Has anyone even had the opportunity to look thru one of these? Advertised on several sites as either a FFP with the BTR1 reticle, or SFP with what appears to be a fine-line mil dot. Both types illuminated, both scopes on SWFA for what seems to be very reasonable prices...... I know most folks here are looking at much more refined scopes than these, but I would appreciate professional opinions, i.e. Are these the equal or better than TAC30 and/or MTAC? Are they worth a look? Thanks!
