No, there it is not dimpled for the gas block.
The Alpha Shooting Sports CHF 5.56 NATO Mid Spiral Fluted Barrel requires a .750 diameter gas block.
The manufacturer states that the Alpha Shooting Sports CHF 5.56 NATO Mid Spiral Fluted Barrels are machined in house. For specifics regarding the manufacturing of the Alpha Shooting Sports CHF 5.56 NATO Mid Spiral Fluted Barrels I recommend contacting Alpha Shooting Sports.
The Alpha Shooting Sports CHF 5.56 NATO Mid Spiral Fluted Barrels are machined in house from a premium cold hammer forged 416R stainless blank.
no they are QPD finished inside and out.... If you order the black barrel it is chrome molly valladium then QPD aka black nitride coated.
The stainless barrels are finished stainless with the same chamber treatment. Just an additional update the new barrels are now coming with a
NP3 coated chamber for those that used to come with a TiN chamber. Just spoke to the company rep to confirm.
The Alpha Shooting Sports CHF 5.56 NATO Mid Spiral Fluted Barrels are 16" in length and chambered in 5.56 NATO with a 1 to 8 twist.
Not simple the gas block, dimple the barrel so the gas block can be PROPERLY attached using a jig such as SLR that cost around $35 for each diameter barrel. So if your gas block journal on the barrel is .625, you need an SLR dimpling jig that is sized at .625. Dimpling is a process where using a jig ONLY(do NOT do the BS that people do in YouTube where the measure and TRY to align the gas blocks hole with the port hole in the barrel… use a PROPER JIG ONLY or you will probably RUIN YOUR BARREL!)such as SLR’s for example that PERFECTLY aligns the ports hole with the gas block to be mounted by using the jig that has a cone shaped sort of set screw that the point of it is tightened over the port hole in your barrel which PERFECTLY aligns the dimples or small drill holes that with the jig properly set up can use a drill press is best but hand drill can work but be sure to go in straight but do NOT drill to fast or deep since you could easily drill INTO the bore of the barrel rendering it useless trash. So you slowly drill one dimple or shallow divot at a time and constantly check it’s progress so you don’t go to deep and also go deep enough. The reason dimpling of ANY barrel is a MUST is the two set screws on the bottom will come loose and then the gas block will also come loose and will cause the gun to not be usable. After the dimples are done the two set screws that are all that holds the gas block in place since the two set screws actually fit perfectly into each divot so the gas block can’t come loose or lose its correct placement because the set screws and divots keeps the gas block from moving in any way. But you must use at least blue or red loctite and torque to PROPER specs which isn’t usually but around 15 inch pounds(not foot pounds so doesn’t take much). And worse case since the gas block gets extremely hot it could turn the red or blue loctite back into a liquid after it dries while shooting and potentially still come apart with proper torque applied even with proper dimpling done as well and in that case you use rockset(probably spelled wrong but if you google you’ll find it)which takes I THINK over three thousand degrees to turn the rockset back into liquid which would be the point it’d fail like I aforementioned about loctite in both red and blue. So tp clarify it’s a super simple process if you can use a hand drill and keep it straight as you drill. Also you must cool the cobalt or think it’s carbide drill bit that of your smart you make sure on the packaging it’s has labeling saying it’ll handle stainless steel and if it doesn’t do not waste your money, they won’t cut into hard barrel material without using a lot of bits. I use a cooling paste instead of a spray on liquid like I see people use WD-40 which is better than nothing but I highly suggest investing in a cutting paste as it works better and stays on the bits and surfaces to be cooled versus a liquid that immediately runs off the bit and barely stays on the surface to be drilled. I’m very handy, but using the SLR dimpling jigs and watching a few videos on YouTube as you should watch at least a few to find a couple that you can tell the person showing you how to use it truly gets how it works and how to tell you what to do. Hope this helps those who can do basic things with tools. If your not handy or feel like it may be an issue for you, I HIGHLY suggest paying a gun smith around $50 max(all I’d pay max for a FIVE MINUTE JOB!)to do the job or potentially you could be replacing your barrel that could be anywhere from $50 to thousands.
Yes, this will fire 5.56 NATO as well as .223 Remington.
MPN: ALPCHF16NIT556SF has a black nitride finish.
The type of barrel nut used will depend on the handguard that is used.
