Wait a tic. Isn't building a silencer out of plastic akin to making football helmets from soggy doilies? You might think so, but the idea actually makes sense. The folks at Inland Manufacturing thought, Hey! The inside of suppressors just gets blown to smithereens anyway, and metal is heavy and 'clangy' sounding. Why don't we make suppressor guts out of plastic? Voila! Enter the PX-22 rimfire silencer. It's lightweight, quiet, and cheap. The outer aluminum tube and stainless steel base are the serialized parts, so swapping new internals is just a maintenance job. Even through the intestines are "disposable," early models are handling thousands of rounds with no ill effect. For now, you'll have to mail your suppressor to Inland to get new baffles installed, but if the Hearing Protection Act becomes law this year, you should be able to just order replacement baffles online. The retail price is just $189.95. If you're not familiar with suppressor prices, that's super-duper inexpensive.
