Scooter's Review of Strike Industries SI-AR-15/M16 Receiver Extension,7 Position Assembly

Great product! I really like the extended detent tab. Makes for a secure install. Tube comes with a castle nut and endplate with variable sling mounts. I didn't use this piece and went for a simpler QD endplate. 7 positions for a bit more versatility.
Pros:
  • Perfect Fit
  • 7 positions
  • detent tab
Cons:
  • non
Best Used for:
  • replacement
  • Custom AR Build
