Vortex DOES offer a 2.5-10x 32mm FFP Mil/mil or Moa/moa scope now. |

FMJBT made me aware of that a little while back. I made that comment when Vortex didn’t have that option available. I did talk to Vortex over a year ago about making a revised 2.5-10 like this; I wonder if it was my voice that was actually heard. I’m still considering a Bushnell 3-12 FFP with the G2DMR reticle instead… I have a few pieces of Vortex glass already and feel like trying something new. Thanks for the heads up tho. |

I have it sitting on a dedicated target rifle and I’m always at max mag. The SFP crosshair thickness is more pleasing to use when shooting groups. |

Got bored and decided to camo mine:
Also built a muzzle shroud for it to attempt to reduce the amount of dust kicked up from the Ops Inc brake. It does kick up a little less dust now, but is still extremely loud due to the large side ports. The extra weight up front, along with having the last few inches of barrel under tension from the mount have helped with accuracy somewhat as well.

Just got the scope this past weekend while I was out in Vegas. I'll feed her some 65gr and 77gr ammo once I get the projectiles.
Btw, that SPR you got there is champion she is. I'm really digging your freefloat rail. And that anno job is very nicely done! How's she shoot -- what type of ammo are you using? |

Agree...that rifle is looking very nice, indeed! Btw, his shroud you're referring to....you mean that thing that goes up?

I'm running the Bergar SPR barrel sold by PRI on mine. It's the "budget" option to the Douglas barrel they also sell. Accuracy out of this rifle has been really good. Fist time out and it was shooting around 1 moa. After a few trips to the range and several hundred rounds of mechanical break-in it would shoot into 3/4 to 1/2 moa pretty consistently. Since the addition of the "shoulder thing that goes up", more often than not it ends up being 1/2 moa. Due to the ammo shortage I have been shooting reloads almost exclusively through this. My favorite load so far is the Nosler 77 grain BTHP over 24 grains of Hodgedon CFE-223 loaded to 2.25" in Lake City brass. Running the numbers I've been getting for drop at 650 yards (5 mils), this round is getting about 2820 FPS out of the muzzle.

It's constructed of various 300 series stainless fittings that I found at McMaster Carr. The external tube is 1.5" seemless tubing. The mounting end is a 3/4" Sch. 10 Stub End, bored out slightly to clear the threads on the Ops Brake. Welded to the end of that is a short section of 3/4" Sch. 40 pipe nipple that has been internally threaded to 22X1 metric thread. The stub end was then tig welded to the end of the 1.5" tube. The external tube is ported in multiple locations in the area covering the muzzle brake, 6 ports in all. Internals ahead of the muzzle brake consist of a "Spool Piece" made from a section of 1/2" stainless tube with a washer welded on either end. The spool piece serves to reduce the internal volume of the shroud, giving even less room inside for any expanding gasses. The internal stainless tube is not drilled or ported in any way that would allow gas to be stripped away from behind the bullet, and the diametrical clearance between the bullet and tube is large enough to allow a large volume of gas to exit with the bullet. The washer on the inside is plug welded through the external tube in 8 locations around the perimeter, and the one on the outside end is fully welded for an extremely permanent installation. The smaller ports along side the shroud are there to allow insepction of the internals to verify that there are no internal baffles of any kind, and also to allow any gas that may end up bypassing the internal end of the spool piece to exit without "slowing and cooling". The assembly threads on just as the original can would, indexing against the tapered collar for a 2 point mount. This required a small bevel on the inside of the 3/4" stub end to sit against the collar. I made a very slight bevel by spinning a 1" ball bearing against the opening with a lot of valve lapping compound. By controlling the depth of the bevel, I was able to time the shroud so that it threads on and seats at the same point everytime it's installed. Did a quick diagram in paint that should help explain a bit better:

May not be all that flashy for those tactical types but the sleeper gets the job done, and yes these were at 300 yards.

Posted this rifle before. LaRue, LaRue, LaRue, Shilen, yadda-yadda. No longer for sale.
Dropped a Vortex PST 2.5-10x32 mil/mil FFP on there. Talk about bang for the buck, what a great scope. |

My latest project in the pursuit of lightweight precision: A 14.5" with pinned/welded Ops Inc chambered in 300 Blackout. This probably belongs more in the "RECCE/Recon" rifle thread, but due to how heavily it borrows from the MK 12 Mod 0, it's getting added here.
The biggest problem I encountered when setting this up with the SPR top rail, was the fact that the rail leaves no room for folding iron sights on the forend. With the shorter barrel, a barrel mounted front sight is also not an option because it would mount in the area between the Ops brake and the collar, where a suppressor is supposed to mount (Building this for a move out of state in about a year). Since the top rail mounts to a receiver height picatinny rail on the forend, I simply shortened it to leave enough room out front for the folding sight: The front end has been contoured to match the hooded post on the front sight for a minimal gap when folded: Build specs: Upper -PSA blem stripped upper -R-Guns NIB M-16 BCG -Rainier "Select" 14.5" stainless barrel in 300 BLK (Carbine gas) -PRI SPR top rail -PRI Gen III forend -Ops Inc. 12th model brake (Pinned and welded to bring the length to 16.25") -Spikes Tactical alignment collar (Had to have a .700" OD X 1.00" long step turned at the muzzle end to accomodate the Spikes collar) -KAC 600M rear sight -AIM Sports front sight (Looks like an alphabet block up there, but is actually a rock solid little sight) -BCM Gunfighter CH (Mod 3) -Caldwell/Blackhawk hybrid franken-bipod -1.25-4X24 Pride-Fowler Rapid Reticle 300 BLK scope in UTG Med QD rings Lower -Stag lower -RRA 2 stage trigger -Mil spec buffer, spring, and tube -B5 Systems SOPMOD Bravo stock -KZ 3QD end plate (Had to "turn" some extra threads on the buffer tube to get this to fit for installation, hence the fresh cut silver marks on the buffer tube) -Magpul MIAD grip/trigger guard (Soon to be replaced by a Sierra Precision grip and LWRC trigger guard) -Bullet button w/ 10/20 PMAG
