- Contains integrated Last Round Bolt Hold Open (LRBHO) technology (PATENT PENDING) that reliably holds the bolt open when magazine is empty
- LRBHO feature is designed for lowers that accept Glock style magazines
- **NOTE — This upper is not machined for a gas tube as it is intended for blowback gas systems only
Once assembled the small “hook” end of the wire form in the upper should be pushed up by the follower of an empty Glock magazine which will engage the bolt catch on the last round fired to hold the bolt in the locked position. If it does not engage, or engages before the last round is fired you can make VERY SMALL adjustments by SLIGHTLY bending the “hook” end down to lock faster or up to lock slower. They are set and function checked during assembly with brand new Glock magazines and our standard bolt catches. Because of varying magazine specs, magazine specs changing over the life of the product, different thicknesses of the pad on the bolt catch and other variables, this adjustment may be necessary with your specific parts.
**NOTE: Some rail systems that use anti-rotation tabs may need slight modification to fit this upper. It is designed for flush mounting rails and standard hand guards.
The New Frontier Armory PC Upper (Gen 2) with LRBHO is proudly MADE IN THE USA by hard working American men and women.

New Frontier Product. Great Design! Gets the Job Done!
I purchased one of these to build an AR-40 Carbine. When I got it done I was pleased and impressed with how well it works including the LRBHO feature. I didn't even have to adjust it and it works for stock, extended, and drum mags! I bought a second for a 10MM PCC Carbine and I will buy a 3rd for a .357 SIG build! Clean and very well designed! A quality product and a price to be reconned with!
USGreat product

USNew Frontier PCC Stripped Upper Receiver…no need to look any further!
The NF stripped upper receiver is a perfect fit on my Cross Machine Tool 9mm Glock magazine lower. I like the simplicity of the last round bolt hold open feature. The fit and finish is excellent. You don’t need to look any further than this upper receiver to build your pistol caliber carbine.

USGreat Pistol Caliber Upper Receiver
If you want LRBHO and your lower doesn't have the mechanism, this is the upper you should get. Fit and finish is great and it assembled with ease to the lower.
