Not even sure I should post this here. But just put a dedicated .22 together and it is great. Dead Air Mask suppressor,HT SS, 9 Inch CMMG dedicated barrel, CMMG stainless Bolt group with bore buddy buffer in behind the bolt, Bore buddy pressure plug. Bore buddy enhanced firing pin that Bore buddy gifted me a couple years back. Bore buddy adjustable trip..It required absolutely no adjusting, running it as it came with the adjuster screw all the way in. Bore buddy deluxe weight kit. I have the aluminum body and the steel one. I am running the steel one with two large steel weights, and one short steel. Perfect combo for me. HF Super safety and I used the little centering block that came with the SS. Some do not like the push button safety, I actually like it and it has its own advantages in my opinion..I have used cross bolt safety's in many Firearm's. Fine with me. I have only had it together since yesterday. So have only ran some BD 50 drums, and BD 25s in it.. Combination of CCI SV, and CCI Mini Mags.. Probably 250 rounds through today and both mags and ammo combos run absolutely flawless. Perfect function, feeding and ejection all around. I did alot reading before I assembled this and there is a list I found of combos that have worked for people, with varying barrel lengths, trips, suppressed or not, weights used. The setup from one guy that pertained to my 9 Inch suppressed barrel was spot on.. I was actually pleasantly surprised it runs both CCI SV, CCI Mini Mags with the same setup. But CCI is the only brand of .22 ammo I use.Use junk ammo and get bad results every time..CCI is the one and only ammo that runs perfect in all my Rimfires. Very happy with the results today.. I never expected it would run flawless the first time out..But it does.. I had a Binary before this. It was OK, but I like this alot more. I have no desire to use a SS in a 5.56 whatsoever. But in a .22, it is a heck of alot of fun, and a lot cheaper too, by far. Maybe this will help someone with a similar setup and ambitions. Older photo with he Binary still in there. But still set up identical..I love the old IDF surplus Meprolights..Though the tritium is pretty good in it yet,The add on illuminator makes them a near flawless optic in my opinion..  |

Thanks, hope it helps others. One thing and it is not that important that I forgot. I used small pieces of cotton balls in the weight setup to dampen the loose fitting weights, so they do not rattle and bang around, and beat the inside of the weight housing so much. This a chart I found that sure helped me a lot to get this going on the first try. https://docs.google.com/spreadsheets/u/0/d/1PoH4bVs8oBfhm8XSMY9-z-KF1B3k2SwDW4jW551cEkA/htmlview?pli=1 |

For me, this has been as close as one can get to 100% function shooting 22lr IMHO. I get an occasional stove pipe, random dead trigger/light primer strike or failure to feed... Hell I would get those running slow semi  I have had range trips where I went thru a brick or more FRT without a single failure... There is a large thread in the "rate of fire triggers" sub forum devoted to 22lr FRT. https://www.ar15.com/forums/AR-15/Who-here-is-using-a-FRT-with-a-22LR-What-is-your-setup-/130-790783/ |

Curious, happen to remember what ammo you were using. As I said in my original post. Only CCI in every .22 I have..I have bought many projects that people said were a piece of crap..Nine out of ten times. I found out when asking them. Oh I usually just shoot the cheapest crap on the shelf. Their in lies the problem. Shoot crap like Winchester, Federal, Rem and it is going to be a failure. After 250 rounds with no failures so far..I do not anticipate any failures at any kind high rate at all..I expect if they do start happening. It will be because of the Firearm getting dirtier than I should have allowed it.. Mine always ran flawless with eh Binary too. Fine tuning the Bolt weight to eliminate all bolt bounce is essential to 100 percent operation also. That one causes alot of problems too. One other thing I did not mention, and it is a big one. The SS lever paddle has to be free from any friction or binding. I clipped about three coils off the selector spring until the paddle almost flopped freely back and forth.. Also the next biggest thing I see in self induced problems in .22s, is if a 1/2 a quart of oil lube is good..When it starts malfunctioning from the wet lube attracting all the dirty trash left behind by the dirty nature of .22 ammo..Their solution is to add another quart. I run all my .22s dry. Only exception might be some occasional dry lube..But never often. Cheap ammo, wet lube and lack of maintenance accounts for 99 percent of self induced problems in the .22 Rimfire platform. Not just in AR22s, but all .22 rimfires. Ammo quality, and the use of liquid lube, is often the most overlooked major woes of .22 rimfire failures.. Keep your 10-w40 for the big boys.Use it in a .22 rimfire..Live with the problems. I collect Berettas and have around ten in 22 rimfire..With CCI ammo and no lube. They are as reliable as can be.. Some of this stuff I learned from extensive reading on another website from those that have actually got them to run 100 percent. They did the hard part for me. |

Some of this stuff I learned from extensive reading on another website from those that have actually got them to run 100 percent. They did the hard part for me. I do mostly shoot older, Federal red box bulk pack purchased at Walmart. No, it's not great ammo but has been trouble free enough. At 3-4 cents per rd, I don't mind occasional hiccups. It also stays subsonic from my 4.5" barrel. Mini mag will still go super depending on atmospheric conditions. Even though I always wear ear pro, even when shooting suppressed, I prefer no sonic crack. EDIT; I should have added I have shot, CCI blazer, CCI SV, Aguila SV and some Norma tac-22 FRT. They all did pretty well with proper tuning for me... I'm not shooting SK, Lapua, ELEY etc. FRT, bolt guns sure, not mag dumping steel... Tuning is very important. Anti bounce weight, recoil spring rate and even changes as small as extractor/firing pin spring rate can make a big difference. Like you, I also weakened the selector detent spring to reduce friction for the SS. Polishing the trigger tail and shimming the SS lever forward to get better timing helped as well. The MARC I currently use has even less friction than the SS. Timing is one thing that the lever type FRT'S will never be good at...if you're not careful with trigger pressure you will advance timing and send the hammer early. Cleanliness and lube, also very important! I clean every range trip, exception would be if for whatever reason I only fired a handful of mags. Detail cleaning is also important, FP and channel often get overlooked and these get filthy quick especially when shooting suppressed. Same with the extractor. Lube, yeah...with 22lr wetter just creates more slurry! I use Hornady one shot clean and lube. It's a dry film lube, no slurry and carbon/powder residue doesn't stick to it or get under it. makes cleaning easier, build up basically wipes off. WD40 specialist dry lube is another decent choice but I find the Hornady is a little better lube. I don't use either for cleaning... Keeping your mags clean is another often overlooked issue. I mostly use BDM mags with some CMMG and AU mags in the mix. All of them need an occasional warm soapy water bath. I use dawn because its what we use for dishes. Pull the spring, use a small bottle type brush to get inside the body, sponge wash/rinse the rest. Keeping that sticky, gummy carbon/powder residue build-up limited helps keep things feeding well. Bullet lube build-up in the mag can also cause feeding issues and needs to be limited just like carbon/powder residue. |

I have a pile of CCI Blazer here. I really do not like it..But I ran 50 rounds through today..And it functioned flawlessly for me..I was really surprised as I have had problems with it in other semi autos. I was looking for somewhere to get rid of those Blazers,LOL This will be it..The blazers are the bottom of the varrel in my opinion for CCI ammo. Yes liquid lube just creates a serious slurry of sludge in a .22, even with just a small amount shot through. The Hornady is good dry lube..Only wet lube I ever use is a very tiny small drop on the extractor and firing pin.. I am just running the stock recoil spring that came with the CMMG BCG.. And the stock firing pin spring too. |
