I'm planning a Tantal (Kbk wz. 1988) build and want to confirm some of my information before I proceed. Much of the rifle is reported as garden variety AK74, but a few parts (buttstock and FSB) are visibly different.
I obtained a gas block, front sight base and trunnion from Apex, but could not find a Tantal rear sight base for a reasonable price. I have a spare AK74 RSB. Could an AK74 RSB be used instead?
Unlike the AK74, where the FSB is not threaded for a muzzle device the Tantal barrel threading is 14x1 LH, like a standard AKM. Still looking for a Tantal style brake to fit. I have a spare AK74 bolt group, I assume this is interchangeable based on what I've read, but would like that verified. AK-Builder sells the flats, already bought the rivets on Apex order. Now there is just a barrel.
I'm leaning towards using an intermediate or NATO length AK74 synthetic fixed stock. The (expensive) folding wire stock (basically a copy of the MPi-KMS-72) is a bit short for my tastes and I'd have to pin it open anyway. If I can get one for less than $60 I might add an elevated cheek piece on a wire riser welded on and add a spacer to the stock trunnion to add length, which is another option.
Curtis was out of stock on the Tantal barrels and said it would be "awhile" before they produced more. The only reliable source of barrels (and fairly well regarded from what I've read) is from here:
High Standard (Houston TX), Tantal barrels are chrome lined, in the white, all journals based on a barrel from OBR (Osrodek Badawczo-Rozwojowy). 14x1 LH threading of the muzzle, gas port already drilled, notched for handguards, extractor relief groove cut. Price is $139.50 + S&H. Order # 1-800-272-7816.
and here:
Green Mountain Barrel (Conway, NH). Can be ordered from their website for $145 + S&H. http://www.gmriflebarrel.com/search?searchvalue=Tantal.
