Early sp1 suppressor

[keith smart]

Just scored a 4 digit ar15 and will pick it up at NGD this weekend. The original owner swapped out the 3 prong for a birdcage, perhaps aniticipating jungle warfare.
Anyway, how hard will it be to locate an original Colt's suppressor?
Thanks in advance,
Keith

There's a guy in this neck of the woods that has dozens of them at every gun show.

early three prong on a Colt SP1 Sporter in the three digit serial number range, note the "thin" barrel and flat front sight base too

[Ltdave]

should that have tapered 3-prong or a duck-bill 3 prong?

the FIRST were straight (considerably smaller O.D. than the 'base' of the suppressor) with radiused 'step down'....

they were way to easily bent or broken off...

3-prong


duckbill


if its early enough should it have one of these? Delta shaped charging handle?

This Colt SP1 with a three digit serial number came with the three prong hider and black plastic - it is like new and not put together - it came that way from the factory. The Colt SP1 Sporter manual also has photos of serial number 100 with this same three prong hider too.

Maybe both types were used - I do not have any idea

[Ltdave]

the duckbill must have been on the earlier mil-spec (contract) rifles...

thanks for the correction...

The best thing about the old open three prong was its usefullness in opening cases of c-rats. Of course you would get an article 15 if the wrong person (first sgt or officer) caught you doing it.

Opened many a case of rats with the flash hider. Had to be sure you twisted clockwise or you loosened the hider.
