I have both a S&W M&P Sport and a S&W M&P 15-22. How much help in improving marksmanship, if any, do you think you get in shooting the Sport by practicing with the 15-22?
Also when I can find one I'm going to buy a S&W M&P TS. What kind of accuracy improvement, if any, should I expect when comparing the Sport to the TS? |

I think anytime you practice with a platform, you're going to see improvements. I built a dedicated .22LR upper in M4 config for this very reason, and to save some of my .223/5.56mm. While the 15-22s are awesome, I like the dedicated upper because I get time on the same trigger that I use with my 5.56mm upper.

The 15-22 is lighter than milspec, but the trigger on my 15-22 is almost identical to my other ARs. My factory triggers all have JP yellow springs. So the 15-22 and 5.56 ARs all have pull wieghts that are very close and feel the same. The 15-22 can accept milspec FCGs. I have optics my 15-22 set up very close to my 3 gun AR to help simulate 3 gun.
I find it to be great trigger practice. My 3 gun AR has a SJC Titan brake. So the recoil is greatly reduced. It is still more than the 15-22, but enough to feel like i benefit from practicing with the 15-22. I still train plenty with the 5.56, but i am able to put a few hundred rounds down range for a fraction of the cost. If i weren't able to shoot the 15-22, i would cut my training short. not just the 15-22. Any AR style 22 will help train. |

Lots of the benefit will derive at how you go about it.
Just blasting at tin cans ,not so much (unless your goal is blasting cans  )
If you are working on your position , breathing , hold or speed depending on what type of shooting you are interested in as long as you are tracking your results there will be much carry over from the rimfire to the centerfire. If the two guns are similar in weight , sights , setup and trigger it is all that much better but rifle shooting is still rifle shooting |
| I originally purchased my CMMG conversion for practice for Ft Benning 3 gun matches so I could ;use my game gun trigger... shot 800-1000 rounds of .22lr before 2009 and 2010.... after 2010 bought the dedicated .22lr upper... since then a local club is using .22lr for the long gun in a 3 gun format on a range with relative short 35y bays... using Team Challenge 2" and 4" steel vertical targets and paper, makes a fun match, at considerable savings with the inflated 5.56 prices... |

Sorry to somewhat hijack here but is running a 22 kit in your standard 556/223 upper cause any abnormal wear or problems as long as you are shooting quality 22 ammo? I shoot Federal bulk pack, over 10,000 rounds in the past two years, with no problems. Rim fire has to be much easier on the gun than 5.56. |

The difference in the Sport and TS will not be great enough for any real gains. And if you have the 1/8 5R Sport, you already have a solid, accurate AR. |
| thornejc.... no problems other than they make the action pretty dirty... before 2009 FB3G, I installed just the CMMG parkerized conversion unit, and shot about 900 rounds without cleaning... accuracy was not very good, no better than 2 1/2" at 50y, but acceptable for steel....upper around the gas tube and coating on the trigger group... lead buildup in the comp.... for 2010, since it is a blow back system, removed the front sight base and gas tube, covered the gas port with a screw clamp... much cleaner after 1100 rounds... after 2010, built the dedicated upper, BCG upper, CMMG .22lr barrel, fore end off the prize table... accuracy now rivals my STC 10/22 at 35y.... you may have to try a couple of different magazines... one of my original BlackDog transparent mags caused vertical stovepipe with the live round trapped between the charging handle and bolt face... others run fine |

My only complaint about the dedicated upper, or even a conversion, is they throw a ton of crap into the lower; specifically around the bolt catch and in the cavity that houses the fire control group. Just makes cleaning fun. You might want to look into the TACCOM pressure plug, which inserts into the buffer tube. It helps apply forward pressure on the .22 bolt group, reducing movement, wear on the lower receiver, etc.

As stated earlier, the benefit comes from working on marksmanship fundamentals like trigger and breath control, sight alignment, and so on. Any trigger time is good, but concentrated time working on whipping the muscle memory into shape is the real gold mine.
Yes, ANY .22 system, dedicated upper or conversion, will make your lower dirty. No real problem here, since it can give you more practice in detail cleaning your lower. Seriously, the BEST application of subcaliber training is to use exactly the same trigger and grip, so the the feel of everything is as close to the full caliber version as possible. |

With the lower, I spray it out with a water hose. Hit with aerosol CLP, give it a quick scrub with a toothbrush, spray it out with water again and dry it with the air hose. All the toothpicks and white glove bullshit is a waste of shooting time. Posted Via AR15.Com Mobile |
