does the lower and trigger assemb etc need clean? i know the trigger assemb has to oil it, but once thats done, does it ever need to clean it? YMMV, but it doesn't hurt to clean as needed. I at least wipe the mag well and any obvious spots. I don't go so far to take the trigger out though. |

I at least wipe the mag well and any obvious spots. I don't go so far to take the trigger out though. I hardly ever do more than just wipe the tops of everything off. Even with high round counts and/or suppressors getting things dirty it never gets too bad down there. |

Yes. How frequently depends on what you're shooting.
22 and 9mm and other blowback uppers will make your lower filthy with soot and powder residue in a single outing, and it'll require cleaning every time. Clean centerfire ammo through gas operated uppers will not foul as quickly, but it will still get dirty down in there. After your first range trip or two, field strip your lower and see if the amount of dirt on your hands tells you if you should be cleaning it regularly or not. |

Even good ammo will deposit tiny bits of burned powder, slivers of brass from the cases and even a possible blown out primer.
All this can accumulate and eventually can get into critical areas of the trigger assembly and cause a jam. A number of Match AR shooters apply a thick coat of stiff grease to the sides and bottom of the trigger group well specifically to catch and hold blown primers and debris. You should at least use the double ended GI brush to scrub the well as good as you can, and you should apply a little grease to the disconnecter and hammer "hooks" and the trigger and hammer sear area. Every year or so, depending on how much you shoot and how dirty your ammo is, you may need to disassemble the trigger group and give the lower and the trigger group parts a good cleaning. Disassembly is not hard, but you don't want to do it more then needed to prevent wearing the lower pin holes. |
| The most I ever do is blast it with brakleen and follow that up with compressed air (and safety glasses because brakleen in the eyes isn't fun), then re-oil as needed, but I hardly ever do that. Maybe once a year, or if my rifle gets submerged in the river or something. My rifles get used hard. |
