SPR IDF Recce SDM What else am I missing? I have a general idea on the differences between these different configurations. Does anyone have some specifics? SPR 18" barrel seems to be the defining characteristic. Anything else "make" an SPR IDF seems to be a basic AR w/ carry handle and 2 point sling Not sure what makes a Recce or SDM different from an SPR (other than barrel length maybe?) Other configs to throw into the mix? |

SPR = 18" barrel, PRI float tube, ARMS swan sleeve, Leupold Mark 4, OPS INC brake/can, Harris S-L bipod, KAC 2-stage, Matech BUIS SDM-R = 20" Douglas barrel, DD 12.0, ACOG, Harris S-L Bipod, KAC 2-stage SAM-R = 20" Compas Lake/Krieger barrel, Leupold Mark 4 3-9x, KAC 600m, KAC silencer, KAC flip up front sight, KAC free float RAS, KAC 2-stage Recce = 16" midlength, free float rail, S&B short dot or ACOG that's pretty much the gist of it... there is some info in the tacked threads here you might want to read... and wikipedia has entries for most of them too... which based on the technical contact was probably made by someone on here... |
And I thought the SPR was an upper designed to clip onto a stock A2 lower, hence no KAC 2 stage... |
