first off, it doesnt count if youre not starting with an SR22 (not the 10/22) the cost is dramatically different.. as is the canadian dollar difference (50% when you account for markup and special ordering KIDD stuff).
i guess if youre ordering custom uppers/lowers maybe, but the SR comes with a good heavybarrel already threaded and a decent receiver that has a great milspec kind of look and feel to it.
SR22 = $749 IF you can ever find one. i got mine for 650 at phoenix indoor range, the last one, no more stock coming, out of the delivery of 5 that they got from placing an order for 25 originally.. theyre in serious short supply)
POWER CUSTOM match bolt
Timney trigger group
Rails
Muzzle brake
Buttstock (Magpul or similar, to taste)
KIDD springs/guide rods (two sets in case of loss/wear since they take 3 or 4 months to source up here in canada usually)
Scope rings (I like vortex TRXHAC some of the best and most expensive available)
titanium extractor, firing pin, etc for replacement parts.
a couple drum mags.( i had to buy four in order to get one that works reliably and one that works semi reliably, two were garbage).
Charging handle (also kidd, work an effing mint)
IDF type angled foregrip and thumbgrip
45 degree mount for offset front reddot
magpul single point sling attachment
Then add a couple optics of your choice, a cheapass millet BMS scope or a decent vortex diamondback at least, and a reasonable reddot will run you $500 to $750 combined even used will be close to that...
Then throw the whole mess into a pelican custom cut foam gunbox for transport, display, and sale. ($225 or so if you get a deal online)
