.22LR trainer: conversion bolt vs dedicated upper vs 15-22
As the title suggests, I am looking at getting a 22lr for the sole purpose of cost-effective training to acquire skill with my ar-15. I'm looking at all the different options, and would like feedback from those who have already gone down this road.
My current thinking is to buy the CMMG conversion bolt, a few cmmg/blackdog mags, and the Borebuddy reliability upgrades. I'll also be getting a Primary Arms red dot that I will zero for 22lr. That should allow me to switch fairly quickly at the range between 5.56/.22lr, and the handling characteristics would be identical to my normal AR except for no recoil.
Down the line I figure that I will buy a 22lr barrel and collar to improve the accuracy and turn my upper into a dedicated .22lr upper. That would happen after I build a 2nd 5.56 upper, which at current prices I could afford to do after shooting <2000 rounds of 22lr instead of .223. That is my thought process / justification.
The S&W M&P 15-22 seems like it will be the most reliable and easiest solution. However, by the time I buy furniture and a trigger to replicate my real gun, the cost would be the same as buying the conversion kit and then a complete upper down the road. For all that it will be much lighter and balanced differently so I don't feel it will translate over to 5.56 skill as easily.
Thoughts/suggestions?
S&W AR-15-22 in .22 LR caliber
I bought an S&W 15-22 in November of 2009.
I used various models of the M-16 in the service, and have accumulated a number of them since. My first was an SP1 that I bought in 1977.
I bought an Atchisson converter back in 1982 from Bro-Caliber International. I couldn't get it to work at all until I had it tuned by John Norrell in Florida late in 1985. After that, it worked GREAT and has been very reliable and NOT ammo sensitive.
The converter works well, but I was interested in the Colt and Smith & Wesson ARs in .22 as soon as they came out. I have a friend who bought one of the Colt .22s, and I shot it and enjoyed it, but it's complicated to disassemble to clean and the external controls don't work the same as on a "real" AR -- in particular, the bolt catch/release doesn't work at all, and the safety works differently than on the original rifle.
So I bought the S&W M&P 15-22. Best function has been with CCI Mini-Mags or the CCI AR Tactical Rimfire ammo, but if kept clean and lubricated the gun works fine with standard velocity LRN .22. After I had the gun a couple of months, I was firing Winchester Expert .22 ammo and had a round go off out-of-battery. It blew the extractor off. The case was ruptured. We found the case, but not the extractor.
The guy at S&W customer service said that was a common problem at that time (2010). I shipped the gun back (at their expense) and they repaired it and I had it back in two weeks or so.
A few years ago I got a Safariland RLS light & mount to put on the rail of my M&P 15-22. It attaches on the rail at the 9 o’clock position, and the mount curls up and puts the light at about 11 o’clock, which is a convenient place for me to activate the tail cap switch with the thumb of my left hand.
I just got a Vortex Crossfire RDS to put on that gun, but I haven't mounted it yet.
I’ve been real happy with the M&P 15-22 and I’d recommend them to anybody.
