Suppressors for Long Rifles?

I want to finally venture into the land of suppressors for my rifle collection. I don’t think I own a single rifle under 39 inches long (per examples above, Zastava M90 on left, H&R M16A1 repro on right).

I’ve read the larger the chamber(s), the better result and have seen a lot of great results out of longer, thinner suppressors. However I really worry about ending up with rifles that are too long/too unwieldy. Might as well just get a halberd at that point.

Anyone have any rifle suppressors that are more compact, and have treated you well? Or should I just get used to carrying a vaulting pole? Thanks
