Known for over-the-top grips (more on that later), their Grip Screw Bushings are a brilliant solution to the nerve-wracking issue of dealing with classic 1911 grip screw bushings--likely the single most-bunged up bit on a 1911.
The course will be divided into ten sections, including rubber types and compounds; bushing types and how to size; two-part moldings and hydro-bushings; inner and outer metals and adhesion preparation; bushing static rate calculations; finite element analysis; static and dynamic testing; vehicle development; fatigue methods; and miscellaneous topics.
Longer life of 7 to 10 times that of standard steel-backed, bronze-sintered and PTFE overlay bushings, such as the TSA (formerly BK-1W) and DU bushing
In July's column on sprue bushings we discussed how to reduce the mass of plastic where the sprue, runner, and cold well intersect at the parting line.
As we go to press in early August, Lycoming, field shops and owners were struggling to clarify a service bulletin that requires inspection and possible replacement of connecting rod bushings in hundreds of Lycoming engines.
With this many change outs, the grip screws and grip screw bushings can give us trouble.

To minimize such vibrations, rubber parts are used extensively at mounting points for the cabin, such as engine mountings and suspension bushings.
I have made a lot of these adapter bushings since I have done a lot of special AR projects that featured self-made barrels.
To make the 10/22 barrel fit an AR-15, the barrel will be re-profiled and bushings will be fabricated to adapt the barrel to the AR receiver.
That may help work out your frustrations, but it causes damage to the pin and bushings.
