The M1A is not an M14 in my 300 round experience:
#158,XXX
1. The rifle was delivered new with a broken stock which was replaced by SA.
2. Rifle would not seat fully loaded USGI or SA mags. 19 rounds ok.
3. 97% reliable with about 3% failure to feed.
4. Bolt roller retainer came off during firing and was found in the op rod track while cleaning. Replaced.
5. After 300 rounds, the hammer now follows the bolt forward during recoil. This is not poor trigger control as it is reproduced with an empty rifle. Fortunately it did not fire out of battery or go full auto.
Data:
Ammo is South African and Austrailian surplus only.
Grease is Automotive ball bearing grease to metal - metal surfaces.
Mags= 3xBRW S-1, 1x KMT, 1xOM, 1xUHC, SA 10 rounder
SA has the rifle now and is paying for shipping to and from the factory. They seem to be standing by thier product, but losing $50 shipping costs every time it breaks is not going to help their profits.
