Good question!
I got my rifleman patch last year, and I’ve done 4 events this year as an IIT.
The rifle I used to make rifleman was a Ruger 10/22 “deluxe”. That would be the standard barrel, but with the walnut stock that doesn’t have a barrel band. Optic is a Leupold VX Freedom 2-7x33 rimfire scope. The only mods that were done to the rifle was the auto-bolt release, extended mag release (what comes factory on10/22s with a plastic trigger guard now), swapped the factory sling loops for sling studs and a “pop can” aluminium shim was put under the V-block to ensure the barrel was free floated.
This last summer, that same rifle was loaned out at all 4 events I attended as an IIT, 2 out of 4 “borrowers” got their patch with that rifle.
I’ve seen people get their patch with a bolt action, but I would not recommend one for a first timer. Until a person is proficient on nailing down their NPOA quickly, having to move your trigger hand to run the bolt will add a level of difficulty that is “sub-optimal”. The same goes for tube fed semi’s or lever guns. It can be done, and it’s “cool as heck” to see them on the line. It’s even cooler when the person who brought the rifle knows how to run it! But, again, it adds that level of difficulty that can (and usually does) add more anxiety and mucks with your NPOA and your mental headspace. Remember, the MQT is a timed event. Time you spend on reloading or manipulating your rifle is time that can’t be spent on ensuring good NPOA, breathing and sight picture.
I would recommend a semi-auto. Pick your poison, it doesn’t matter which brand, make or model. Ensure you have 10 round magazines.
I would also recommend that the rifle be tested and ensure that the rifle is capable of running 500 rounds (of the ammunition you plan to use) without malfunction.
I would recommend an optical sight, either a straight 4x or an adjustable one that goes no higher than 7x. I really like my 2-7, it just works well on 2x for the standing stage, 4x for sitting or kneeling and 7x while prone. A 4x will do quite nicely for all 4 positions. A 3-9 would also be OK, the problem with a 9x is that it narrows your sight picture quite a bit and I have seen people place their rounds on their neighbours targets because of this. Iron sights can also be used, but it can be a handicap.
I would also recommend the installation of sling studs before the event. There is no time at the event to instal them and the Mapleseed is all about how to utilize a sling. That said, if you don’t have studs, we can make it work.... it will involve zip-ties, tape and perhaps some chewing gum, but we will get a sling on there for you!
Do not worry about bringing a sling, it is better to have no sling than a sling that doesn’t work the way you will need it to. We will have loaners at the event. If you “absolutely” must bring a sling, the web USGI style sling (the inexpensive ones come with the Chinese M305 rifles) are the ones we recommend.
All that said, it’s a great time with good people and as long as you bring an open mind and a “teachable attitude” you’ll have a great day.
Cheers!
