Scorpio64 5,120 Posted January 12, 2018 If I am not putting a railed handguard on a rifle with a LR-308 high profile upper receiver, does it matter if the handguard is a low or high profile? The only accessory I will be using on the HG is a bipod. Quote Share this post Link to post Share on other sites
JackDaWack 2,894 Posted January 15, 2018 I'm not sure how the handguard could be classified as being high or low with out having any actual rails. If there are rail sections you can add then the top rail will not align. One will be slightly higher then the other. And have obvious issues with sights and Scopes. Either way it will work.

Scorpio64 5,120 Posted January 15, 2018 Well, I've found out that the main differences between high and low profile HG is the rail height and tube diameter. The low profile will mate to the receiver the same as the high and the gas block will clear the tube, so it should not be an issue. The tube I'm looking at has no Mlok or Keymod attach points so the only thing I'll have to work out is attaching a bipod stud. Quote Share this post Link to post Share on other sites

The only consistent factor for DPMS high and low is the hight of the top rail. Everything else should be the same. Quote Share this post Link to post Share on other sites
