I am having a hard time deciding between Spikes new conversion kit or a dedicated upper.
What are the pluses and minuses to each? Does shooting a lot of .22 through your go-to AR wear the barrel prematurely? Is lead or gas fouling an issue? Is .22 through a 1/9 or 1/7 twist a problem? Thanks for the advice! |

Barrel wear is a non-issue with .22LR. .22s are inherently dirty, as are most blowback arms. I think the gas tube fouling can be cured by firing a magazine of 5.56. A dedicated upper will be more accurate because of (1) proper bore size, (2) proper rifling twist rate, and (3) no jump through an unrifled adapter. |
My 1 in 9 twist uppers work very well with conversion kits. Some ammo is a lot more accurate in the conversion kits than other brands so it helps to try a few different brands, The conversion kits are fine for plinking and shooting steel plates out to 100 yards. If you want to target shoot at paper and like small groups with a scope you'd be better off with a dedicated barrel IMHO. The conversion kits work very well for CQB training and are cheap and fun to shoot. I've never experienced any key holes but you get more fliers shooting the conversion kits in 1 in 9 twist barrels. I've never hurt any of my center fire rifles by using a conversion kit.
