    50 Shades of FDE - Let's see them.

    14.5" Criterion with P&W HUXWRX flash hider. Rogue Ops billet receiver set. Geissele MK 16 rail. JP FMOS bolt carrier group. Radian charging handle. TriggerTech Adaptable trigger set to 2.5 LB. BCM MK 2 recoil system. Nightforce NX8 in Reptilia mount.

    300Blk At Distance

    I wonder what the velocity increase would be using .300 BLK supersonic loads if the barrel had a 1x12 twist instead of the usual 1x7 twist.

    10.3 inch Geissele URGI Upper

    Agree with the above - The URG-I is pretty tough to beat. Throw a HUXWRX Flow 556K on it. You'll be pleased with the results. A friend has a 16" URG-I and a Flow 556K. I asked him if I could meet him at the range to see how it would do with a scope (NF NX8 2.5-20x50) and some match grade ammo...

    Envision MARS-M and M/C

    No - But I "envisioned" that they would be - All environmentals are frozen to Standard Day conditions. They can be overwritten manually, of course.

    Envision MARS-M and M/C

    Thanks for the input. The software in my Kestrel is too old to work with the MARS-Mc, unfortunately. Had to enter environmentals manually. Gotta pick a home for the pressure pad.

    Envision MARS-M and M/C

    So does this device generate its own environmentals, or do you need to input them?

    Another Picture Thread - All Other Semi-Autos

    Another ARS makeover, this time a "sorta" Dutch Clone. I skipped the Dutch sights because I want to shoot it with a Hensoldt Z24 on top, so don't blame ARS.

    12.5” Build recommendations.

    Look at the BCM MK 2 recoil system. I use a Craddock Bartlein 11.3" with carbine +1" gas system and a Geissele MK 16 10.5" rail on my LE-DMR. Nothing I own is more accurate. I'm sure a Craddock 12.5" would give similar results.

    Which scope for my Seekins SP10 6.5CM

    Imagine this Kahles K318i with Spuhr SP-4022C and Aimpoint ACRO P-2: On top of this custom SP-10:

    (Concluded) AR-15 Custom Build

    I put a Kahles K318i on a friend's Geissele Super Duty 5.56 recently, just to see how it would perform with a nice optic and match grade ammo. With Federal GM 73 Berger, it immediately produced sub-MOA five-shot groups at 100 yards, with the best coming in at 0.65". I'd get the 14.5" version...

    Which scope for my Seekins SP10 6.5CM

    I haven't bought a Leupold scope on almost 20 years. Back then, I had to return one out of every three for problems. Five years ago, I was hosting a group of Swedish SF guys here in the states. They had MK 5's on their AI's. I learned that - at least for my eyes - little had changed. Found...

    Which scope for my Seekins SP10 6.5CM

    I went with the NF ATACR 4-16x42 F1 on the 20" 6.5 CM I built, but later switched to the ATACR 4-20x50 F1. Here are some images of the 4-16x42:

    New Home Defense Rifle Suggestions

    Shooting indoors gets LOUD. Make sure whatever you get has a suppressor on the end.

    Should I buy a thermal fit upper or roll with what I have?

    Add 50 FT-LB of torque to the barrel nut and it won't be loose any more.

    Nightforce C538 NXS 2.5-10x24

    The NXS 2.5-10x32 and 2.5-10x42 were each successive improvements. But, the DOD in its inimitable fashion had already given the 2.5-10x24 NSN status. So, if in uniform, that's what you were going to get, unless open funds for outside purchase were available. Hence, the NXS 2.5-10x24 is the...

    Nightforce C538 NXS 2.5-10x24

    Nightforce has always made terrific optics. The NF NXS 2.5-10x24 was the very best in its class when introduced over 20 years ago. It's still a very desirable optic for clone builders - perhaps THE most. But, there are more capable choices available to us today. Example: For the same MRSP, you...

    Wanting to build 16" Recce but hung up on barrel choice

    V Seven barrels have always performed extremely well for me. They're quite nicely turned out, too. Handsome workmanship.
