I have an AR15 SP 1, serial number 213XXX. It is odd to me because I have not seen an SP1 with a delta ring and a newer ejection port cover. Does any one have information on the date of the rifle? Are the newer A2 parts because it is a late production?0429201206a_HDR[19319].jpg

I have not seen a SP1 with Colt A2 parts either. i have 3 SP1 's and none of them have the updated parts. did you buy it second hand ? Seems to me that maybe some one did a barrel change or something and must have installed the A2 parts.. eagle20

I bought it used. The funny thing is 20 + years later I met the original owner at the same pawn shop. He was sorry he sold it, he bought it new and did no changes to it. He only shot 2 mags through it. It would be more work than necessary to change the barrel and also the dust cover. I have been told it is a late model SP 1 toward the end of the SP 1s.

I took a look and found this info .. click on the link it is intersting ..explains why your rifle would have the newer parts ..colt would use up old parts before using new ones ..so they must have run out of the old style ejection port doors and delta rings and put the newer style on the rifle you have.. pretty wild ..

Yeah, but it makes sense. It does have the a pencil barrel and a triangle front handguard cap. I have not found any pics of a rifle with the characteristics of mine. Thanks for the link though.
