| So I been debating on building or buying an Ar. Finally decided to build one after I got a good deal on the strip lower I wanted. My next purchase will be the lower parts kit, I don't know too much about the difference in the brands. I would like some suggestions on brands and why that brand or kit. It would be much appreciated. |
| Most LPKs are all the same. They're just sold in bags with whatever brand you bought on them but they all come from a couple of companies who actually make those parts. There are a few exceptions, but those are usually kits that include JP springs, a CMC or Geissele trigger, KNS pins, or stuff like that. There are also a few places that offer mil-spec kits that have been NiB coated or Cerakoted. Probably buy the cheapest reputable kit you can find. Palmetto State, DPMS, whatever. |
| of note, there has been some chinese made LPK's flowing into the country as well as parts made to questionable specs. If I were you, and I also plan on doing this with my next build(s) is to get an LPK with out the FCG, then go and get an ALG Defense ACT or QMS trigger group. If you want, Weapon Outfitters does custom LPK's with top shelf parts (no chinese crap there). You do pay a little more, but you can get exactly what you want with it. |
| Yeah I definitely don't want any cheap parts, I'm gonna check out weapons outfitters. Also I am thinking of making it a 300 blackout rifle but a lot of the uppers I found I don't recognize the brands. Do you guys know where I can find a good one preferably with a quad rail. |

get an LPK with out the FCG, then go and get an ALG Defense ACT or QMS trigger group. +1 That That's a great idea, especially if you plan on doing something other than standard mil-spec with your trigger. If you're looking to buy a complete upper in .300 Blk, most of the big names are offering them now. Most companies offer them with rail systems, many have multiple options or even let you configure your own. AAC (Advanced Armament Co.) offer complete uppers, as well as DPMS, CMMG, Noveske, BCM, Daniel Defense, Palmetto State, are all reputable companies and pretty well cover the range of prices. There are many more, equally reputable, I just don't have time / space / memory to list them all. If you're wondering about a specific company, post your question(s) and I'm sure you'll get some help. Or, you can always build your own. Building an upper is actually a lot less work than building a lower. All you need is the parts, an upper receiver vise block and vise to hold it, barrel nut wrench (may be included with your rail, especially if proprietary), and a torque wrench (yes, you definitely need one). It's often costs less to buy a "ready" upper, with ejection port door and forward assist installed, than to buy one "stripped" and the parts separately - so you don't even have to worry about installing those items. That leaves just installing the barrel, timing and torquing the barrel nut to 30 - 80 ft./lbs., installing the gas block and gas tube, mounting your rail / handguard, and timing and torquing your flash hider / muzzle brake to 15 - 20 ft./lbs. Not much more difficult than changing the blades on your lawnmower. Plus, there are tons of videos on YouTube to show you how, step-by-step. |

Both of my lower kits came from PSA. Both GTG As above, most of the cheap kits are really only coming from a few vendors regardless of name on box. I also really like psa. That said, the cheap lpks are somewhat a roll of the dice. Ive had a few that are fine and ended up with a couple that are squishy, gritty, not really good. So there is no guarantee one will be as good as the other. But at the price, cant complain. Id vote to give the classic psa kit a go, not the ptac one. |
