I hear these are the scope mounts the area force can be getting on their modified HK G11s.
past this 12 months, Black Collar fingers, in part owned via TTAG’s own Jeremy S, released their extremely-premium one piece forged carbon fiber scope mounts. These mounts are made for Black Collar via McVick manufacturing out of Oklahoma.
It’s lauded because the equal know-how developed with the aid of Lamborghini and used in a few key components of their cars in addition to via Calloway Golf in their membership heads. I don’t care. I’m not a car dude and golf is a good walk spoiled.
but a cool looking, rock-solid scope mount that only weighs 5.4oz? Jeremy, sir, you’ve got my consideration. And no, that’s no longer a misprint. The mount weights a mere 5.4oz.
I don’t basically just like the term “solid” for this category of producing, but I don’t be aware of what else exactly to name it. That’s what Black Collar calls it, and it’s different sufficient from the layering and wrapping pattern we see with other carbon fiber objects to just leave it at “forged” and speak to it a day.
When it comes to durability, there should still have under no circumstances been any query about the mounts. essential materials science would clarify that these mounts might be as or more durable than different top rate mounts on the market.
When Jeremy advised me his plans to bash a superbly decent scope so as to show the mounts have been good, I expressed the opinion that this event would show little. in any case, wise people already knew the scope itself is the weak link, and dull americans would nonetheless be stupid. So there were zero surprises when, after destroying a scope by smashing it with a mallet, the tube bent, the bell broke, and the mount confirmed no signals of damage.
durability was by no means a real challenge, but there are different considerations.
one of the crucial problems with carbon fiber is that other materials have to have interaction with it, and mixing very diverse substances all the time gifts challenges. one of the vital obvious of those is the screws that grasp the rings collectively and the screws that affix the mount to the receiver. these screws are steel, and over time metallic screws are likely to route out thread holes in carbon fiber objects.
within the case of the ring caps on the ring bases, the answer supplied by using McVick is to insert metallic thread sleeves into the physique. These are screwed into from the accurate, however via a simple steel bracket.
The mount is held to the receiver based on a typical 1913 Picatinny rail and locks down with 4 screws. basic washers maintain an outstanding, even power on the squeezy components.
To examine how well these combined materials play with every different, I carried out a chronic, however notably effortless examine. I torqued the ring caps to 17 inch-kilos and set the mount in a deep freeze. someday all through the day, I took it out and measured it with my Brown and Sharpe calipers. I did this daily for a month.
Physics is physics, and different metals extend and contract in a different way. That referred to, the use of my manual calipers, i used to be no longer in a position to verify any difference in top, length, or width, ring diameter, or another dimension I could think of when the rings had been frozen vs. thawed.
The widest temperature range from frozen to thawed over that month turned into actually over one hundred degrees. When the mount wasn’t within the freezer, I simply set it backyard. It didn’t rain that month (at all), nonetheless it did get lots of sun. No hurt was obvious.
I also set an AR-15 SBR higher receiver with the mount attached interior the freezer. The consequences were the identical as with each different mount I’ve ever put on some other AR receiver, however with a moderate twist.
the primary time I did it, I carried out my commonplace check mount practice of turning a torx wrench in opposition t the screws except it felt like i was going to bend the wrench. That grew to become out to be at 34 inch-pounds. i know that as a result of in any case of the checking out was accomplished I received the common container and found that the base screws had been purported to be tightened to 25 inch-kilos. So I did a short verify before backing the screws out to where they belonged.
At 34 inch-kilos, I pulled the receiver from the freezer, gave the mount a robust whack with a rubber mallet, and measured the circulate. probably it moved 1,000th of an inch. probably.
once I backed off to the appropriate base screw torque score and repeated the freeze/thaw/mallet test, the mount moved to the returned of the rail area. I did the equal element, but waited except both had thawed. No discernable flow. here’s what i am used to with different mounts. lengthy story short, examine your mount if you are in bad 30 degree climate for 10 or extra hours. additionally, reconsider your life choices.
considering I’m nonetheless now not in a position to circulate round too plenty from my fresh nephrectomy, I requested a friend of mine to do some shooting. First turned into 200 rounds through a .458 SOCOM rifle. (I offered the ammo. Ouch.) This became with a Nightforce SHV 3-10X42mm scope established within the rings. He then eliminated the scope and mount and put it on a bolt action rifle chambered in .308 Winchester.
Neither rifle moved the scope in the rings. The rings additionally didn’t scratch, discolor, or otherwise mar the scope or the AR-15 receiver. That become a particularly great feature.
I also wanted to see how round the rings had been, or to peer in the event that they obligatory gigantic lapping. when I set the 30mm lapping bar within the rings, i spotted there became somewhat of room on the facet. Measuring the closed, however not torqued tight rings, I found they measured 30.5mm, and that they weren’t reasonably perfectly circular. Torqued all the technique to 17 lbs., they had been greater circular, however nonetheless not ideal.
With a scope in the rings, and torqued tight, i used to be unable to locate any hole anyplace with a feeler gauge at even 1,000th of an inch. i attempted this with a Leupold 30mm scope that really measured 29.93mm as well as a Vortex 30mm scope that measured 29.95mm.
I suspected the reply, but got in touch with the company, Mr. McVick himself, to seek advice from him about why the rings had been a bit outsized and not completely circular. The answer is fundamental; carbon fiber doesn’t flex like aluminum.
As I found once I torqued the rings right down to the appropriate spec, they snugged up tight in opposition t the slightly undersized tubes. Mr. McVick left the rings somewhat outsized in order that they wouldn’t mark or crush the tubes beneath them. I don’t care if my scope is marked by way of the rings. Heck, it’s doubtless going to get all rattle-canned up anyway, but I take into account if others do.
Between the months of testing I’ve put into these rings, including 30 distinct freeze/thaw cycles, as well because the ridiculous exams Jeremy put it via, I’d say any true considerations with these mounts have been put to rest.
What we are left with are in reality cool looking mounts that get up to make use of and abuse in a wide range of temperatures. They take a beating. They also do everything a top quality mount is meant to do. They hold the scope in vicinity, and do it with the added benefit of now not marking up the tube or the receiver. The huge improvement is the fact that these mounts have a full footprint, with lots of ring contact, and weigh next to nothing.
