Well, I posted this previously but pulled the post due to concerns about whether it should be public or not. After talking with JBW#3 I am reassured that its not too secret squirrel for public viewing (actually he said I should post some pics).
I reccently traded into a USO 5-25. When it got here I noticed something peculiar-the Erek has a knurled lock ring, as does the windage turret. When I noticed these, I posted pics, because I've never seen these before (and I've seen a USO or two).
Shortly after posting the pics, Doc76251 let me know that what I had in my possesion was a prototype scope built for submission for the SOCOM PSR (Precsison Sniper Rifle) that is currently being solicited. At the time I was advised I may want to keep it on the down-low.
Other than the lock rings on the adjustment turrets, its was pointed out to me that the Erek was an 11 mil setup, intead of the 9mils usually found on USO's. Aditionally, although it is marked and sized as a double turn Erek, it will only complete one revolution. This is another spec that is called for for the USASOC day optic-a single turn turret for the ballistics of M118 and A191 to their effective ranges (hence the 11 mil turn-A191 is spec'd for 10.6 mil to 1100m).
As far as the scopes submitted for this project, doc76251 had this to say:
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: doc76251</div><div class="ubbcode-body">FWIW, USO was the only application to hit all the bench marks for the scope in June which was the deadline. Since no other optical company achieved the designed requirements the tests were pushed off until Sept and further. Read into that what you will.
Cheers,
Doc</div></div>
Anyway, for those interested, here's an excerpt of the requirements for submitted scopes:
<span style="font-style: italic">H92222-09-PSR
Draft Performance Specification
26 Jan 2009
3.2.5.7.1.2 USASOC Scope, Dial In Method. <span style="font-weight: bold">All telescope turret adjustments will be in mils and
tenths of mils </span>(T), (KPP). The USASOC Scope <span style="font-weight: bold">will exhibit tactile clicks on windage and elevation
turrets (</span>T), (KSA). Both windage and elevation <span style="font-weight: bold">turrets will exhibit a performance feature of
“Single Turn Turret”</span> (T), (KSA) – a feature that allows the Operator to achieve the preponderance
of elevation and windage needs within one single turn (10mils), but also allows the Operator to
completely dial in his range needs if desired.
As examples of Single Turn Turret (minimum 10 mil/revolution):
M118LR, 2640fps, BC .505, 800m Max Eff Range = elevation 8.4 mils
A191, 3000fps, BC .533, 1100m Max Eff Range = elevation 10.6 mils
.338, 300gr HPBT, 2800fps, BC .768, 1500m Max Eff Range = elevation 16.7 mils
<span style="font-weight: bold">The USASOC Scope must have Zero Stops on both windage and elevation </span>(T), (KSA). The intent
is that the USASOC Scope allows the Operator to use graduated reticles on a 100m Zero (Zero Stop
at 100m zero) and utilize exclusively mil reticle Hold Off for all ranges, or the Operator may choose
to Dial In the complete range elevation need, or a combination of both. It is critical that the
Operator can easily identify what revolution he is on without going back to Zero Stop and dialing
up (T), (KPP).
3.2.5.7.1.3 USASOC Scope, Hold Off Method. <span style="font-weight: bold">The USASOC Scope shall have a lockable
elevation turret </span>(T), (KSA), allowing Operator confidence when using the Hold Off method that the
zero has not been disturbed since the turret was locked. The USASOC Scope should have ability to
zero and Zero Lock without tools (OPA). The USASOC Scope will have a streamlined Windage
Turret (Zero use only, normally capped) (OPA). The USASOC Scope will have a mil-graduated
grid reticle that facilitates immediate lead and range Hold Off for rapid target engagement (T),
(KPP), the Horus H37© being one commercial example. The USASOC Scope will not contain
proprietary reticle patterns that would inhibit open architecture (O), or there will, at minimum, be
contractual terms for the government, through licensing agreement or other consideration, to
acquire any proprietary reticle patterns and achieve open architecture (T), (G-NG).
3.2.5.7.1.4 USASOC Scope, MRS. The USASOC Scope shall have a means to utilize the
SOPMOD MRS (O) or other means of urgent, close-range, day/night self defensive aiming (T),
(KPP).
3.2.5.7.1.5 USASOC Scope, Parallax Adjustment. <span style="font-weight: bold">Manual parallax adjustments, if any, will be
collocated with the windage and elevation turrets </span>(OPA).
3.2.5.7.1.6 USASOC Scope, Power and Reticle Rleation to Power. The USASOC Scope should be
of variable power (T), (KPP). <span style="font-weight: bold">The lower power setting should be, 5 power (-1x, +3x) power (T) or
less (O) on lowest power. The highest power setting should be and 25 power (-1x or +1x) (T) or
greater (O) on highest power. The USASOC Scope must have its reticle in the first focal plane (T),
(KPP)</span>.</span>
