The SN-ACH™ (Gen 2) (Suppressor Normalized Ambidextrous Charging Handle) is a patented, modernized, feature filled charging handle that will satisfy any AR15 user. The SN-ACH™ - Gen 2 features an improved gas check groove and an improved, forward-facing 60° gas vent that reduces gas in the face of the shooter when using a suppressor by ejecting it forward and to the side of the firearm. The revised Gen 2 SN-ACH™ also receives a beveled rear shoulder to capture gases escaping from the rear of the receiver and redirect them forward and to the sides instead of into the shooter's face. Improved fitment and machining of the Gen 2 SN-ACH™ creates a tighter seal between the handle and your upper receiver, resulting in decreased gas leakage at the rear of the receiver.
Configurable levers were also added so that a user could choose to run the included large lever, which works with gloved hands, or purchase and modularly use the smaller levers (available separately) without having to buy an entirely new handle at an excessive cost. The bolt carrier engaging hook features durable reinforced geometry for 30% increase in strength over milspec handles and approximately 3 times as strong as inferior 6061 handles which routinely break under hard use. Fitment bearing surfaces on the handle mating ensures reduced wobble fitment with the AR15 and AR10 upper receiver. The handle is made from 7075-T6 aluminum and hard coated for optimal wear resistance- the Griffin SN-ACH™ (Gen 2) is the finest charging handle available for the AR series family of firearms.
SN-ACH™ 15: Fits all typical AR-15/M-4/M16 family firearms (1.3 oz weight)
SN-ACH™ 10: Fits Armalite AR10, KAC SR25/M110, DPMS LR308 rifles and rifles with SR-25/AR10/LR-308 compatible charging handles.
SN-ACH™ 9: Fits conventional nose geometry of standard 9mm BCGS (ex. Colt/direct blowback AR9s). It can also be used with an AR15 as it is an AR15 handle without our nose reinforcement, which inhibits compatibility with 9mm Colt BCGs.
Terra Brown Anodized Color Note: While we strive for consistency in the color of these components, there are some inherent differences in final color outcome that are out of our control due to the anodizing process which depend on many process parameters such as material alloy (6061 (Rails, optic mounts) 7075 (upper/lower receivers, charging handles, receiver extensions), material heat/lot, material process (extrusion, forging, impact extrusion, etc), material condition raw or machined/cut, anodizing water process temperature, acid etch time, rinse speed and time, dye concentration, anodize time, current intensity, blasting media condition, blasting angle variation, etc. This is well known at this point among consumers in the industry with "fifty shades of FDE" colloquialisms describing the variations in color possible in anodizing of colors lighter than black. The product you receive may be a somewhat different color than what is pictured due to these aforementioned variables in the electro-chemical process. Additionally, small cosmetic imperfections usually hidden by the black anodizing process are more easily seen due to the lighter pigment of the Terra Brown dye. Because these issues are inherent to the process, slight cosmetic imperfections may not be pulled from inventory and marked as a blem. This is a risk of purchasing a non-black product and should be expected to a degree. We will not sacrifice the functional performance of our products, and any issue that affects performance will not be sold. Anodizing fortunately doesn't have the level of increased cost premium associated with the intensive labor involved in painting rifles (something we simply don't have the available labor pool locally to support, nor do we believe the customers want to pay the premium for), so color being possible in that atmosphere at no additional cost is a major process benefit of anodizing. If the above mentioned conditions are unacceptable to you, we encourage you to purchase black anodized parts.
Just got it in installed it on my colt m4. It fits works great. It's just the right size. Not overly large like some. But bigger then the standard mill. I'm left handed and the release it great. I don't need to over force the release like some left handed models. It's just smooth to operate. I have not used it with a silencer yet. So not sure how well is will block gas. But it sure looks like it will do the job.
Charging handle has worked great as advertised. I switched from another highly known charging handle and was impressed with the difference in gas mitigation under suppressed use in my Geissele. My only question would be if it’s possible to have an option for lefties with the gas ejection port being on the left side, while retaining the same locking mechanism except reverse. It’s a lot to ask, but it would really help perfect a problem I know many other lefties are also combating. Besides that it’s a 10/10 for me.
I had the Gen 1 and it was kind of a tossup for performance between that and my Raptor, but the Gen 2 beats out the Raptor pretty handily. Super tight fit, but breaks in nicely after a few mags, definitely helps seal in gas better than the Gen 1. For a hundred bucks it's hard to justify getting anything else.
my build is a 20inch Stealth 556 LaRue with All part Larue inclu quadrail. I purhased and currently use the PSR7. to interchange between my 308 and 556. spent 2 days at range this weekend. 500+ rnds, of my own reloads. I changed out the Charging handle from my Raptor SD and this one, after 1 day. So i had 2 days back to back - 1 with Radion and 1 with Griffin. Hands down, cyclic of operations andGas blow back- This one worked better! will now be my go-to. ..i could use longer handles, but itsonly because i am handicap due to an IED in Afghan. I assure you, give this a try. Cheers from the Woods of Maine! USMC 0369 Ret.
They work fine in my more economical builds. In a couple upper end billet builds, the ridge on top of the handle prevents it from seating or functioning. I was informed that these are designed to operate in standard mil-spec equipment. So, if you have higher end gear with tighter tolerances, stick with the Gen 1.
The gen 1s were good, but I think the improvements in the gen 2s not only make sense on paper, but the taper for the rear of the charging handle does create a better seal when shooting suppressed. Also the 60 degree vs 90 degree just makes sense. Recommended.
