    Gas vs mass tuning?

    Fo4 small frame ARs... Lowering mass and gas lowers the shake weight effect... the chunck, chunk of the moving mass rocking the gun. The downside is a bigger variance when shooting suppressed and less mass and power to push through fouling when dirty and decreased amount of fouling or cold to...

    moa vs mils, the forbidden thread

    FACT: Mils can also just be thought of as 1/3 MOA clicks if you are an MOA guy. FACT: Mathematically, 0.1 mils is closer to 1/3 MOA than 1/4 MOA is to a quarter of an inch. I am a simple minded American shooter so I prefer yards and mils. I'm an American, so think in yards, not meters. In the...

    Where do you measure a LR308 barrel to determine gas system length?

    My gas system from front of receiver to back of gas block is 12.925" best I can measure. With a new AR10 15.5" gas tube from Wilson Combat, my gas tube protrudes 1.1" to 1.125" into the receiver. It certainly seems I have a gas system about 0.1" shorter than true AR10 length. This is causing my...

    Looking for a 45 degree Ar15 safety switch

    Check out V Seven safeties. I prefer their 57 degree because it puts the lever at just the right angle for me to easily put it back on safe without having to move my grip. If you find it too stiff, cut a single coil off the safety spring at a time to get the stiffness where you like. I remove...

    Where do you measure a LR308 barrel to determine gas system length?

    I am well aware of the different gas tube lengths and those stats are easy to find. I presume the gas system diagrams show AR15 gas system lengths correct? Per the response with gas tube termination relative to the cam pin cutout... I am using the 2A Xanthos upper. The cut out for the cam pin...

    Where do you measure a LR308 barrel to determine gas system length?

    I have a Wilson Combat 6.5 Creedmoor barrel I highly suspect is 3/16" longer than AR15 rifle gas length and 3/16" of an inch shorter than AR10 rifle gas. I assume I measure from tbe center of the gas port to where exactly? And what should that measurement be for a LR308 barrel for each gas...

    Throat erosion and chasing lands

    Just ensure you are broken in and find the node for seating depth. Use the absolute shortest jump that is still in the node before it falls apart. Now you will just get into the middle of the node and end of the node over your barrel's life. No need to chase lands since you are still in the...

    Too Many Barrels... I Am Lost

    For anyone researching this topic, I would skimp anywhere possible and put ALL possible money into the barrel for your first precision build. Cheap bolt carrier, standard charging handle, cheap lower parts kit, etc. The key to barrel price is NOT going fluted. Fluting makes hitting your weight...

    AR15 lock back ammo sensitive?

    Your very heavy spring and buffer combo combined with your gas port appears to be ideal for suppressed and undergassed for non suppressed... or over sprung and buffered for your gas port size unsuppressed... depending which way you want to look at it. I tune my rifles for light buffer, light...

    3 Section vs. 4 Section Tripods...

    To me, the whole point of spending the money on a RRS tripod is to have a usable 4th leg section. I have cheap (in comparison) Chicom 4 section CF tripod I use for my spotting scope which is perfectly stable for any use with just three of the leg sections extended, but TOTALLY useless for...

    AR Accuracy: What to Expect and How to Acheive it?

    I have a lightweight precision .223 AR 15 and if I don't wrap my thumb and use a slow squeeze it bump fires from the shoulder. You must hold the grip and have good trigger follow through if you don't have a 10+ pound semi auto. Free recoil and no thumb wrap = bump fire.

    Rifle Scopes Lightweight LPVO recommendation for AR pistol.

    Easy... lighter than all the options mentioned above: Leupold VX5HD 1-5×24 with Firedot reticle and CDS ZL2 locking turret with custom BDC for your favored 300 BLK load. At 14.7 oz you wont get an illuminated reticle 1x capable scope that is lighter than pretty much all other illuminated 1x...

    CLE match AR15 chamber issues and questions

    So I purchased a full custom Bartlein 1/7.7 CLE match chambered barrel as part of a lightweight precision build. While this used to be advertised as a 5.56 match chamber it is clearly a .223 chamber due to the very short freebore. It shoots anything...

    Best spotting scope tripod head?

    I use a SLIK AF2100 pistol grip head. Makes aiming easy with a red dot zeroed to the spotter and holds still once released. Very small adjustments are difficult if you need that. But if you need a solid hold and easy/fast aiming it works better than Manfroto grip head. It is a bit heavy though...
