Drop in for ar10 bushmaster 308 - Sniper AR .308 Quad Rail Handguards w/Triangle End

This product did fit very well for the price remember its from China. But you get what you pay for, the metal used seemed brittle the edges very sharp and it did not come with the rubber guards that come with American made products. If you are going to use this product without a bi pod it will most likely bloody your hand up. Especially since its a 308 bullet.
If you are looking to go inexpensive and want something that will drop in for triangle end cap and high profile gas block this is a good thing to buy.
