BCM SS410™ Barrels
This BCM stripped barrel is machined from a 410 stainless steel. It features hand lapped button rifling with a 1/8 twist rate and M4 feedramps. As with all BCM barrels it is proofed (HPT) and magnetic particle inspected (MPI). To give the shooter the best balance of weight and accuracy this BCM SPR barrel has a mid weight profile and a rifle length gas system. (410 stainless is a harder and more corrosion resistant than the conventional 416 stainless found in most barrels.)
Requires the use of the .750 gas block.

Worth the wait August 19, 2013
Reviewer: William Williams from Augusta, GA United States  
I recently got this barrel to finish a SPR build that I have been gathering the parts for two years. After a function test at my local indoor range at 25 yards, I was ready for the outdoor range. I took the finished rifle to the outdoor range and was more than pleased. This gun is a 1/2 MOA or better. This is just another BCM product that is outstanding. Thanks BCM.

BCM 18" SS410 March 30, 2012
Reviewer: irishman from Dayton, OH  
After lots of research and feedback I decided to go with  this barrel. Finally got out to shoot it today, paired with a SWFA SS scope and was very pleased with my groups using 55 grain PMC ammo. For the money you can't beat it. For future builds the SS410 will be my go to barrel. If you are looking to build an SPR look no further.

Overgassed, but accurate. September 23, 2011
Reviewer: Daniel B from Ishpeming, MI United States  
Nice barrel. 1/2" 5 shot groups @ 100m, not overly heavy, minimal fouling and easy to clean. But, it tears up the case heads, even using a H3 buffer. The gas port is .098"  about .008 to large. Guess I'll have to get an adj. gas block.

First complete build May 15, 2011
Reviewer: Jason Wood from California, MO United States  
This was my first complete, from stripped receiver up, build.  I had done several bolt guns previously. Choosing the barrel was the biggest sticking point on the entire build. I knew that I wanted an 18" but not what make.  After looking at about everything out there I came back to the BCM especially after learning who made the barrels. I am glad that I did. I have shot about 200 rds through it and not a trace of copper.  It has to be the smoothest barrel I have ever seen.  After a little load development I found that 77 gr SMK's are THE bullet to use.  I took my stepson on an outing today and he hit the 100% silhouette 23/25rds @500 yds the first time he had ever fired the rifle. This was in the rain with a 10mph wind. 20 of those were in a 8" group.
