Colt SP-1's For Sale

A friend of mine who works for the Florida State Patrol recently traded some Colt SP-1’s to a large gun/ LE distributor. They are now being listed on Gunbroker. If someone really wants an SP-1 it may be worth looking into.

I bought one of these. Does anyone know the difference between the SP1 and the early AR-15A2 Sporter II ? They look visually identical.

The AR-15A2 was the first A2, had a Gov’t profile barrel in 1/7", with case deflector but A1 rear sights. Should also have the A2 buttstock and A2 forend.

Three left at $700.00. Tempting…
