Anyone have experience with one?

Anyone have experience with one?

 

Yes. I have a Sig SCM 556. It has been trouble free for about 2K rounds.

I also have the Sig SCM 556.

Things I like: Once I started using pmags I have not experienced a ftf or fte.

It has so far provided consistant 2" groupings at 100 yards.

Easy to field strip.

Ambi fire controls.

Nice feeling stock grip.

Imho it is neat looking.

 

 

Things I don't particualrily enjoy:

The stock magazine I received was terrible. It has also been finicky with other cut down ar mags.

It is a bit front heavy.

Stock forearm on the SCM at the time I bought it felt awkward.

When I purchased it the rear buis was a flimsy little piece of metal. Purchased the rear diopter and that has worked pretty well.

The version I bought did not come with muzzle break. As a result it is extremely loud. Good for a giggle factor. Not bad outside, but indoors doubling up on ear protection is a must.

Cost 25% more than the Bushmaster I bought after this.

 

I still shoot it occasionally, but for the classes I've taken I've used the AR because it is lighter, easier to perform side to side transitions, and the stock irons are good.
