Night Vision WTS Envision MARSc 1550nm Ballistic LRF (IR laser, IR illuminator, vis laser)

I am selling my Envision MARSc 1550nm LRF, with built-in IR laser, IR illuminator, and visible laser. This is the commercial model, meaning the IR laser, illuminator and vis laser are not full-power. It does however have the 1550nm laser range finder of the FP MARS. I am the first owner and I bought it directly from Envision. The unit has been babied. I am selling it because over the last 12 months, I've had a chance to use it a grand total of about 4 times and the future isn't looking any better. Really hard to justify having it just sitting in the safe. It is a fantastic piece of kit and the best ballistic LRF I've ever used.

Everything pictured is included. I am missing the original manual, however Envision did tell me they can send out a replacement. If interested, just let me know and I'll arrange it. I do have the quick reference card.

Asking $9500 shipped, and please no trades. I am selling this unit because I have neither the time nor place to use it, with no end in sight. Any trade items would be in the exact same boat.

"Over Gassed" AR's Fact or Fiction? Other Perspectives

I see a lot of postings suggesting AR failure to feed malfunctions may be because their rifle is "Over Gassed" and I really have to question this. For backdrop, I have built up and test fired in excess of 500 AR-15's, many of them with custom or wildcat cartridges, and with a myriad of barrel lengths, gas system lengths, etc., where there was no recognized or normally accepted port sizing (had to figure it out).

One of the main arguments of the failure to feed malfunction as relates to "Over Gassing" is that the bolt carrier and bolt speed is too fast.

I have yet to see "Over Gassing" as a source of a failure to feed malfunction to be a real issue for a few reasons:

1. The speed of the carrier and bolt coming forward to feed a round is almost 100% governed by the stiffness of the buffer spring and the weight of the buffer.
2. If a rifle is "Over Gassed", that may speed up the retreat of the carrier and the unlocking of the bolt out of battery, but it does not per se speed up the carrier and bolt coming forward (i.e. the buffer typically hits the back of the buffer tube and the dead plastic end of the buffer softens that strike so it's not metal to metal, but it's not a trampoline effect, nor was an AR buffer system designed to do that).
3. An AR gas system is set up to bleed off all gas immediately after the bolt opens out of battery (i.e. it blows out the vent holes in the side of the carrier) so it's not like the system holds onto excess pressure to somehow convert that into carrier or bolt speed coming forward.

I am also not a big fan of adjustable gas blocks and I have seen plenty of issues with them (taken a bunch of them off customer guns a returned them because they were a source of a problem that did no exist). First off, an adjustable gas block is of no value at all unless the rifle is over ported. All an adjustable gas block can do is cut back the amount of gas being delivered into the gas system from the port, it can never add more than can come through the port. It may have some value for someone that wants to run something like a 300 BO where they want to shoot subsonic "heavies" with a real fast powder through a can to run very quiet (ergo they have a very large port to do that), but then wants to shoot supersonic and push bullets to the max where chamber pressures are running double what they are with a subsonic loading. Even then, what I typically see is an AR cycling back hard and ejecting aggressively but that's about it.

I have probably "opened a can of worms" here with this discussion but there are other perspectives on the issue involved.

Accessories Dometic CFX3 75DZ Dual Zone Cooler (Refrigerator/Freezer) with Cover

Up for sale is a Dometic CFX3 75DZ Dual Zone Cooler (Refrigerator and Freezer) with protective cover. It is in "like new" condition and was never used. This was because I was posted abroad for a couple of years and did not have access to it. I'm only selling this one because I no longer need it; the new trailer I bought has a cooler installed.

These coolers retail for over $1100 and the covers for them cost $179. I'm selling everything for: $700. It would be ideal for anyone who is involved in overlanding and/or going on extended self-supporting road trips for PRS/NRL matches, camping, hunting, etc.

I reside in Chapel Hill, North Carolina and would prefer to handle this sale in person. I have no problem driving a reasonable distance to drop it off. If a buyer wants the cooler shipped, all costs will be their responsibility.

Feel free to PM me with any questions/requests for additional photos.

Thanks for checking out my listing and have a good one! S/F!

SCAR as 6 ARC / 6G Platform?

IMG_2928.jpg



Anyone done a 6 ARC SCAR yet? Seems like the beefed-up SCAR bolt would do wonders compared to the more fragile retrofit design of forcing a standard AR15 bolt to accommodate a 6ARC case. While the JP one (pictured on right) does fine in one of my 6ARC builds, it clearly not designed for that large of a case head. Certainly, no engineer would design it like that on purpose.

On the other hand, the SCAR 16 is massively overbuild for 5.56 (as it was designed with multicaliber geometry in mind that never manifested as the SCAR 17/20 took over all the work), and seems like at the 6ARC case head dimensions it would be perfect. The SCAR also already has steel side rails inside the receiver for the cam pin, much like Geissele's SOCOM offering, intended to alleviate excessive wear from a larger-than-designed cartridge adapted to the AR platform.
