GreyGoose Posted September 24, 2015 Report Share Posted September 24, 2015 (edited) Gents,As we are all aware an "SPR" is chambered in 5.56. (Mk 262 OTM/77gr SMK's/Noslers)There are various other specifications to consider however if you wouldn't mind I would like to hear what your principle definitions of an SPR are aside from caliber.I am/was under the impression that the term SPR had become ubiquitous, almost like the word kleenex, in that it represented in general terms a precision gas rifle with a flat top receiver, BUIS, a optic, bi-pod, fixed stock, 18"+ threaded barrel, MB or suppressor, etc.I know it is used in that regard in my AO, not in a technically historical definition, but rather in a general platform application sense, perhaps wrongly so.What say you?Thanks in advance for the feedback!-GG Edited September 24, 2015 by GreyGoose Link to comment Share on other sites More sharing options...
98Z5V Posted September 24, 2015 Report Share Posted September 24, 2015 Easy - answered you in the other thread you tried to take over.SPR - first, "Special Purpose Receiver." Later, it wasn't just an upper, it was a whole "Special Purpose Rifle."Way off the mark, for yours.Read and learn.https://en.wikipedia.org/wiki/Mk_12_Special_Purpose_Riflehttp://www.precisionreflex.com/Content.aspx?PAGE=Mark12+Mod+0+SPRhttp://www.ar15.com/forums/t_3_118/520524_Official_Mk12_Mod0__Mod1__ModH_Photo_and_Discussion_Thread__Part_II.htmlWhy don't you hop in that thread on ARF, and ask them if you have an SPR?...

98Z5V Posted September 24, 2015 Report Share Posted September 24, 2015 SPR: Mk12. Any variationTHIS... however, is the Mk11. Completely different rifle, but derived from the Mk12.

98Z5V Posted September 24, 2015 Report Share Posted September 24, 2015 Opps, left out the Mk12 Mod 1. The "second gen" - or 3rd or 4th gen, if you know the rifle...Thank you, DogFightInk for the pics - you guys rock. Link to comment Share on other sites More sharing options...
