General F.A.Q.

1: What is .223 Wylde and what ammunition can I shoot?

.223 Wylde chamber is used on .223 caliber rifle barrels to allow them to safely fire either .223 Remington or 5.56x45mm NATO ammunition. This chamber was designed to exploit the accuracy advantages of the .223 Remington chambering without problems concerning over pressure or compromising the functional reliability of semi-auto firearms like the AR-15 family when using 5.56×45mm NATO military ammunition

7. I'm using a suppressor will your products work with suppressors?

Yes, our products will work with suppressors, however it is recommended that a gunsmith range rods the upper and suppressor to insure there will be no baffle strikes.

8. I ordered a nickel boron BCG. Do I still need lubricant?

Yes, you need to still lubricate the firearm, but minimal lubricant is needed as the coating helps retain lubricity.

9. I just bought a Radical Firearms upper/firearm what is the first thing I should do.

First check the barrel to confirm caliber as always with any firearm regardless of manufacturer. Clean the firearm well before heading out to the range. Check for any obstructions or leftover packing oil possibly in barrel bore.

10. I'm getting light strikes with 7.62x39.

Russian/ steel cased ammo has harder primers it is recommended to purchase brass ammunition.

11. I'm having accuracy issues with a barrel what should I do?

Verify barrel is clean. If it is clean then one should proceed to try different types of ammunitions as manufacture quality will vary from company to company. If no changes are seen Radical does warranty accuracy issues.

12. I Live in the state of Maryland...
