If you are interested in buying an HK-91, you ought to do so soon.  They
have been on the federal import ban list for two years, and are becoming
much more difficult to buy.  I have an HK-91 A2 in excellent condition
with most of the options you specified which I'd like to sell.  Why? 
More outgo than income these days.

First, some general information:
1.  The A2 model does not have the collapsible stock, the A3 does. I have
the stock with adjustable cheekpiece from HK, in addition to the regular
stock for the A2.  The current price for the A3 stock is about $245 to
$275.
2.  Barrels on HK's are not user replaceable.  You'll need to contact and
HK armourer or HK service in Virginia.
3.  rder to use the heavy bipod (which I have), you also need to have the
slimline forearm.  (The heavy bipod and standard forearm conflict.)
4.  Laser sights and HK-91's are a mismatch.  Even the best profes-sional
grade laser sight is useless in daylight (not bright enough to be seen @
5nW output), and is limited at nighttime to 100-300 yards (varying with
the color of the reflecting surface, and divergence of the laser beam.) 
Typical dot size at 100 yards is 4 to 6 inches . . .

Prices on other items you asked for (which I don't have):
HK-91 A3 retractable metal stock is $270.00, HK-91 spare barrels (don't
have a published price that I've seen - contact HK dealer.)

Interstate transfers/sales will need to go through dealers with FFL's at
both ends in order to meet state and federal requirements.
