thanks for the quick reply!!
where does one get a 12'' 10/22 barrel? ive actually never seen any! does the kit need a 10/22 barrel with front site or will a target barrel do?
im sure im not the only one wondering if the 10/22 they have will work with the kit or will they hafto get a new one to buy your kit or atleast get a new barrel
The only barrel that does not work with the Thompson kit is the target barrel due to its diameter. The foregrip will not fit properly. I guess you could carve it out a bit more to fit the target barrel. The standard Ruger barrels all work fine. Some retailers, including ours, do carry shorter barrels. I bought an 8.5" barrel from FabSports last year for my MP5 project. As stated earlier, our retailer is working toward being able to supply 12" barrels hopefully by the time we are ready to release the kit. But it is just one option. Your standard Ruger barrel will be a perfect fit.
With regard to the front sight, you won't be using the front sight at the muzzle of your barrel anymore. The new front sight is located at the front of the receiver. Its small and unobtrusive but fast and easy to aquire the target and it doesn't take away from the Thompson look.
