut by holding the lower and turning the nut. I have seen a few billet uppers broken this way. I don't even like using the vise blocks anymore. I use the Geissele Reaction Rod and Magpul Armorer's Wrench.  

http://swfa.com/Geissele-AR15M4-Reaction-Rod-P92834.aspx 

http://swfa.com/Magpul-Armorers-Wrench-P78811.aspx 

Both tools are a little more expensive than most other methods but it sure beats breaking something. I tried removing the flash hider off of a Daniel Defense using the vise block and ended up turning the barrel in the upper... Daniel Defense won't sell just a stripped upper either. $1,200 mistake after buying a whole new complete upper...All over a flash hider!

Watch the videos on brownells website in building ars. They go through everything.

Magpul makes airsoft back up sights too. So if u paid $20 those are the ones u got. My buddy did the same thing and there is a substantion quality difference.

Package says sight is for ar15. It's an MOE sight. Only way it could be air soft is if it's prepackaged.

The company that makes and sells them are licensed by Magpul.  They come in magpul packaging and have the magpul logo on them. 

Legit ones typically go for $45 to $55.  The fact that you got one for under $20 screams the airsoft version or an actual fake.  Magpul has lots of knock off stuff coming out of china.
