Not sure why you think the bolt carrier isn't original, pretty sure that's what most SP1s left the factory with.

Kind of hard to tell from the pic, but are you sure it's an A2 and not an A1 flash hider? If it uses a split washer and has a slot at the 6 o'clock then it's an A1 and correct for that rifle.

Buttstock "twang" is perfectly normal.

Does looks like a A1, but he wants the earlier three prong one.

Yeah, I understand that. It just sounds to me like he thinks it should have the three prong when in fact it left the factory with an A1. Almost like he's confusing it with an M16 versus an M16A1, instead of comparing it to other Colt SP1s.

Sorry did know I didn't know about A1 vs A2, they are all birdcage to me)), but i want original "Vietnam look" to it, that's the reason i got the gun )). I got it used, with different bolt. Thou it be lubed and cleaned, it looks like it might have been a truck gun decades back, not beaten but it have been used, came with NCstar sight on top :rolleyes:

Fair enough, but did you know that the army only adopted the M16A1, which came with the A1 birdcage flash hider? The upper had a forward assist as well.

Putting a three prong on there would make it resemble an M16 but that rifle was never adopted by the army, it would be correct for the air force however.

The army did use the M16 and later upgraded to the A1 around 66-67. The 3 prong would be correct for an army gun depending on the time frame.

I'm sorry but that's a common misconception.

The Air Force adopted the M16 in 1962, not the Army. The Army found the M16 to be lacking and wanted a forward assist and birdcage flash hider, these changes resulted in the XM16E1. The XM stands for experimental. The Army started issuing these rifles to units in '65. It was standardized in '67 as the M16A1.

I'm talking about standard issue weaponry, I'm sure that M16s of all kinds were used by specialist units and in small programs all over the place but they were far from standard issue.

In the end I suppose it doesn't matter. It's the OPs rifle and he'll do with it what he wants, I'm just trying to educate him. I made the same mistake myself when I first picked up an M16A1 clone. I put up WTB in the EE for a teardrop forward assist, straight slip ring and three prong flash hider because I thought them correct. I was right about everything except the three prong. Now I could install it anyway because I prefer the looks but that wouldn't make it correct.

The OP has an SP1 slab side upper so it's already more similar to an M16 than an M16A1 so in that case I'd probably throw on a three prong anyway.\

ETA: Was just cruising the retro forum on arfcom and it appears that the three prong is indeed correct for the XM16E1 and did appear on some initial M16A1s. They have fantastic guides on all the variations of rifles and carbines, a great reference.

Yeah it is a good guide. It is what I used to see which parts I needed for my XM177 clone.
