Letter Re: .22 Rimfire Kits for Battle Rifle Training

Hello, Mr. Rawles.
On your advice I read Boston’s Gun Bible and became convinced that I should get a .308 rifle. I bought the HK91, mostly on faith since I have never shot, let alone owned, a FAL, M1A, or AR-10. No one I know has any of these. And with ammo prices going up as much as they have, I decided to get the .22 [Long Rifle rimfire] conversion kit for the HK91. I paid a little under $500 (they were $400 a couple months ago, and there were a lot more available.) But since .22 ammo is so much cheaper than .308 ammo, I figured that the conversion kit would pay for itself after shooting about 1200 rounds of .22 instead of .308. I realize that practicing using the .22 conversion kit only comes so close to shooting .308, but I can still practice weapons familiarity, using the sights, trigger pull, etc.

When I first shot .22 [rimfire] through the HK91 I wasn’t sure the round left the chamber. The weapon barely moved, since shooting a measly .22 round is nothing for the rifle. This actually was something I really liked, because I could get used to firing the weapon and avoiding bad habits like, flinching, or jerking. I only had four malfunctions when I shot about 700 rounds of .22: one was from a dud, and three were mag feed problems (all with the second to the top round in the magazine, something with the spring I suppose). Shooting .22 through the HK91 was very accurate! I had thought that the conversion kit might be okay for beginners and I was expecting it to malfunction once in awhile, since the weapon was not really designed for it. So I was very happy that it was all so reliable. Obtaining the .22 conversion kit was not a factor in my decision to get an HK91, but it would be now if I were to do it again. I haven’t seen too many conversion kits for other .308 battle rifles, so I take it as a big plus that I can get an original HK conversion kit that is super reliable. I think it’s a great way not only to save money with weapons practice, it might also help others move into using my HK91 by starting them off using the lower caliber conversion kit.

I have decided to get all original HK parts and accessories. The quality I’ve experienced is worth it. I realize that other rifles, like the M1A, may be more accurate, but at my skill level, I don’t think it really matters. I’m still practicing using iron sights at 100 yards. Plus, I want mine to go boom (and hit the target) when I pull the trigger. I prefer revolvers for the same reason. If I were a better shooter, accuracy would probably be a bigger factor. If I were better at combat reloading, then I might like the FAL more. I also don’t have the money, and maybe time, to make many modifications to my weapons, so I really like how everything about the HK91 just plain works out-of-the box. I haven’t heard of anyone suggesting making modifications to it at all. I was thinking about getting different scopes (like one for night vision, another for daylight) and getting a separate STANAG claw mount for each one. I figured that way I could change scopes on my HK91 and have them all retain zero, but I’d like your opinion on that.

I appreciate your blog and I have taken the challenge to donate 10 cents a day because I have learned so much. However I don’t think I’ll ever be nearly as skilled, knowledgeable, or equipped as some of your other readers. I won’t be able to get that secluded property, I won’t be able to get a battery of weapons or make nice modifications to them, I won’t be able to get a converted 4-wheeler that runs on vegetable oil, at least not anytime soon, but I am staying out of debt, and I am keeping my ear to the ground and staying nimble for whatever comes down the road. I have recognized that a skill that I have lacked is that of a rifleman, and I am trying to become one, both for my family and my fellow countrymen. Thanks, – A Rifleman in Training

JWR Replies: You are to be commended from you efforts! Get some training from experts. Even if you can’t a afford a trip to Front Sight, keep in mind that both the RWVA/Appleseed Project. and the Western Rifle Shooters Association (WRSA) offer inexpensive but very effective training for riflemen.

In addition to the HK sub-caliber kit that you mentioned, there are .22 rimfire kits available for a variety of .223 rifles including the AR-15/M4 family and the Ruger Mini-14. Similar kits were also made for FALs and L1A1s, but sadly they are very expensive. With the current high cost of most centerfire ammunition, buying a .22 kit makes a lot of sense. I have also found that being able to shoot .22 rimfire through a battle rifle is useful for transitioning youths to high power shooting.

The original HK claw mounts have fairly consistent return to zero, so I do indeed recommend them.
