You're right. It should.
I think many dealers here have same or similar product lines. Some specialize in this or that and would therefore standout in those areas of service or product.
But general accessory stuff
Operation Parts: Because he ships stuff immediately and all my orders have shown up in 3 days or less- Nice guy to boot
BravoCompany: same thing. Good outfit, helpful and contributes here intellectually as well as sponsorship wise
DSG: just found them but CS is A+. Actually called to see if I was happy with order ( a small order at that) Unheard of for me, and they can count on future biz
Also like SKD for their promotional efforts and initiative
Magpul: great stuff, good service
CSGunworks: because the sales guy works his ass off to help out (and I know it is in small part because he makes something off a sale but so do all the others and they don't work as hard)
and the list goes on..............
In fact the only "less that expected" service I have seen/heard- wasn't with me. It was heard here on the boards
Pretty impressive for an industry that has had taken its share of lumps over the years.
