A few months ago I was in reach of e nearly unused m1a with a 41xxx SN, a co-worker wanted to sell ist. Unfortunately, he couldnt decide to walk the final step and gave excuses for not
giving it away for about six months now...well, I understand him. See thread http://m14forum.com/reference/193540-m1a-offered-good-buy-few-questions.html
Last week I found another candidate (not in a condition als good as the first one, but still "golden Era" range (SN 45317) and for a price of 900 EUR for the set shown on the pic, multitool and cleaning rods already stowed in the rifle stock. Picked it up after two days of communication with the seller.
Didn´t shoot it yet, but with the built-in parts (Barrel H-R dated 1-61, Bolt HRT, Trigger Group TRW, NM Sights) I think I couldn´t do wrong with this purchase. OpRod is not USGI but SA, I guess. No Manufacturer stamp, numbers punched in read first line: 726706, second line 66118.
Now I gotta find the perfect load for my baby...will try N140 with Hornady 168BTHP first.
Edit: After a little search I found the manufacturer code 66118 standing for Winchester...so, my OpRod is probably NOT commercial.
