    V seven Rifles?

    Standard statement: There's a lot going on with shooting large frames accurately... techniques from precision bolt do not always translate in to (lighter) gassers. I cannot speak to your particular barrel, but some of my most accurate builds have been based on the same blanks. But every...

    What’s the shortest mid length gas system for a ar15 that will run suppressed?

    What does reliable mean? 200 rounds between cleanings? 2000? I run high back pressure cans. I tune to those, as a rule. The shorter the dwell (distance between port and open venting post projectile leaving the unsuppressed muzzle) the more open the gas port to add enough energy to the...

    What’s the shortest mid length gas system for a ar15 that will run suppressed?

    If your running suppressed, you shouldn't have any trouble with an 11.5" midi (using pretty standard parts.) Cant go too much shorter, as there isn't a whole lot of barrel left after the gas block for threading.

    V seven Rifles?

    Given a choice, I'd build everything with V7 matched sets, handguards, and extension.... trigger, barrel and reciprocating systems are preference / purpose driven. My personal 6.5C and 223 are both full V7 bodies. I haven't seen all the sets in the world, but I've never one nicer then a...

    What blast can or linear comp for mini Draco

    I'm a big fan of the design of the SLR. There's a lot more going on inside than meets the eye.

    Advice on new AR-10, learning precision shooting

    I get plenty of feedback on my technique shooting (relatively) inexpensive handloads (52gr Hornaday OTM, CCI 400, whatever powder to just less than compressed load) out of my 223/556/whatever at 100. Mistakes are obvious, even with loads that aren't super dialed. Shooting at 100 eats up the...

    Advice on new AR-10, learning precision shooting

    I've seen a handful of PSA builds that run just fine. - My bias leans heavily towards gassers, for all sub magnum applications. - How much time do you have working on your fundamentals? Less expensive rounds with more forgiving platform may provide a better opportunity to diagnose technique...

    Top tier vs mid tier lower

    Lowers need to hold the parts in the right places. Uppers have to keep the optic and the barrel aligned. Upper and lower fitment might be super important in precision. But that's a matter of fitment (matched sets, or whatever magic you want to employ).

    Rifle Scopes Reptilia mount with a 50mm objective

    I wouldn't describe it as bulky, but that's my impression from the flat range. I don't have any experience hiking with it in field conditions. Personally, it wouldn't hold me back.

    Rifle Scopes Reptilia mount with a 50mm objective

    Either config would work then. If I wasn't running at 12:00, I would be biased to running my red dot offset on the same plane as my magnified optic. I have a few hundred rounds on carbine on the second config (Arisaka, etc.) and I find it to be very intuitive and easy to align the dot to the...

    Rifle Scopes Reptilia mount with a 50mm objective

    It was necessary to use the riser to clear the elevation turret at 12:00. I should have asked your application. Most of my builds are biased towards longer range precision. The guys that are set up for 2-gun/3-gun seem to like the offset that runs at the same plane as the magnified optic, so...

    Rifle Scopes Reptilia mount with a 50mm objective

    I have an Reptilla RMR mount on a Vortex LHT SFP 3-15 mounted at 12:00. I ended up picking Reptilla's larger riser, and then removing material until the base of the RD lens was level with the turret top. I'm biased towards the 12:00 position. I find it convenient for quicker and closer...

    Is this a good budget Ar-15 ?

    It is just fine for what it is. I wouldn't get captured by the price point. There are lots of available full builds at low price points. The challenge seems to have been finding particular parts.

    Weird issues with AR10 build

    You might be over-gassed. My only experience with PMC Bronze were chambered in 223. I found it to be a low pressure loading with lots of velocity variation over the chrono. If that is the case in their 308 offering, you might be running a light projectile with low pressure gas. In an...

    Enhanced BCG"s for shorter barrels?

    Bootleg BCG sample size of one. Experimented with carbine gas, 11.5" Rosco, Superlative adjustable gas block. Tuned to a mid-high back pressure can, I couldn't run unsuppressed from the BCG adjustments alone. Manufacturing details seemed very good (it's not in front of me, so I can't go into...

    7.62x39 upper fails to eject

    What info do you have on the upper? Do you have access to micrometers? (Your cases might be blowing out from a large chamber not offering support to the case.) What info do you have on the BCG / Buffer / Spring rates? Extraction is a combination of force and timing. Changing one will not...

    Stiffer uppers ?

    I'd suggest you review your technique. How did you rest your rifle when not using the bipod? There are other dynamics involved in positional shooting that can result in shifting POI.

    Weird issues with AR10 build

    What weight projectiles? Lighter weight projectiles typically allows for higher system pressures at gas port. If you're shooting 150s vs 168GMM, you might just not have enough poop with that short of a dwell before uncorking. If so, loose some weight in the BCG+buffer world, or--my...

    School me on light weight ARs

    What's your intended use? If it's precision, your stacking the deck against yourself. If it's just for fun and speed, guys can usually make UL builds work. Adjustable Gas Block? Yes. Your talking about building your gun around parts your barrel port size was not designed for. Adjustable...
