Is there a good place on-line to order parts such as bolts, extractor springs, buffers, firing pins, etc. etc. etc.(basically all the needed replacement parts) to stock up on.

Thanks-MATT

Bushmaster and DPMS both have replacement parts kits (springs, pins, gas rings, firing pins, etc.)
prepackaged in different configurations for sale at their websites.

That reminds me, I need to buy a few spare parts myself. Thanks for the reminder.

No prob, thank you sir.

Just out of convenience/habit I use Brownells, but there may be better pricing/parts avail elsewhere on the net.  I'm skeered of the internet so I usually just order through a buddy's Brownell's account.  Hence, I'm not sure of the retail end of the parts.  Brownells has DMPS as well as other manufacturers' offerings including Magpul, Yellow Tavern, RRA, and specialty companies like JP & Wolff.
