gas trap bolt

[enfieldman]

Is there a difference between a gas trap bolt & the later gas port bolt?
I picked up a nice garand with five digit serial #, 48,XXX indicating an original
gas trap rifle, but has been converted to gas port. The bolt is an SA-12 and not
the original.
I want to know if during conversion from gas trap to gas port would the bolt &
operating system also have been changed or if not, why would the bolt have been replaced??
Rifle has nice crisp stamps & cartouches & shoots great.
Help please!!
Phil.

I don't think the bolt or op-rod would have had to be replaced during conversion, though they may have. Who knows when or why a Rev. 12 bolt was put on the rifle. Could have been at anytime after about Mar. of 1942. What are the cartouches on the stock ? The rifle may have gone through a rebuild program, post WW2, and have many other parts not from it's original build. Such as the rear sights and internals. Hopefully RCS will see your post and correct me if I am wrong and offer more information.

The reason so many Gas Trap bolts survived is that they are fine in all rifles. Modern bolts work in early receivers, too.

Actually...a picture set would be nice. Nothing like pics to show us what you have there.

Yes, really hard to say without seeing the rifle or good pictures. Considering the SA-63 barrel it was surely rebuilt. I think it was sometime in 1963 that rebuild marks were etched on the right receiver legs. Before this time the rebuild cartouche would be stamped on the stock in the location you described. So maybe it was a early 1963 SA rebuild. What month is the barrel ?? I would be surprised that it would have gotten through a 1963 rebuild and retained a lock bar sight, but who knows ? Sounds like a nice rifle and you have some good parts. Bottom line "it shoots great", enjoy it.

Joe, the barrel is marked SA6535448 7 63 Y28
upper case P M with the later `eagle` acceptance stamp.
Also, came equipped with a W.T.& B.Co.
1918
C.A.C.
leather sling & U.C. with `flaming bomb` stamped bayonet.
I have had this rifle in my collection for about 10 yrs. now, I have 2 others both SA
and both post Korean War ser.#`s. I will take some pics tomorrow and try to post.
thanks again
Phil.

So, it appears the barrel is a very late one. RE barreled in 7 of 63...bayonet is Utica Cutlery but they've been making repros marked U/C...the sling sounds like a WW1...all remains to be seen. If you have difficulties posting pics, PM me and I'll do it for you...

Your 48,xxx rifle would have had a revision 2 bolt which entered the system during the end of gas trap production, The gas trap bolts are without the small bottom hole which came with the revision 2 bolt. The revision 2 bolt lasted into early 1942. There were some different milling patterns on revision 1 bolts but unable to post a photo
