So newer ones dont require machining. What do I look at on the receiver with regards to the serial number to know if it will need machining.
Czech Small Arms Sa vz.58 rifles (5.56x45mm)
--------------------------------------------------------------------------------
There is a small quantity of Czech Small Arms (CSA) Sa vz.58 rifle models (5.56x45mm) that will not allow fit and function of the AR-15 magazine well adapter (mag well adapter). Rifles with the following serial numbers will require magazine well modification for the mag well adapter:
5600004CA through 5600127CA
5600008C through 5600089C
If the rifle owner (non-dealer) would like the rifle modified to function with the AR-15 mag well adapter, CSA will provide modification of the magazine well. In addition to CSA covering the cost of the machining, the rifle owner will also receive a 2nd Generation mag well adapter at no additional cost. This 2nd generation mag well adapter has the waffle-type pattern and flared opening to assist with magazine insertion. CSA will cover the cost of the machining, and the 2nd generation mag well adapter (including labor for installation of mag well parts), while the owner will be responsible for all shipping charges. The rifle will be returned to the owner with the 2nd generation mag well adapter parts installed (magazine catch, bolt catch, and bolt catch spring will be returned to the owner as these original parts are not used with the adapter).
If an owner already possesses the 1st generation mag well adapter, and has a rifle with a serial number found in the sequence above, the 2nd generation mag well adapter will be provided as a free upgrade. In addition to shipping the rifle for modification, please include the complete mag well adapter (65), mag well adapter catch (651), mag well adapter bolt catch (652), and mag well adapter bolt catch spring (653). These parts will be used with the 2nd generation mag well adapter and will be installed on the rifle. The first generation mag well adapter will be returned to the owner.

Dan Brown’s e-mail is: dan.brown@csa.co.cz Dan Brown will respond to your e-mail within one business day.
* CSA’s offer of modifying the magazine well expires May 31, 2012.
