The Lantac M-Spec 5.56 Bolt Carrier Group is made to be affordable while still being made from high quality materials with select enhanced parts like the domed cam pin that reduces friction in the upper receiver and decreases parts wear. The bolt face is made from 158 carpenter steel or 9310 depending on supply, shot peened, and magnetic particle inspected. The carrier is cut to full auto M16 dimensions and is machined from 8620 steel and ground to exact Mil-Spec dimensions. The entire AR-15 BCG is black Nitride finished to improve surface hardness and smoothness over traditional Manganese Phosphate. This bolt carrier group is made in the U.S.A with a lifetime warranty.

So far so good

by -

Haven't put a lot of rounds through it yet, but so far so good. Smooth finish for lubricity and ease of cleaning. I'll give an update after a couple thousand rounds through it.

Great BCG Great parts

by

Awesome bcg that has smooth nitride with all quality parts including awesome domed cam pin….. no tool marks its totally perfect so grab one now!

A Very Nice BCG from a GREAT Company

by

This carrier is great quality which I expected from Lantac and they delivered! Very smooth and slick with zero tool marks and the bolt the same. The domed cam pin is a plus and when I installed and charged it a few times you really feel the buttery smooth action. If you want a top tier BCG at not a top tier price get this now! PA came thru lightning fast as always.

Well its mil-spec so...

It's mil-spec, nothing fancy, but guaranteed to get the job done. Made by Lantac, so quality should not be an issue. Comes with their polished and rounded cam pin which is supposed to make the action cycle smoother. I happen to have them in three of my rifles now after buying this carrier. When cycling the bolt by hand the action feels no different than with a standard pin. I'm not sure how big a difference, if any, it actually makes when firing the gun.

Quality

Quality bcg , I run them in every rifle I am able to.

Lantac makes quality, if everthing is like the one I got.

I dropped this into my Colt M4 and haven't looked back. Smooth running, easy to clean, keeps on running.

Perfect for my 12.5”

Fits perfect and runs smooth. No issues after 500 rounds. Easy to clean off. Very happy.

Lantac mil-spec BCG....

It's a great mil-spec BCG. Looks good. Runs great with no problems. I highly recommend catching it on sale like I did. It's nothing fancy, but runs great.

Value for the money

It’s a Lantec so it high quality. Staking was perfect and great cam pin. Got it on sale and what a deal. I’m very happy with it.
