Converted my A2 "Postban" to an A3 "Noban." Have the following pieces for sale:
16" Post ban (no evil features) 1:9 heavy barrel. No muzzle device. Excellent condition. Less than 200 rounds through it. Complete with FS tower, FS post, stock sling swivel, etc. $135 + $8 shipping.
Looks like this, except mine has the forward sling swivel.
Paypal or certified funds only.
