Apex Grade Semi Drop-In M&P Barrel - 5"

What It Does 
The Mk 1 Apex Grade Semi Drop-In 5" Barrel is designed for the 9mm Smith & Wesson M&P. Due to the tolerance variations in the M&P Slide, the barrel is semi drop-in. In some cases this means the barrel may drop-in without alteration, but in most cases will likely require minor fitting which is easily done by the end user. The stainless steel barrel features a 1:10” twist rate. The design increases accuracy performance making the M&P capable of shooting as small as a 1-1/2 inch grouping at 25 yards. Accuracy test results based on use of a mechanical rest. Final results may vary based on shooter ability, ammunition selection and variations in factory firearm tolerances.

Expected Results 
– Direct replacement of factory 5.00" barrel 
– Improves accuracy 
– Optimal performance seen with bullet weights of 115gr. through 147gr. using 9mm jacketed ammunition 
– Due to variations in factory slide tolerances, slight fitting may be required and is easily performed by the end user

Applicable To What Gun(s) 
Works with all Smith & Wesson 9mm M&P pistols requiring a 5” barrel.
