Sintercore Teases 15-22 Charging Handle

Despite thousands upon thousands of units sold, the aftermarket for the 15-22 has languished a hair, likely due to Smith & Wesson keeping much of the mounting and interface proprietary. Its well know the difficulty trying to get standard handguards to interface flush with the receiver, with only various options able to slide back across the gap with the barrel nut adapters in place.

Perhaps most annoying for everyone using the 15-22 as a true training tool has been the lack of charging handles. While a few companies have stepped up like Next Level Armament, the “major” charging handle players have kept their offerings limited to the “big boy” rifles.

Fortunately, this leaves room for small companies to fill in niches. Seeing a market hole is Sintercore, known for their Tripwire charging handles, which I previously reviewed a few years ago. Seeing the 15-22 crowd woefully underserved, Sintercore has announced they will soon offer the Tripwire 15-22 with the characteristic latch-free design.

Features from the “big boy” will stay consistent including construction from 7075-T6 aluminum, weighing in at less than 1 ounce, and an “engineering grade” thermoplastic latch. Color options include various Cerakote Elite colors like Concrete (Grey), Earth (Brown), Jungle (ACU Green), Sand (Tan), and Midnight (Black).

Special pre-order pricing is currently live on their website. Those interested in upgrading their 15-22 will only pay $50 retail with pre-orders at $45.

    Doesn’t the guy behind these post here regularly? If I’m thinking of the same guy, he seems like a good dude. I hope this does well for him, if I had a 15-22 my left-handed self would be getting one.

    • Neal – Sintercore

      I try to. Thanks for the support. 🙂 If you ever buy a 15-22, hit me up and I’ll send you a handle.

        Just bought one. I’m a lefty and dislike the OEM configuration. I hope this makes it more fun to shot. I also like the reputation of the company. Forgot to order the free shirt. I sent them an email after the fact. I hope they accommodate

        • imtoomuch

          • Neal – Sintercore owner

            Go to the mission / about us page and click the picture link about mil / LE / first responder discount. Free shirts and 5% discount to anyone who qualifies. I hooked Tomcat up with a shirt even after he ordered. If anybody else missed it, feel free to contact me at

      • Cymond

        Hey, I’m the dude who contacted you a few months ago, and you sent me the updated Tripwire latch spring.
        It works like a charm, and I would buy one of these if I had a 15-22. Instead, I’ll probably order your retrofit latch and use it on my CMMG rimfire charging handle.

        • Neal – Sintercore owner

          Awesome! Glad to hear it. 🙂 Before you order, email me with your tshirt size so I can send you one. Thanks for the support.

    If you want a “true training tool”, just get a .22 CMMG upper, and use the stock charging handle (and other bits).

    • Audie Bakerson

      Cheapest that goes for is over 500 USD. Brand new 10-22 is sub 400

      • And the 15-22 is more reliable than any 22LR conversion upper I’ve seen.

        • int19h

          15-22 is still banned from Appleseed due to dangerous malfunctions, no?

          • topcat

            I don’t know if they are still banned but I called S&W the day after I first read about this on TFB and they denied they had a problem . They said they have no plans on a recall or providing any advice on the matter . I had a warranty problem when the extractor blew out and the bolt carrier cracked. They put a new extractor and spring in and sent it back with the cracked bolt carrier. Sent it back again and they repaired it. But why did I have to send it back twice. Poor aftermarket QC but good customer service. They were prompt and courteous.

          • Tom Currie

            It is worth noting that ONLY Appleseed reported these problems. They reported a total of four incidents – all on high usage rifles – and those four incidents were two totally different problems. AND, perhaps most important, at least one of those two problems indicated a complete lack of the shooter inspecting the rifle (even casually). Here’s a hint from the AR world that apparently also applies to the 15-22 — if you have a pin sticking out of the side of your lower receiver in the area of the fire control group, you should probably take a closer look, and maybe even push the pin back in place.

      • int19h

        Well, if you want a true training tool, you gotta pay…

        • Audie Bakerson

          I don’t know about you, but 1000+ extra rounds (likely 1500 or more given the CMMG upper has no sights or magazine) to shoot seems like a better training tool than a slightly nicer gun.

          • int19h

            CMMG upper that I have came with the standard A2 front sight and 1 mag.

            Anyway, by that metric, a better training tool in general is 10/22 – you can get even more extra rounds with that, and it’ll teach you the basics just the same.

          • Audie Bakerson

            15-22 has the same controls and erogonomics as an AR-15. Yet to hear what justifies the extra cost from a CMMG upper beyond charging handle.

          • Cap’n Mike

            With the CMMG, you can use your real lower along with its aftermarket trigger, grip, BAD lever, ambi safety, sling mount, folding stock, etc.

            If you have an SBRd lower, CMMG has a 10 inch upper available also.

      • Mark

        CMMG .22 Bolt conversion for the AR is sub 200 and seems to work pretty well.
